Release Notes:

## Overview
- document how to keep a per-user debug.json so global launch tasks show
up everywhere (Fixes #39849)
- sanitize REPL terminal text before copying so error blocks can be
copied and opened in buffers (Fixes #40207)

## Design Decisions
- reused the existing user debug file (paths::debug_scenarios_file) and
pointed docs at the zed::OpenDebugTasks command to stay aligned with the
settings UX
- extract a sanitize helper inside TerminalOutput::full_text to strip
\r/null padding while keeping indentation intact, then join the cleaned
lines so clipboard and buffers get readable text

## Testing
- Not run (cargo is unavailable in this environment)

Fixes #39849.
Fixes #40207.

Add support for GithubCopilot /responses endpoint. This gives the
copilot chat provider the ability to use the new GPT-5 codex model and
any other model that lacks support for /chat/copmletions endpoint.

Closes #38858 

Release Notes:

- Add support for GithubCopilot /responses endpoint.

# Added
1. copilot_response.rs that has the /response endpoint types
2. uses response endpoint if model does not support /chat/completions.
3. new into_copilot_response() to map LanguageCompletionEvents to
Request.
4. new map_stream() to map response stream event to
LanguageCompletionEvents and tests.
5. Fixed a bug where trying to parse response for non streaming for
/chat/completion was failing

# Notes
There is a pr open - https://github.com/zed-industries/zed/pull/39989
for adding /response support for OpenAi and OpenAi compatible API.
Altough they share some similarities (copilot api seems to mirror openAi
directly) ive simplified some stuff and tried to keep it the same with
the vscode-chat implementation where possible. There might be a case for
code reuse but i think keeping them separate for now should be ok.

Very often, when I'm testing or playing around with the zoom feature,
including the agent panel, I find myself missing one quick action that
would bring everything back to normal. That's what `ResetAllZoom` does.
If you have customized your zoom level in all areas of Zed, that action
returns everything to its default state. Similarly, if you're playing
around with zoom just in the agent panel, `ResetAgentZoom` does the same
in that context.

Release Notes:

- Added the `ResetAllZoom` and `ResetAgentZoom ` actions, allowing to
return the zoom level across the whole app and/or just in the agent
panel to its default/original value.

Closes https://github.com/zed-industries/zed/issues/41094

This PR adds the `agent_buffer_font_size` settings to be scaled in the
same proportion as the agent panel's UI font size, which was the only
setting that was being accounted for. This is something that I forgot to
do when we broke down the agent panel's font size controls into these
two values.

Release Notes:

- agent: Fixed an issue where the agent panel's buffer and UI font size
wouldn't scale proportionally.

Closes #ISSUE

Release Notes:

- Fixed an issue where having a correct `file_finder.include_ignored`
setting would result in failed to migrate errors

Release Notes:

- Fix duplicate process entries in WSL debug attach list

Update `project::buffer_store::BufferStore.save_buffer_as` in order to
correctly update the `path_to_buffer_id` hash map, ensuring that the
currently open file's path is dissociated from the buffer's id, to
prevent the new buffer from being open when trying to open the original
file.

Closes #29783 

Release Notes:

- Fixed issue where using `workspace: save as` would prevent users from
opening the original file from which the new file was created

This PR removes the behavior that the number_field changes focus to the
previous element when using the decrement button.

I mainly noticed this while decreasing the tab-size of a language, since
it there closes the page...

Please note that I am unsure what if any purpose this code has.
I was unable to find a use case and since it is not present in the
`increment_handler` I guess it should never have been here

Release Notes:

* Fixed wrongly focus previous element on number_field decrement

Release Notes:

- Enabled automatic import organization, via
[ruff](https://github.com/astral-sh/ruff), when saving Python files. To

The leak mainly showed up in the appearance page because it had a lot of
dropdown menus. The problem occurred because the drop-down menus were
creating a new entity on each frame instead of using the
`window.use_state...` API.

Closes https://github.com/zed-industries/zed/issues/38453

Current `Buffer` API only allows getting buffer text with `\n` line
breaks — even if the `\r\n` was used in the original file's text.

This it not correct in certain cases like LSP formatting, where language
servers need to have original document context for e.g. formatting
purposes.

Added new `Buffer` API, replaced all buffer LSP registration places with
the new one and added more tests.

Release Notes: 

- Fixed ESLint linebreak-style errors by preserving line endings in LSP
communication

Closes #39654

Release Notes:

- Fixed the formatting of macOS and Linux keybindings in the Zed docs to

Previously we had `Context` and `ContextStore` in both `agent_ui` (used
to store context for the inline assistant) and `assistant_context` (used
for text threads) which is confusing.
This PR makes it so that the `assistant_context` concepts are now called
`TextThread*`, the crate was renamed to `assistant_text_thread`

Release Notes:

- N/A

Updates #40531, restoring the previous behavior which didn't surface an

Release Notes:

This PR does two related things:

- First, it gets rid of the undifferentiated `RepositoryEvent::Updated`
in favor of three new events that have clearer definitions:
`BranchChanged`, `StashEntriesChanged`, and `StatusesChanged`. An
implication of this is that we no longer emit a `RepositoryEvent` unless
some git state changed; previously we would emit `RepositoryUpdated`
after doing a git status scan even if no statuses changed.
- Second, it changes the subscription strategy of the project diff to
make it update more robustly. Previously, the project diff only
subscribed to the `GitStore`, so it relied on getting a `GitStoreEvent`
when some buffer's diff hunks changed, even if the git status of the
buffer's file didn't change (e.g. a second hunk in a file that was
already modified). After this PR, it also subscribes to the individual
`BufferDiff` entities for buffers that have a git status, so the
`GitStore` is freed from that responsibility. This also fixes some real
cases where the previous strategy was not effective in keeping the
project diff up to date (captured in a test).

Release Notes:

- Fixed some cases where the project diff would fail to update in
response to git events.

Release Notes:

- `vim::NormalBefore` now enters `helix_normal` correctly.

Release Notes:

- helix: Re-ordered `helix_normal || helix_select` keybindings to follow the
same order as the keymap on the helix-editor
[documentation](https://docs.helix-editor.com/keymap.html).
- helix: Added `alt-o` & `alt-i` to Select larger and smaller syntax node

Release Notes:

- Fixed panic in copy highlight json action

This shrinks it from roughly a ~kilobyte to 8 byte, removing a bunch of

we do clone it a couple times here and there, making that also a fair
bit cheaper
