Cherry-picked Revert "Rework hunk controls (#24814)" (#25174)

This reverts commit a6a8d79d8612425dff6ad02dcc14ef99cfdf914e.

Closes #ISSUE

Release Notes:

- Revert incomplete change to diff hunk controls

Co-authored-by: Cole Miller <cole@zed.dev>

Release Notes:

- Fixed a panic in the file finder

When selecting text, it highlights all matching occurences along with
selected text itself. This causes highlight overlap, which looks bit
odd. This PR fixes it.

Bonus:

Context: We have an edge case (which we already cover) where we don’t
want to clear `SelectedTextHighlight` every time the selection changes.
This happens when you are dragging the selection across some word, if
you clear it directly on selection change, due to debounce wait, the
highlight take some time to appear, which causes flickering for the
user. We solve this by not clearing it directly but only clearing it
when a new selection is found. This avoids the flicker.

However, we also need to clear the selection even before the debounce
wait if we detect early on that the selection is different from previous
ones. Otherwise, the user will have to wait until the debounce time to
see it cleared on the screen.

The code for this is a little repetitive because we check the buffer
state both before and after the debounce. But this is necessary.

---
Before:

Notice overlapping corners and selected text is bit darker in this case.

Closes #16951

Handle the case where you click on the terminal while pressing Shift. 

Instead of setting a new selection head, we simply update the selection
to that point. This allows you to repeatedly extend the selection to new
points by pressing Shift while preserving the original selection head.

Preview:

Selection works in direct terminal, but doesn't on Vim like program,
which is expected.

We were highlighting both as `@variable.special` however, they are

This PR fixes an issue where configured language model providers would
not show up unless the configuration view was opened.

The problem was that we were filtering unauthenticated language model
providers out of the language model selector, but would only
authenticate the active provider when the selector loaded.
Authenticating the rest of the providers was deferred until the
configuration view was opened for the first time.

Closes https://github.com/zed-industries/zed/issues/21821.

Release Notes:

- Fixed an issue where configured languages models were not showing up
in the language model selector until the configuration view was opened
for the first time.

This PR updates the `LanguageModelProvider::authenticate` method to
return an `AuthenticateError` instead of an `anyhow::Error`.

This allows us to model the "credentials not found" state explicitly as
`AuthenticateError::CredentialsNotFound`, which enables the caller to
check for this state and act accordingly.

Planning to use this in #25123 to silence errors about missing
credentials when authenticating providers in the background.

and do not fail hard if the editor with the ID given does not exist.
Also add the problematic IDs into the error context to see them in the
error logs.

This PR fixes an issue where the thread history would only work in one
Zed window at a time.

The backing LMDB database can only be opened once per Zed instance.
However, the `ThreadStore` has one instance per Zed window.

To fix this, we need to create the `heed` environment once and store it
as a global, and then reference the same environment across all of the
`ThreadStore`s.

We've decided to go in a different direction on indicating the staged
status of hunks, so go back for now to a world where we don't display
staged and unstaged hunks differently outside the (still gated) project
diff editor.

We begin a columnar selection when we drag the mouse while holding
`alt-shift`. This PR makes it possible to start the selection and then
turn it into columnar by pressing `alt-shift`.

Fixes #5372 

Release Notes:

- Support switching to columnar selection by pressing `alt-shift` while
mouse is down

This PR makes it so we don't log errors for missing themes or icon
themes until after the extensions have been loaded.

Currently, if you are using a theme that is defined in an extension it
is common to see one or more "theme not found" errors in the logs. This
is the result of us having to initialize the theme before the extensions
have actually finished loading.

This means that a theme that _may_ exist once extensions load is
considered non-existent before they have loaded.

To that end, we now wait until the extensions have loaded before we
start logging errors if we can't find the theme or icon theme.

Closes https://github.com/zed-industries/zed/issues/24539.

Release Notes:

- Reduced the number of "theme not found" and "icon theme not found"
errors in the logs for themes provided by extensions.

This PR updates the `ThemeRegistry` to return structured errors from the
`get` and `get_icon_theme` methods (which are used to retrieve themes
and icon themes, respectively).

We want to be able to carry the name of the theme that was not found as
state on the error, which is why we use a `Result` and not an `Option`.
However, we also want to be able to accurately identify when the error
case is "not found" so we can take appropriate action, based on the
circumstances.

By using a custom error type instead of an `anyhow::Error`, we get both.

There isn't any functional change in this PR. This just sets us up for
future improvements in this error.

For symlinks, return `None` from `load_committed_text` as we do from
`load_index_text` ever since #10037.

Release Notes:

- Fixed diff hunks appearing in unchanged symlinked files

This PR makes progress on #7711 by identifying any common prefix of the
paths in the file finder's search results, and replacing the "interior"
of that prefix---every path segment but the first and last---with `...`,
when a heuristic indicates that the longest path would otherwise
overflow the modal.

The elision is not applied to any segment that contains a match for the
search query.

There may be more work to do on #7711 in the case of long result paths
that do not share a significant common prefix.

Release Notes:

- Improved display of long paths in the file finder modal

Release Notes:

- Started to persist latest selections for editors, to restore those on

Super subtle, but when I initially saw just "Close", I got weirded out
asking myself "why there's a menu item to close the context menu?", to
only then realize that it didn't close the menu, but the terminal _tab_.
Might be obvious, because that's how buffer tabs are labled, but I don't
know, it feels like the redundancy here is overall positive.

Some language servers report version 0 even if the buffer hasn't been
opened yet. We detect this case and treat it as if the version was
`None`.
