This PR removes the retained `MarkdownStyle` on the `Markdown` entity in
favor of using the `MarkdownElement` directly and passing the
`MarkdownStyle` to it.

This makes it so switching themes will be reflected live in the code
block styles.

I wanted this for CONL (https://conl.dev )'s nascent langauge server,

side, so this surfaces it into the editor.

With #27295, the cursor would center upon running
`SelectLargerSyntaxNode`. This was done to provide more context when
making large selections, but when making small selections (such as a
single parameter in an argument list) it was confusing that the scroll
position jumped.

This change makes that behavior slightly more conservative: now when the
selection is small enough to fit on the screen scrolling will only occur
to keep the cursor position on the screen (including respecting
`vertical_scroll_margin`).

I found a few more cases where the UI wasn't updated immediately after
an interaction.

Release Notes:

- agent: Fixed delay after removing threads from "Past Interactions"
- agent: Fixed delay after adding/remove context via keyboard

Release Notes:

- Agent Beta: Fixed a delay when sending the first message in a new
thread

Currently, it's pretty common that when the agent gets stuck, it deletes
whatever it's stuck on and replaces it with a TODO comment, then
cheerfully reports that it has "simpified" the implementation. This is
worse than leaving the broken code, because at least a human could take
over and try to get it across the finish line.

This system prompt adjustment attempts to make the agent do something
more useful when in this situation: report that it's stuck, explain why
it's stuck, and ask the user what to do.

Release Notes:

- The `read_files` tool now reads only the symbol outline files above a
certain size, to conserve context window space. Then it suggests that
the agent call `read_files` again with the relevant line ranges it saw
in the outline.

This PR reverts #27897, as it is causing a number of Helix-related tests
to fail:

```
     Summary [  84.324s] 1796 tests run: 1793 passed, 3 failed, 0 skipped
        FAIL [   0.434s] vim helix::test::test_delete

        FAIL [   0.537s] vim helix::test::test_delete_character_end_of_line
```

This reverts commit 9949512b64ab2f472fc3426d853bc9bd0f6d94e2.

Release Notes:

- Community: Reverted https://github.com/zed-industries/zed/pull/27897.

This adds a `next_mode` parameter to the `vim::Paste` action. My main
use-case for this is for helix users, who will want to switch into
`HelixNormal` mode instead of `Normal` mode.

I'm not sure if this is the best approach -- another possibility would
be to have a global vim-vs-helix configuration, and then have every
invocation of "normal" mode choose vim or helix based on that global
configuration. But the approach in this PR is much less invasive.

Release Notes:

- vim: switch to the configured default mode after paste instead of
hard-coding Normal mode

This bumps `wasi-sdk` to version 25 and adds target architecture
conditionals.

Closes #18492

Release Notes:

- Fixed compiling dev extensions with Tree-sitter grammars on Linux
aarch64.

This PR fixes the `assistant: open prompt library` action in the command
palette not opening the prompt library when the Assistant Panel did not
have focus.

Fixes https://github.com/zed-industries/zed/issues/28058.

Release Notes:

- assistant: Fixed `assistant: open prompt library` not opening the
prompt library when the Assistant Panel was not focused.

This PR fixes an issue where opening the configuration view from the
model selector in the Agent (or inline assist) was not working properly.

Fixes https://github.com/zed-industries/zed/issues/28078.

Release Notes:

- Agent Beta: Fixed an issue where selecting "Configure" in the model
selector would not bring up the configuration view.

Closes #27223
Merges: #27996, #26734, #27949 

Release Notes:

- AWS Bedrock: Added advanced authentication strategies with:
  - Short lived credentials with Session Tokens 
  - AWS Named Profile
  - EC2 Identity, Pod Identity, Web Identity
- AWS Bedrock: Added Claude 3.7 Thinking support.
- AWS Bedrock: Adding Cross Region Inference for all combinations of
regions and model availability.
- Agent Beta: Added support for AWS Bedrock.

A user reported this issue [on
Discord](https://discord.com/channels/869392257814519848/873292398204170290/1357879959422636185).

The issue here only arises for users which recently installed Zed or had
previously not dismissed the Git Onboarding component. It was introduced
by https://github.com/zed-industries/zed/pull/27412, which made the
banner component reusable.

For every banner, there is a value stored in the KVP store when it was
first dismissed. For the git onboarding banner, this was
`zed_git_banner_dismissed_at` initially, but this key would have been
changed by the linked PR. A change would have resulted in the banner
being shown again for users who already dismissed the panel, so for the
special case of `Git Onboarding`, a check was added which ensured this
would not happen.

However, this check was only added for reading from the key from the DB
but not on writing the git onboarding dismissal it to the DB. Thus, if a
user who had not previously dismissed the panel opened Zed, we would
check for the old key to be present in the DB. Since that would not be
the case, the banner would be shown. If the user dismissed the panel, it
would be stored in the database with the new key. Thus, on a reopen of
Zed, the banner would again be shown since for the old key there would
still be no value present and users are unable to dismiss the panel.


This PR fixes this behavior by moving the check into the method that
generates the key. With this, users which were unaffected by the bug
will still not see the panel again. Users who would install Zed with
this change present will be able to properly dismiss the panel aswell.
Users which were affected by the bug need to dismiss the banner one more
time. That happens because I did not want to modify the dismissal check
to check for two keys (the original one and the new one), as it would
clutter the logic even more for this special case. If this would be
preferred, feel free to let me know.

Release Notes:

- Fixed an issue where dismissing the git onboarding banner would not be
persisted across sessions.

Tool use output wouldn't get rendered in some states.

Closes #26907

Currently, in case of new line to find delta, it is comparing old first
line indent with new second line indent. This results into incorrect
indentation. This PR fixes this delta calculation by passing correct
second line indent in that particular case.

Release Notes:

- Fixed issue where pasting code starting with new line resulted
incorrect auto indent.

A "Near" block acts similarly to a "Below" block, but can (if it's
height is <= one line height) be shown on the end of the preceding line
instead of adding an entire blank line to the editor.

You can test it out by pasting this into `go_to_diagnostic_impl` and
then press `F8`
```
        let buffer = self.buffer.read(cx).snapshot(cx);
        let selection = self.selections.newest_anchor();

PR #24388 changed the markdown parsing to copy parsed text in order to
handle markdown escaping, removing the optimization to instead reuse
text from the input.

Another issue with that change was that handling of finding links within
`Text` intermixed use of `text` and `parsed`, relying on the offsets
matching up (which I believe was true in practice).

The solution is to distinguish pulldown_cmark `Text` nodes that share
bytes with the input and those that do not.

This PR fixes a panic that could occur when opening the Agent diff from

Seems to be very similar to
https://github.com/zed-industries/zed/pull/28059

Edit: Updated the reproduction-steps as I missed something.

The method without a check currently causes my debug-builds to crash on
the regular if I:
- Run a debug build and open it fullscreen in a dedicated space on my
Mac.
- Work on any of the built-in languages (e.g. remove some content from
any `highlights.scm`)
- Reopen the workspace with the debug-build.
- Crash.

~~We might actually be able to revert the changes made in
https://github.com/zed-industries/zed/pull/21510 and just add the
null-check. Then again, I am not at all sure whether that would work.­~~
