Within our hosted docs, we are missing documentation for quite a lot of
settings - sometimes for newer settings, sometimes for settings that are
more than two years old. This leads (amongst other things) to feature
requests for features that are already supported, false issue reports
(because people couldn't find the setting for what caused the issue
within the documentation) and generally just takes time for for both
these affected by the missing documentation as well as these handling
the questions around it.

This change here takes a stab at the problem by adding more
documentation for a lot supported setting (not all of it) as well as
reorganizing some settings so that some stuff can (hopefully) be found
more easily. Eventually, we should find a better method for this, but
it's still better than informing people for the n-th time that we e.g.
have `agent_font_size` for the agent panel. Manually audited twice but
I'll take another thorough look before merging.

Closes #36938

Follow up to https://github.com/zed-industries/zed/pull/36554

When `registerOptions` is `None`, we should fall back instead of
skipping capability registration.

1. `Option<OneOf<bool, T>>`, where `T` is struct – handled in the
attached PR ✅
2. `Option<T>`, where `T` is an enum that can be `Simple(bool)` or
`Options(S)` – this PR ✅
3. `Option<T>`, where `T` is struct – we should fall back to default
values for these options ⚠️

Release Notes:

- Fixed an issue where hover popovers would not appear in language
servers like Java.

Closes https://github.com/zed-industries/zed/issues/33725

The default bindings for the `editor::NewlineAbove` and
`editor::NewlineBelow` actions in the default keymap were accidentally
swapped some time ago. This causes confusion, as normally these are the
other way around.

This PR fixes this by swapping these back, which also matches what
[VSCode does by
default](https://code.visualstudio.com/shortcuts/keyboard-shortcuts-linux.pdf).

Release Notes:

- Swapped the default bindings for `editor::NewlineBelow` and
`editor::NewlineAbove` for Linux and Windows to align more with other
editors.

- **Pass --engine-strict to gemini install command**
- **Make it clearer that if upgrading fails, you need to fix i**

Closes #36300

This PR follows Windows conventions by introducing
`KeybindingKeystroke`, so shortcuts now show up as `ctrl-shift-4`
instead of `ctrl-$`.

It also fixes issues with keyboard layouts: when `use_key_equivalents`
is set to true, keys are remapped based on their virtual key codes. For
example, `ctrl-\` on a standard English layout will be mapped to
`ctrl-ё` on a Russian layout.

## Fix: Preserve Helix mode when using  search

### Problem
When using `buffer search: deploy` in Helix mode, pressing Enter to
dismiss the search incorrectly returned to Vim NORMAL mode instead of
Helix NORMAL mode.

### Root Cause
The `search_deploy` function was resetting the entire `SearchState` to
default values when buffer search: deploy was activated. Since the
default `Mode` is `Normal`, this caused `prior_mode` to be set to Vim's
Normal mode regardless of the actual mode before search.

### Solution
Modified `search_deploy` to preserve the current mode when resetting
search state:
- Store the current mode before resetting
- Reset search state to default
- Restore the saved mode to `prior_mode`

This ensures the editor returns to the correct mode (Helix NORMAL or Vim
NORMAL) after dismissing buffer search.

### Settings

I was able to reproduce and then test the fix was successful with the
following config and have also tested with vim: default_mode commented
out to ensure that's not influencing the mode selection flow:

```
  "helix_mode": true,
  "vim_mode": true,
  "vim": {
    "default_mode": "helix_normal"
  },
```

This is on Kubuntu 24.04.

The following test combinations pass locally:

- `cargo test -p search`
- `cargo test -p vim` 
- `cargo test -p editor`
- `cargo test -p workspace`
- `cargo test -p gpui -- vim`
- `cargo test -p gpui -- helix`

Release Notes:

- Fixed Helix mode switching to Vim normal mode after using `buffer
search: deploy` to search

Closes https://github.com/zed-industries/zed/issues/29746

| Action | New Key | Old Key | Former Conflict |
| - | - | - | - |
| `edit_prediction::ToggleMenu` | `ctrl-alt-shift-i` | `ctrl-shift-i` |
`editor::Format` |
| `editor::ToggleEditPrediction` | `ctrl-alt-shift-e` | `ctrl-shift-e` |
`project_panel::ToggleFocus` |

These aren't great keys and I'm open to alternate suggestions, but the
will work out of the box without conflict.

Support to show diagnostics on the tab switcher in the same way they are
displayed on the tab bar. This follows the setting
`tabs.show_diagnostics`.

This will improve user experience when disabling the tab bar and still
