This PR is an additive change introducing the `truncate_start` method to
labels, which gives us the ability to add an ellipsis at the beginning
of the text as opposed to the regular `truncate`. This will be generally
used for truncating file paths, where the end is typically more relevant
than the beginning, but given it's a general method, there's the
possibility to be used anywhere else, too.

Closes #42268
We've migrated user selections when a given workspace has a single
worktree (as then we could determine what the target worktree is).

Release Notes:

- python: Fixed selected virtual environments not being
persisted/deserialized correctly within long-running Zed sessions (where
multiple different projects might've been opened). This is a breaking
change for users of multi-worktree projects - your selected toolchain
for those projects will be reset.

Closes #44955 

Release Notes:

repository/branch context in multi-repository projects when repo/branch
switched manually from the Git panel.

It will run weekly and it promised not to touch issues of the wrong
types anymore.

The size and spacing around the traffic light buttons changes after
macOS SDK 26. Our official builds aren't using this SDK yet, but dev
builds sometimes are and the official will in the future.

Closes #23367 

**Summary**
- Prevents inline diagnostics, code actions, blame annotations, and
hover popovers from overlapping with the right-click context menu by
checking for `mouse_context_menu` presence before rendering these UI
elements.

PS: Same behaviour is present in other editors like VS Code.

## Summary

Fixes arithmetic underflow panics in `terminal_scrollbar.rs` by
converting unsafe subtractions to `saturating_sub`.

Closes #45281

## Problem

Two locations perform raw subtraction on `usize` values that panic when
underflow occurs:

- `offset()`: `state.total_lines - state.viewport_lines -
state.display_offset`
- `set_offset()`: `state.total_lines - state.viewport_lines`

This happens when `total_lines < viewport_lines + display_offset`, which
can occur during terminal creation, with small window sizes, or when
display state becomes stale.

## Solution

Replace the two unsafe subtractions with `saturating_sub`, which returns
0 on underflow instead of panicking.

Also standardizes the existing `checked_sub().unwrap_or(0)` in
`max_offset()` to `saturating_sub` for consistency across the file.

Closes #24264

- Both the mode, profile, and model selectors have the option to cycle
through its options with a keybinding. In the tooltip that shows it, in
some of them the "Cycle Through..." label was at the top, and in others
at the bottom. Now it's all at the bottom.
- We used different language in different places for "going to a file".
The tool call edit card's header said "_Jump_ to File" while the edit
files list said "_Go_ to File". Now it's both "Go to File".

I wanted a way to make it easy to figure out which version of a language
server Zed is running. Now, you get a tooltip when hovering on a
language server in the Language Servers popover.

src="https://github.com/user-attachments/assets/1ced4214-b868-4405-8881-eb7c0b75a53e"
/>

This PR also fixes a bug. We had existing code to open a tooltip on
these language server entrees and display the language server message,
which was never fully wired up for `CustomEntry`s. Now, in this PR, we
will show show either version, message, or both, in the documentation
aside, depending on what the server has given us.

Mostly done with Droid (using GPT-5.2), with manual review and multiple
follow ups to guide it into using existing patterns in the codebase,
when it did something abnormal.

Release Notes:

- Added language server version in a tooltip on language server hover

This PR simplifies how we display thread timestamps in the agent panel's

how many days ago that thread was had in. Hovering over the thread item
shows you both the title and the full date, if needed (time and date).

We can first review to ensure this change meets both `Zed` and user
requirements, as well as code rules. Currently, we only support
user-level settings. We can wait for this PR:
https://github.com/zed-industries/zed/pull/43173 to be merged, then
modify it to support both user and project levels.

When profiling Zed with Instruments, a warning appears indicating that
surfaces cannot be pushed directly to the display as they are
non-opaque. This happens because the metal layer is currently marked as
non-opaque by default, even though the window itself is not transparent.

<img width="590" height="55" alt="image"
src="https://github.com/user-attachments/assets/2647733e-c75b-4aec-aa19-e8b2ffd6194b"
/>

Metal on macOS can bypass compositing and present frames directly to the
display when several conditions are met. One of those conditions is that
the backing layer must be declared opaque. Apple’s documentation notes
that marking layers as opaque allows the system to avoid unnecessary
compositing work, reducing GPU load and improving frame pacing

Ref:
https://developer.apple.com/documentation/metal/managing-your-game-window-for-metal-in-macos

This PR updates the Metal renderer to mark the layer as opaque whenever
the window does not use transparency. This makes Zed eligible for
macOS’s direct-to-display optimization in scenarios where the system can
apply it.

Release Notes:

- gpui: Mark metal layers opaque for non-transparent windows to allow
direct-to-display when supported

Closes #ISSUE

Removes a few eager container clones and iterations.

Added a todo to `get_prev_tab_group_window` and
`get_next_tab_group_window`. They seem to use `HashMap::keys()` for
choosing the previous tab group, however `.keys()` returns an arbitrary
order, so I'm not sure if previous actually means anything here. Conrad
seems to have worked on this part previously, maybe he has some
insights. That can possibly be a follow-up PR, but I'd be willing to
work on it here as well since the other changes are so simple.

Closes #ISSUE

A [modal dialog](https://en.wikipedia.org/wiki/Modal_window) window is a
window that demands the user's immediate attention and blocks
interaction with other parts of the application until it's closed.

- On Windows this is done by disabling the parent window when the dialog
window is created and re-enabling the parent window when closed.
- On Wayland this is done using the
[`XdgDialog`](https://wayland.app/protocols/xdg-dialog-v1) protocol,
which hints to the compositor that the dialog should be modal. While
compositors like GNOME and KDE block parent interaction automatically,
the XDG specification does not guarantee this behavior, compositors may
deliver events to the parent window unfiltered. Since the specification
explicitly requires clients to implement event filtering logic
themselves, this PR implements client-side blocking in GPUI to ensure
consistent modal behavior across all Wayland compositors, including
those like Hyprland that don't block parent interaction.
- On X11 this is done by enabling the application window property
[`_NET_WM_STATE_MODAL`](https://specifications.freedesktop.org/wm/latest/ar01s05.html#id-1.6.8)
state.

I'm unable to implement this on MacOS as I lack the experience and the
hardware to test it. If anyone is interested on implementing this let me
know.
