Before this change, we would see "connection reset" when sending the
initialize
request over SSH in the case that the debug adapter was slow to boot.

(Although we'd have successfully created a connection to the local SSH
port,
trying to read/write from it would not work until the remote end of the
connection had been established)

Fixes  #32575

Release Notes:

- debugger: Fix connecting to a Python debugger over SSH

Before this change, when spawning a child session we'd launch an extra
node process that would immediately die because it couldn't listen on
the debugger port

Release Notes:

- N/A

We were translating port configuration incorrectly, using it for both
attach target and debugger port.
This however meant that we were spawning a 2nd process that'd listen on
the same port as the existing debugger.

Closes #32836

Release Notes:

- debugger: Fixed issues with auto-translated Visual Studio Code debug
configs for attaching to existing node debugger instances.

Closes #32849

Release Notes:

- Fixed overly strict validation of Go debugging configurations.

This should silence a noisy log we see whenever a debug session is
started:
`2025-06-17T12:06:12+02:00 ERROR [project] no adapter running to send
request: ThreadsCommand`

Closes #ISSUE

Release Notes:

- Fixed debugger logs getting clobbered with internal logs about Threads
Command whenever a new debug session is created.

We'll now clean up DAP locators for unloaded extensions and load schemas
proper

I can now load a custom Ruby extensions with all bells and whistles and
use it as my debugger.

Release Notes:

- N/A

- [x] foreground highlights
- [x] background highlights
- [x] advertise support in DAP capabilities

Closes #31372

Release Notes:

- Debugger Beta: added basic support for highlighting in the console
based on ANSI escape codes.

Closes #31574 

Move this button a bit to the left so it doesn't get blocked by the
hitbox of the scrollbar.

Also makes the list entries a bit thicker vertically so that the button
can be `XSmall` instead of `Indicator`-sized again.

Release Notes:

- Debugger Beta: fixed a layout issue that made it hard to click the
remove (`X`) button for entries in the breakpoint list.

Closes #32688

Release Notes:

- Fixed tasks (including build tasks for debug configurations) silently
using `/` as a working directory when the specified `cwd` didn't exist.

Cherry-picked Attempt to log error instead of crash in bracket
highlighting (#32837)

Crashes look like:

```
Panic `offset 632 is greater than the snapshot.len() 631` on thread 0 (com.apple.main-thread)

<multi_buffer::MultiBufferSnapshot>::innermost_enclosing_bracket_ranges::<usize>
editor::highlight_matching_bracket::refresh_matching_bracket_highlights
<gpui::app::App>::update_window_id::<bool, <gpui::app::context::Context<editor::Editor>>::subscribe_in<multi_buffer::MultiBuffer, multi_buffer::Event, <editor::Editor>::on_buffer_event>::{closure#0}::{closure#0}>::{closure#0}
<gpui::app::context::Context<editor::Editor>>::subscribe_in::<multi_buffer::MultiBuffer, multi_buffer::Event, <editor::Editor>::on_buffer_event>::{closure#0}
<gpui::app::App>::flush_effects
<project::lsp_store::LocalLspStore>::format_buffer_locally::{closure#0}
<project::lsp_store::LspStore>::format::{closure#1}::{closure#0}::<i32>
```

Though `format_buffer_locally` is not always present. Both issue reports
mention usage of the agent. I suspect this is somehow a result of agent
format-on-save combined with the user's cursor being at the end of the
buffer as it's getting edited by the agent.

The offsets are always off-by-one in the error, so at first I thought
the issue was the condition `head < snapshot.buffer_snapshot.len()`
before setting `tail` to be `head + 1`, but an offset equal to len is
valid. Seems like to get a `to_offset` crash, `head` must be greater
than `len`. Which is quite weird, a selection's offset should never be
out of bounds.

Since this code is just about highlighting brackets, this PR logs an
error instead of crashing in the `head > len` case.

Closes #32732, #32171

Most of the default icon sets on Ubuntu do not use the names that were
there. To fix, using the icon synonyms from the chromium source. This
will probably fix some of the linux mouse cursor issues tracked in
https://github.com/zed-industries/zed/issues/26141

Also adds a note in the load failure logs mentioning that misconfigured
XCURSOR_PATH may be the issue. I ran into this because
https://github.com/snapcrafters/alacritty/issues/21.

On X11 also adds:

Caching of load errors to log once for missing cursor icons.

Fallback on default cursor icon. This way if there was a transition from
a non-default icon to a missing icon it doesn't get stuck showing the
non-default icon.

Leaving release notes blank as I have other mouse cursor fixes and would
prefer to just have one entry in the release notes.

Release Notes:

Linux: Fixed a couple bugs that can cause the mouse cursor to not appear
or only appear as an arrow

This PR addresses an issue where we could get a stack frame list and
automatically select a stack frame that didn't have a valid path.
Causing a failure on Zed's end to select/update the active debug line.
The fix for this is selecting the first non-subtle stack frame that has
the optional path parameter.

We also made subtle stack frames move into their own collapsable list as
well.

This PR fixes a common issue where a debug session won't start up and
user's weren't able to get any logs from the debug session. We now do
these three things

1. We know store a history of debug sessions
2. We added a new option to only look at the initialization sequence 
3. We default to selecting a session in dap log view in stead of none

- debugger: Add history to debug session logging
