Before we were always reading the entire file into memory as a string.
Now we only read the range that is actually requested.

Release Notes:

- N/A *or* Added/Fixed/Improved ...

We were incorrectly handling the line number as well as stripping out
line breaks when returning portions of files.

It also makes sure following is updated even when we load a snapshot
from cache, which wasn't the case before.

We also are able to load the text via a range in the snapshot, rather
than allocating a string for the entire file and then another after
iterating over lines in the file.

Release Notes:

- acp: Fix incorrect behavior when ACP agents requested to read portions
of files.

Closes #34192

Without selection, only current character would be affected.

Also if #38117 is merged too, then transformations in SelectMode behave
correctly too and selection is not collapsed.

Release Notes:

- helix: Implemented `~`, `` ` ``, `` Alt-` `` correctly in normal and
select modes

Closes #38304 

Release Notes:

- Fixed true color detection regression by setting `COLORTERM=truecolor`

---

Reason:

The regression is possibly introduced in [pr#36576: Inject venv
environment via the
toolchain](https://github.com/zed-industries/zed/pull/36576/files#diff-6f30387876b79f1de44f8193401d6c8fb49a2156479c4f2e32bc922ec5d54d76),
where `alacritty_terminal::tty::setup_env();` is removed.

The `alacritty_terminal::tty::setup_env();` does 2 things, which sets
`TERM` & `COLORTERM` envvar.
```rs
/// Setup environment variables.
pub fn setup_env() {
    // Default to 'alacritty' terminfo if it is available, otherwise
    // default to 'xterm-256color'. May be overridden by user's config
    // below.
    let terminfo = if terminfo_exists("alacritty") { "alacritty" } else { "xterm-256color" };
    unsafe { env::set_var("TERM", terminfo) };

    // Advertise 24-bit color support.
    unsafe { env::set_var("COLORTERM", "truecolor") };
}
```

Tests that the downstream project can see custom agents configured in
the remote server's settings, and that it constructs an appropriate
`AgentServerCommand`.

Release Notes:

- N/A

In local projects, initialize the list of agents in the agent server
store immediately. Previously we were initializing the list only after a
delay, in an attempt to avoid sending the `ExternalAgentsUpdated`
message to the downstream client (if any) before its handlers were
initialized. But we already have a separate codepath for that situation,
in the `AgentServerStore::shared`, and we can insert the delay in that
place instead.

Release Notes:

- acp: Fixed a bug where starting an external agent thread soon after
Zed starts up would show a "not registered" error.

Closes #11760

The command `project panel: collapse all entries` currently does not
collapse top-level entries (the workspaces themselves). I think this
should be expected behaviour if you only have a single workspace in your
project. However, if you have multiple workspaces, we should collapse
their top-level folders as well. This is the expected behaviour in the
screenshots in #11760.

For more context: Atm the `.retain` function empties the
`self.expanded_dir_ids` Hash Map, because the `expanded_entries` Vec is
(almost) never empty - it contains the id of the `root_entry` of the
workspace.


https://github.com/zed-industries/zed/blob/d48d6a745409a8998998ed59c28493a1aa733ebb/crates/project_panel/src/project_panel.rs#L1148-L1152

We then update the `self.expanded_dir_ids` in the
`update_visible_entries` function, and since the Hash Map is empty, we
execute the `hash_map::Entry::Vacant` arm of the following match
statement.


https://github.com/zed-industries/zed/blob/d48d6a745409a8998998ed59c28493a1aa733ebb/crates/project_panel/src/project_panel.rs#L3062-L3073

This change makes sure that we do not clear the `expanded_dir_ids`
HashMap and always keep the keys for all visible workspaces and
therefore we run the `hash_map::Entry::Occupied` arm, which does not
override the `expanded_dir_ids` anymore.

Bug in https://github.com/zed-industries/zed/pull/32927

Instead of using trigger characters to clear cached completions items,
now we check if the query is empty to clear it. Turns out Emmet defines
whole [alphanumeric as trigger
characters](https://github.com/olrtg/emmet-language-server/blob/279be108725fb391c167690b697ce154fd32657b/index.ts#L116)
which causes flickering.

Clear on trigger characters was introduced to get rid of cached
completions like in the case of "Parent.Foo.Bar", where "." is one of
the trigger characters. This works still since "." is not part of
`completion_query_characters` and hence we use it as a boundary while
building the current query. i.e in this case, the query would be empty
after typing ".", clearing cached completions.

Release Notes:

- Fixed issue where completions menu flashed on every keystroke in TSX
files with emmet extension installed.

The problem from issue #37509 comes from local virtual environments
created with certain approaches (including the 'simple' way of `python
-m venv`) not having a `.project` file with the path to the project's
root directory. When the toolchains are sorted, a virtual environment in
the project is not treated as being for that project and therefore is
not prioritized.

With this change, if a toolchain does not have a `project` associated
with it, we check to see if it is a virtual environment, and if it is we
use its parent directory as the `project`. This will make it the top
priority (i.e. the default) if there are no other virtual environments
for a project, which is what should be expected.

Closes #37509

Release Notes:

- Improved python toolchain prioritization of local virtual
environments.

My pre push hooks keep failing on these. This is easier then disabling
and re-enabling those hooks all the time :)
