TUI "Move session" picker can't reach nested project directories; Search returns "No results found" #49212

Summary

The TUI Move session picker (/move — "Move to another project dir") only lists a shallow set of directories and cannot reach nested project directories the server already knows about. Searching for the nested project returns "No results found", and ctrl+m ("new") exits to the new-session screen instead of offering to add a path.

Reproduction

1. Have sessions in two directories, e.g. /work and /work/repos/HomeLab, where /work/repos/HomeLab is a registered project — it appears in the server's project / project_directory tables and in GET /session.
2. Attach a TUI whose session lives in /work.
3. Run /move (command palette: Move session, desc. "Move to another project dir").
4. The picker lists only /work and /work/repos. /work/repos/HomeLab is not listed.
5. Type HomeLab in the Search box → "No results found".
6. Press ctrl+m ("new") → returns to the new-session screen; it does not offer to add/enter a directory path.

Expected

• The picker should surface registered project directories, including nested ones (/work/repos/HomeLab).
• Search should match nested projects.
• There should be a way to enter an arbitrary directory path to move to — the footer advertises new ctrl+m, but it does not add a path here.

Notes

• Directory-scoped session listing is expected (sessions in other directories don't appear). The problem is specifically that Move session cannot reach a valid target directory, so there is no in-app way to move a session into a nested project.
• Workaround: launch/attach with --dir /work/repos/HomeLab (or -s <sessionID>), or use the web UI.
• --dir / -s on attach do work, so this is scoped to the in-app picker.

Version

• opencode 1.18.30 (/usr/local/bin/opencode)
• Server: opencode web --port 4096 --hostname 0.0.0.0 on Linux; sessions created via the web UI and attached to from the CLI.
