This PR allows expanding the message editor textarea to fit almost the
total height of the Agent Panel. Stylistically, I'm also changing the
font family we use in the textarea to use the buffer font; want to
experiment with this for a bit.

Release Notes:

- agent: The Agent Panel textarea can now be expanded to fill almost the
total height of the panel.

This PR lightly refactors the `EditorMode::Full` exposing two new
methods: `is_full` and `set_mode`.

Motivation is to expose fields that modify the behavior when the editor
is in `Full` mode. By using is `mode.is_full()` instead of
`EditorMode::Full` we can introduce new fields without breaking other
places in the code.

This PR fixes usage of non-streaming Copilot Chat models.

Closes https://github.com/zed-industries/zed/issues/28528.

Release Notes:

- Fixed an issue with using non-streaming Copilot Chat models (e.g., o1,
o3-mini).

This PR introduces support for a `--user-data-dir` CLI flag to override
Zed's data directory and proposes renaming `support_dir` to `data_dir`
for better cross-platform clarity. It builds on the discussion in #25349
about custom data directories, aiming to provide a flexible
cross-platform solution.

### Changes

The PR is split into two commits:
1. **[feat(cli): add --user-data-dir to override data
directory](https://github.com/zed-industries/zed/pull/26886/commits/28e8889105847401e783d1739722d0998459fe5a)**
2. **[refactor(paths): rename support_dir to data_dir for cross-platform
clarity](https://github.com/zed-industries/zed/pull/26886/commits/affd2fc606b39af1b25432a688a9006229a8fc3a)**


### Context
Inspired by the need for custom data directories discussed in #25349,
this PR provides an immediate implementation in the first commit, while
the second commit suggests a naming improvement for broader appeal.
@mikayla-maki, I’d appreciate your feedback, especially on the rename
proposal, given your involvement in the original discussion!

### Testing
- `cargo build `
- `./target/debug/zed --user-data-dir ~/custom-data-dir`

Release Notes:
- Added --user-data-dir CLI flag

Motivation for this change is to use `ContextStore` in headless
assistant, which requires it to not depend on UI entities like
`Workspace`.

This reapplies a change that was revert was in #28428, and fixes the panic.

Release Notes:

- N/A

Release Notes:

- The agent panel's regex search tool is now optionally case-sensitive.

This reverts commit f12a554f86fa1e2b9b937a9dd103aa7c9a019db9, which
introduced a panic in inline assistant (cc @mgsloan) - I'm not sure what
the motivation was for that change, but I figure we can revert to fix
the inline assistant now and deal with that later. 😄

Panic was:

> Thread "main" panicked with "cannot read workspace::Workspace while it
is already being updated" at
/Users/rtfeldman/code/zed/crates/gpui/src/app/entity_map.rs:139:32


Release Notes:

Trying out sending the model a reminder message about code blocks in the
system prompt. If this seems to work well, we can include more specific
reminder messages, e.g. tool-specific ones.

A small addition for those coming from JetBrain's IDEs. A behavioral
detail: when any upper case character is detected, the command defaults
to toggling to lower case.

> Note that when you apply the toggle case action to the CamelCase name
format, IntelliJ IDEA converts the name to the lower case.


https://www.jetbrains.com/help/idea/working-with-source-code.html#edit_code_fragments

Release Notes:

- Added an `editor: toggle case` command. Use `cmd-shift-u` for macOS
and `ctrl-shift-u` for Linux, when using the `JetBrains` keymap.
