Closes#32354
The issue is that we render selections over the text in the agent panel,
but under the text in editor, so themes that have no alpha for the
selection background color (defaults to 0xff) will just occlude the
selected region. Making the selection render under the text in markdown
would be a significant (and complicated) refactor, as selections can
cross element boundaries (i.e. spanning code block and a header after
the code block).
The solution is to add a new highlight to themes
`element_selection_background` that defaults to the local players
selection background with an alpha of 0.25 (roughly equal to 0x3D which
is the alpha we use for selection backgrounds in default themes) if the
alpha of the local players selection is 1.0. The idea here is to give
theme authors more control over how the selections look outside of
editor, as in the agent panel specifically, the background color is
different, so while an alpha of 0.25 looks acceptable, a different color
would likely be better.

Clearly, the selection in the after doesn't look _that_ great, but it is
better than the before, and this PR makes the color of the selection
configurable by the theme so that this theme author could make it a
lighter color for better contrast.
Release Notes:
- agent panel: Fixed an issue with some themes where selections inside
the agent panel would occlude the selected text completely

Now we:
* Automatically retry up to 3 times on upstream Overloaded or 500 errors
(currently for Anthropic only; will add others in future PRs)
* Also automatically retry on rate limit errors (using the provided
duration to wait, if we were given one)
* Give you a notification if you don't have Zed open and we stopped the
thread because of an error
Still todo in future PRs:
* Update collab to report Overloaded and 500 errors differently if
collab itself is passing through an upstream error vs not (currently we
report these as "Zed's API is overloaded" when actually it's the
upstream one!)
* Updating providers other than Anthropic to categorize their errors so
that they benefit from this
* Expanding graceful error handling/retry to other things besides
Overloaded and 500 errors (e.g. connection reset)
Release Notes:
- Automatically retry in Agent Panel instead of erroring out when an
upstream AI API is overloaded or 500s
- Show a notification when an Agent thread errors out and Zed is not the
active window
While working on retries, I discovered some opportunities to reduce
cloning of message segments. These segments have full `String`s (not
`SharedString`s), so cloning them means copying cloning all the bytes of
all the strings in the message, which would be nice to avoid!
Release Notes:
- N/A
This PR moves the UI-dependent logic in the `agent` crate into its own
crate, `agent_ui`. The remaining `agent` crate no longer depends on
`editor`, `picker`, `ui`, `workspace`, etc.
This has compile time benefits, but the main motivation is to isolate
our core agentic logic, so that we can make agents more
pluggable/configurable.
