We'll now add panels to the workspace as soon as they're ready rather
than waiting for all the rest to complete. We should strive to make all
panels fast, but given that their load tasks are fallible and do IO,
this approach seems more resilient.

Additionally, we'll now start loading the agent panel at the same time
as the rest.

This reverts commit 79be5cbfe21eabeadb2d910d4ba7c355256bd0e3.

The bug is in the `place_near` logic, specifically the
`!row_block_types.contains_key(&(row - 1))` check. The problem isn’t
really that condition itself, but it’s that it relies on
`row_block_types`, which does not take into account that upon block
resizes, subsequent block start row moves up/down. Since `place_near`
depends on this incorrect map, it ends up causing incorrect resize syncs
to the block map, which then triggers more bad recursive calls. The
reason it worked till now in most of the cases is that recursive resizes
eventually lead to stabilizing it.

Before `place_near`, we never touched `row_block_types` during the first
prepaint pass because we knew it was based on outdated heights. Once all
heights are finalized, using it is fine.

The fix is to make sure `row_block_types` is accurate from the very
first prepaint pass by keeping an offset whenever a block shrinks or
expands. Now ideally it should take only one subsequent prepaint. But
due to shrinking, new custom/diagnostics blocks might come into the view
from below, which needs further prepaint calls for resolving. Right now,
tests pass after 2 subsequent prepaint calls. Just to be safe, we have
set it to 5.

Release Notes:

- Fixed an issue where Zed did not respect the `on_last_window_closed`

I was trying to use Zed for Rust debugging on windows, but was getting
this warning in debugger console: "Could not initialize Python
interpreter - some features will be unavailable (e.g. debug
visualizers)."
As the warning suggests this led to bad debugging experience where the
variables were not visualized properly in the "Variables" panel.

After some investigation I found that the problem is that Zed silently
failed to extract all files from the debug adapter package
(https://github.com/vadimcn/codelldb/releases/download/v1.11.8/codelldb-win32-x64.vsix).
Particularly `python-lldb` folder was missing, which caused the warning.
The error occurred here:

https://github.com/zed-industries/zed/blob/cf7c64d77f1806cdd34b3812bbf27681fb3cb905/crates/util/src/archive.rs#L47
And then gets ignored here:

https://github.com/zed-industries/zed/blob/cf7c64d77f1806cdd34b3812bbf27681fb3cb905/crates/dap/src/adapters.rs#L323-L326
The simple fix is to update `async_zip` crate to version 0.0.18 where
this issue appears to be fixed. I also added logging instead of silently
ignoring the error, as I believe that would have helped to catch it
earlier.

To reproduce the original issue you can try to follow these steps:
0. (Optional) Remove/rename old codelldb adapter at
`%localappdata%\Zed\debug_adapters\CodeLLDB`. Restart Zed.
1. Create a simple Rust project. Make sure you use gnu toolchain (target
`x86_64-pc-windows-gnu`)
```rust
fn world() -> String {
    "world".into()
}

fn main() {
    let w = world();
    println!("hello {}", w);
}
```

2. Put a breakpoint on line 7 (`println`)
3. In the command palette choose "debugger: start" and then select "run
*crate name*"

Small QOL improvement for branch picker to only dismiss when focus lost
in active window.
This can benefit those who need to switch windows mid branch creation to
fetch correct jira ticket number or etc.

Added `window.is_active_window()` guard in `picker.rs` -> `cancel` event

Release Notes:

automatically close upon the window becoming inactive.

We install phpactor by default, but on windows it doesn't work out of
the box (see
[here](https://github.com/phpactor/phpactor/discussions/2579) for
details). For now we'll default to using intelephense, but in the future
we'd like to switch back if phpactor lands windows support given that
it's open source.

Release Notes:

- Added the newly released Gemini 3 Pro Preview Model


https://docs.cloud.google.com/vertex-ai/generative-ai/docs/models/gemini/3-pro

https://github.com/zed-industries/zed/pull/40883 implemented this
incorrectly. It was marking a random background thread as a wasm thread
(whatever thread picked up the wasm epoch timer background task),
instead of marking the threads that actually run the wasm extension.

This has two implications:
1. it didn't prevent extension panics from tearing down as planned
2. Worse, it actually made us hide legit panics in sentry for one of our
background workers.

Now 2 still technically applies for all tokio threads after this, but we
basically only use these for wasm extensions in the main zed binary.

- Fixed extension panics crashing Zed on Linux

This PR updates window background rendering to use the **official DWM
backdrop API** (`DwmSetWindowAttribute`) instead of the legacy
`SetWindowCompositionAttribute`.
It also adds **Mica** and **Mica Alt** options to
`WindowBackgroundAppearance` for native Windows 11 effects.

### Motivation

Enables modern, stable, and GPU-accelerated backdrops consistent with
Windows 11’s Fluent Design.
Removes reliance on undocumented APIs while maintaining backward
compatibility with older Windows versions.

### Changes

* Added `MicaBackdrop` and `MicaAltBackdrop` variants.
* Switched to DWM API for applying backdrop effects.
* Verified fallback behavior on Windows 10.

### Release Notes:

- Added `WindowBackgroundAppearance::MicaBackdrop` and
`WindowBackgroundAppearance::MicaAltBackdrop` for Windows 11 Mica and
Mica Alt window backdrops.

### Screenshots

- `WindowBackgroundAppearance::Blurred`

Closes #ISSUE

The model often uses the wrong closing tag, or has spaces around the
closing tag name. This PR makes it so that opening tags are treated as
authoritative and any closing tag with the name `new_text` `old_text` or
`edits` is accepted based on depth. This has the additional benefit that
the parsing is more robust with contents that contain `new_text`
`old_text` or `edits. I.e. the following test passes

```rust
    #[test]
    fn test_extract_xml_edits_with_conflicting_content() {
        let input = indoc! {r#"
            <edits path="component.tsx">
            <old_text>
            <new_text></new_text>
            </old_text>
            <new_text>
            <old_text></old_text>
            </new_text>
            </edits>
        "#};

        let result = extract_xml_replacements(input).unwrap();
        assert_eq!(result.file_path, "component.tsx");
        assert_eq!(result.replacements.len(), 1);
        assert_eq!(result.replacements[0].0, "<new_text></new_text>");
        assert_eq!(result.replacements[0].1, "<old_text></old_text>");

Release Notes:

### What this solves

This PR adds support for HTTP and SSE (Server-Sent Events) transports to
Zed's context server implementation, enabling communication with remote
MCP servers. Currently, Zed only supports local MCP servers via stdio
transport. This limitation prevents users from:

- Connecting to cloud-hosted MCP servers
- Using MCP servers running in containers or on remote machines
- Leveraging MCP servers that are designed to work over HTTP/SSE

### Why it's important

The MCP (Model Context Protocol) specification includes HTTP/SSE as
standard transport options, and many MCP server implementations are
being built with these transports in mind. Without this support, Zed
users are limited to a subset of the MCP ecosystem. This is particularly
important for:

- Enterprise users who need to connect to centralized MCP services
- Developers working with MCP servers that require network isolation
- Users wanting to leverage cloud-based context providers (e.g.,
knowledge bases, API integrations)

### Implementation approach

The implementation follows Zed's existing architectural patterns:

- **Transports**: Added `HttpTransport` and `SseTransport` to the
`context_server` crate, built on top of the existing `http_client` crate
- **Async handling**: Uses `gpui::spawn` for network operations instead
of introducing a new Tokio runtime
- **Settings**: Extended `ContextServerSettings` enum with a `Remote`
variant to support URL-based configuration
- **UI**: Updated the agent configuration UI with an "Add Remote Server"
option and dedicated modal for remote server management

### Changes included

- [x] HTTP transport implementation with request/response handling
- [x] SSE transport for server-sent events streaming
- [x] `build_transport` function to construct appropriate transport
based on URL scheme
- [x] Settings system updates to support remote server configuration
- [x] UI updates for adding/editing remote servers
- [x] Unit tests using `FakeHttpClient` for both transports
- [x] Integration tests (WIP)
- [x] Documentation updates (WIP)

### Testing

- Unit tests for both `HttpTransport` and `SseTransport` using mocked
HTTP client
- Manual testing with example MCP servers over HTTP/SSE
- Settings validation and UI interaction testing

### Screenshots/Recordings

[TODO: Add screenshots of the new "Add Remote Server" UI and
configuration modal]

### Example configuration

Users can now configure remote MCP servers in their `settings.json`:

```json
{
  "context_servers": {
    "my-remote-server": {
      "enabled": true,
      "url": "http://localhost:3000/mcp"
    }
  }
}
```

### AI assistance disclosure

I used AI to help with:

- Understanding the MCP protocol specification and how HTTP/SSE
transports should work
- Reviewing Zed's existing patterns for async operations and suggesting
consistent approaches
- Generating boilerplate for test cases
- Debugging SSE streaming issues

All code has been manually reviewed, tested, and adapted to fit Zed's
architecture. The core logic, architectural decisions, and integration
with Zed's systems were done with human understanding of the codebase.
AI was primarily used as a reference tool and for getting unstuck on
specific technical issues.

Release notes:
* You can now configure MCP Servers that connect over HTTP in your
settings file. These are not yet available in the extensions API.
  ```
  {
    "context_servers": {
      "my-remote-server": {
        "enabled": true,
        "url": "http://localhost:3000/mcp"
      }
    }
  }
