fixes https://github.com/zed-industries/community/issues/432

Release Notes:

- Added support for the svelte language

Bump scheme dependency:

Add svelte tree sitter
Add svelte config file
Add svelte highlighting

I'm a bit tired of the complaining for this feature. But also, we should
have it. Hence, this PR.

fixes:
https://github.com/zed-industries/community/issues/304#issue-1305112032

Release Notes:
- Added a `buffer_line_height` setting

We're finally doing the thing. 


TODO:
- [x] Choose an approach 
- Decided to add a new element just for the pane axis, containing a
slimmed down copy of the flex code.
- [x] Wire through callbacks and pointers so that data goes where it
needs to
- [x] Do the flex juggling math on resize
- [x] Update the flexes when updating the split tree
- [x] Restore the active_pane_magnification setting
- [x] Serialize an axis' flexes

Release Notes:
- Made the center pane group splits resizable. Note that resizing is
disabled if the `active_pane_magnification` setting is changed from
default.

Follow-up of https://github.com/zed-industries/zed/pull/2713, fixing the
same for the bundling part of the pipeline.

Currently, when converting from LSP to Zed objects, completions with
non-empty `additional_text_edits` are filtered out.
Later, all other completions form a list and the selected one gets the
`Editor::confirm_completion` call, which always queries an LSP
completion resolve request to get the `additional_text_edits` field.

Otherwise, `additional_text_edits` field is ignored entirely for the
rest of the completion lifetime — and we always pass the selected
completion through the resolve request.

The PR changes the logic, removing the `additional_text_edits` filtering
and instead of resolving every completion, now we check for
`additional_text_edits` in the completion before resolving: resolve
happens only if the data is absent.

Generally, feels like resolve has to happen before the completion
selection: LSP servers may send us markdown for completion documentation
preview pop ups and similar extra info.
Also, the server may lack resolve capabilities entirely, always sending
the request seems dangerous.
For now, the PR does not attempt to change either.

Release Notes:

- Brings rust-analyzer's postfix completions and others completions with
preresolved additional text edits

Update docs

This PR includes a new crate, aimed at maintaining a consistent semantic
embedding database, for any project opened with Zed. At a high level,
for each file in a project, we parse the file with treesitter, embed the
symbol "document" objects with OpenAI, and maintain a consistent
database of these embeddings and offset locations in a sqlite database.
Once stored, we have built a simple modal interface for querying on
these symbols embeddings using natural language, offering the
opportunity to navigate to the selected symbol.

This initial PR is intended to provide this functionality only in preview,
as we explore, evaluate and iterate on the vector store.

Also makes it match the contacts button and seems to more closely
resemble the mockups as far as I can tell

Release Notes:

- Fixed the titlebar user menu button obscuring part of the border below
it.

This removes transitive dependency on libnghttp2, which is pretty heavy.

Kevin Hovsäter reported a crash in cli when running 'cargo run -p cli --
--bundle-path target/debug/Zed'. It was caused by unaligned pointer
access in ipc-channel library; rustc started generating debug_asserts
for pointer alignment starting with 1.70, which we have
oh-so-conveniently upgraded to shortly before Kevin noticed a crash.
Rust 1.70 did not introduce this panic, it merely started triggering on
UB that was previously ignored.

Match highlighting for recent projects picker was off, because the path
representation was compacted - for a path '/Users/hiro/Projects/zed' we
compact it to use a tilde instead of home directory. However, the
highlight positions were always calculated for a full path, leading to a
mismatch in highlights. This commit addresses this by running fuzzy
search on compacted paths instead of using long paths. This might lead
to a slight performance hit, but given that recent projects modal
shouldn't have that many items in the first place, it should be okay.

Release Notes:

- Fixed result highlighting in "Recent projects" modal.
