Cherry-picked project: Workaround invalid code action edits from pyright
(#28354)

Co-authored-by: Max Brunsfeld <maxbrunsfeld@gmail.com>
Co-authored-by: Piotr Osiewicz <piotr@zed.dev>

fixes issue where:

In a two line python file like so
```

Path()
```

If the user asks for code actions on `Path` and they select (`From
pathlib import path`)
the result they get is
```

Pathfrom pathlib import Path


Path()
```
Instead of 

```

from pathlib import Path



Path()
```

This is due to a non-lsp-spec-compliant response from pyright below

```json
{"jsonrpc":"2.0","id":40,"result":[{"title":"from pathlib import Path","edit":{"changes":{"file:///Users/neb/Zed/example-project/pyright-project/main.py":[{"range":{"start":{"line":2,"character":0},"end":{"line":2,"character":4}},"newText":"Path"},{"range":{"start":{"line":2,"character":0},"end":{"line":2,"character":0}},"newText":"from pathlib import Path\n\n\n"}]}},"kind":"quickfix"}]}
```

Release Notes:

- Fixed an issue when using auto-import code actions provided by pyright
(or basedpyright) where the import would be jumbled with the scoped
import resulting in an invalid result

Release Notes:

- Adjusted system prompt to direct it to never act on TODO-type comments
it encounters, unless the user directly asked it to do so or they relate
to the current task at hand.

This also increases the threshold for when we return an outline during
`read_file`.

Release Notes:

- Fixed an issue that caused the agent to fail reading large files if
the LSP hadn't started yet.

Release Notes:

- Adjusted system prompt to direct it to never remove tests as a way to
have the test suite pass, unless the user directly asks for test
removal.

unnecessarily.

Sometimes agents do this. I've had some success responding by telling it

Release Notes:

Release Notes:

- Agent panel now shows links to relevant source code files above code
blocks.

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.

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.

Cherry-picked title_bar: Ensure git onboarding banner dismissal is
properly respected (#28147)

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.

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.

then press `F8`
```
        let buffer = self.buffer.read(cx).snapshot(cx);

Previously, when comparing a block with an empty range to an empty query
range in non-inclusive mode, our binary search logic could end up
computing an inverted range, causing a panic.

This commit adds special casing when comparing empty blocks with empty
ranges.

cc @as-cii: I'm realizing that the approach to searching for the
intersecting replacement blocks makes some invalid assumptions about the
ordering of replace decorations. They aren't ordered at all by their end
range. @maxbrunsfeld and I are wondering if long term, we should remove
replace decorations and find another solution for folding buffers in
multi buffers.
