Handle removed IconName variants in text thread deserialization (#47624)
Fixes #41776

## Problem

Old AI Text Thread sessions fail to open from History because the
deserializer fails on unknown icon variants. When icons are removed or
renamed in refactors, old saved threads become unloadable with errors
like:

```
unknown variant `AtSign`, expected one of `Ai`, `AiAnthropic`...
```

## Solution

Added a lenient deserializer for the `icon` field in
`SlashCommandOutputSection` that falls back to `IconName::Code` for
unknown variants.

This ensures old saved threads remain loadable even as icons are
added/removed from the codebase.

## Test Plan

- Added unit test for valid icon deserialization
- Added unit test for unknown icon fallback to `Code`
- Added unit test for various unknown icon variants
- Added unit test confirming serialization unchanged
- All tests pass: `cargo test -p assistant_slash_command`

Release Notes:

- Fixed old AI text thread sessions failing to open from History when
they contain icons that were removed in previous updates.

Licensing

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
