Cherry-picked keymap_ui: Additional keystroke input polish (#35208)

Closes #ISSUE

Fixed various issues and improved UX around the keystroke input
primarily when used for keystroke search.

Release Notes:

- Keymap Editor: FIxed an issue where the modifiers used to activate
keystroke search would appear in the keystroke search
- Keymap Editor: Made it possible to search for repeat modifiers, such
as a binding with `cmd-shift cmd`
- Keymap Editor: Made keystroke search matches match based on ordered
(not necessarily contiguous) runs. For example, searching for `cmd
shift-j` will match `cmd-k cmd-shift-j alt-q` and `cmd-i g shift-j` but
not `alt-k shift-j` or `cmd-k alt-j`
- Keymap Editor: Fixed the clear keystrokes binding (`delete` by
default) not working in the keystroke input

In project panel, `rename` and `duplicate` action further needs user
input for editing, so if panel is closed we should open it.

Release Notes:

- Fixed project panel not opening when `project panel: rename` and
`project panel: duplicate` actions are triggered from workspace.

Someone encountered this in production, which should not happen:

<img width="1266" height="623" alt="Screenshot 2025-07-24 at 10 38

src="https://github.com/user-attachments/assets/40f3f977-5110-4808-a456-7e708d953b3b"
/>

This moves certain errors into the category of "never retry" and reduces
the number of retries for some others. Also it adds some diagnostic
logging for retry policy.

It's not a complete fix for the above, because the underlying issues is
that the server is sending a HTTP 403 response and although we were
already treating 403s as "do not retry" it was deciding to retry with 2
attempts anyway. So further debugging is needed to figure out why it
wasn't going down the 403 branch by the time the request got here.

There were two different underlying reasons for the issues with
ctrl-number and ctrl-punctuation:

1. Some keys in the ctrl-0..9 range send codes in the `\1b`..`\1f`
range. For example, `ctrl-2` sends keycode for `ctrl-[` (0x1b), but we
want to map it to `2`, not to `[`.

2. `ctrl-[` and four other ctrl-punctuation were incorrectly mapped,
since the expected conversion is by adding 0x40

sources.

Release Notes:

- N/A

This PR adds resizable columns to the keymap editor and the ability to
double-click on a resizable column to set a column back to its default
size.

The table uses a column's width to calculate what position it should be
laid out at. So `column[i]` x position is calculated by the summation of
`column[..i]`. When resizing `column[i]`, `column[i+1]`’s size is
adjusted to keep all columns’ relative positions the same. If
`column[i+1]` is at its minimum size, we keep seeking to the right to
find a column with space left to take.

An improvement to resizing behavior and double-clicking could be made by
checking both column ranges `0..i-1` and `i+1..COLS`, since only one
range of columns is checked for resize capacity.

As suggested in https://github.com/zed-industries/zed/pull/34418, this
proposes various changes to language configs to make block comments and
doc-block-style comments more similar. In doing so, it introduces some
breaking changes into the extension schema.

This change is needed to support the changes I'm working on in #34418,
to be able to support `rewrap` in block comments like `/* really long
comment ... */`. As is, we can do this in C-style doc-block comments (eg
`/** ... */`) because of the config in `documentation`, but we can't do
this in regular block comments because we lack the info about what the
line prefix and indentation should be.

And while I was here, I did various other clean-ups, many of which feel
nice but are optional.

I would love special attention on the changes to the schema, version and
related changes; I'm totally unfamiliar with that part of Zed.

**Summary of changes**
- break: changes type of `block_comment` to same type as
`documentation_comment` (**this is the important change**)
- break: rename `documentation` to `documentation_comment` (optional,
but improves consistency w/ `line_comments` and `block_comment`)
- break/refactor?: removes some whitespace in the declaration of
`block_comment` delimiters (optional, may break things, need input; some
langs had no spaces, others did)
- refactor: change `tab_size` from `NonZeroU32` to just a `u32` (some
block comments don't seem to need/want indent past the initial
delimiter, so we need this be 0 sometimes)
- refactor: moves the `documentation_comment` declarations to appear
next to `block_comment`, rearranges the order of the fields in the TOML
for `documentation_comment`, rename backing `struct` (all optional)

**Future scope**
I believe that this will also allow us to extend regular block comments
on newline – as we do doc-block comments – but I haven't looked into
this yet. (eg, in JS try pressing enter in both of these: `/* */` and
`/** */`; the latter should extend w/ a `*` prefixed line, while the
former does not.)

Release Notes:

- BREAKING CHANGE: update extension schema version from 1 to 2, change
format of `block_comment` and rename `documentation_comment`

Change channel reorganization (move up/down) from `cmd-up/down` (mac) /
`ctrl-up/down` (linux) to `alt-up/down` (both) to match moving lines in
the editor.

Also fix an issue where if you selected channels using down/up in the
filter field, the movement shortcuts would not work (`editing` vs
`not_editing`).

Quick follow up to #34896 which ensures that the Agent Panel cannot be
caught by actions like `workspace: toggle left dock` when `disable_ai`

Also removes a method that was introduced but unused in the workspace
because `first_enabled_panel_idx` already covers all cases this method
could be useful for.

This PR adds `editor: diff clipboard with selection` - good for spotting
the differences in eerily-similar code, which is when refactoring code,
as you need to see what needs to be passed in in order to maintain
previous behavior of both snippets.

1. Copy some text from anywhere
2. Highlight some text in Zed
3. Run `editor: diff clipboard with selection`

Like JetBrains' IDEs and VS Code with the `PartialDiff` package, if the
selection is empty, we take the entire buffer as the selection.

Caveats:

- We do not know the language of the text in the clipboard. I went ahead
and just assumed that in most cases, it will be the same language as the
selected text, which does mean we will highlight the old text
incorrectly if they are copying from a different language, but I think
in most cases, it will be the same, and the alternative of always having
no syntax highlighting is worse. PyCharm seems to do the same thing.

Release Notes:

- Added an `editor: diff clipboard with selection` action

Closes #7759

While opening a new SSH project if we are reusing an existing window,
i.e. drop the existing workspace and create a new one, then before
dropping it, we should remove `session_id` from that workspace's
serialized entry. That way:

1. Upon closing (cmd-w) this remote workspace (which also clears
`session_id` for this), and then quitting. No workspace with that
`session_id` is found, and it starts fresh.
2. Upon directly quitting (cmd-q) this remote workspace, only this
workspace exists in db (among two of them) with that `session_id`, and
it restores correctly.
 
Release Notes:

- Fixed an issue while closing remote workspace restores last local
workspace on startup.

Closes #34924

Now, when `local_paths` are empty, we detach `session_id` from that
workspace serialization item. This way, when we restore it using the
default "last_session", we don't restore this workspace back. This is
same as when we use `cmd-w` to close window, which also sets
`session_id` to `None` before serialization.

Release Notes:

- Fixed an issue where last removed folder from workspace used to reopen
on Zed startup.

This PR removes the `POST /billing/subscriptions` endpoint, as it has
been moved to `cloud.zed.dev`.
