Nathan Sobo 270eb87673 agent_ui: Reuse visible sessions when reopening threads (#53905)
When reopening a thread that is already visible in the agent panel,
`open_thread` could recreate the session instead of reusing the existing
visible thread. That left the UI holding a thread whose backend session
could be closed out from under it.

This change routes `AgentPanel::open_thread` through
`load_agent_thread`, which already handles the right behavior for
existing sessions:
- reuse the active thread when it already matches
- promote a retained thread when it matches
- only load when the session is not already present

The regression coverage is now a focused behavioral test at the
`AgentPanel::open_thread` boundary that verifies reopening an
already-visible session keeps the thread usable.

Release Notes:

- Fixed reopening an already-visible agent thread so it reuses the
existing session instead of creating a broken duplicate.

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.
