## Why
Selecting the first matching session name can target the wrong conversation when labels are duplicated. Session commands also need to accept preview text when no explicit name is set.
## What changed
- Share app-server label lookup across resume, fork, archive, unarchive, delete, and queue commands, matching the trimmed name or fallback preview.
- Reject distinct matching sessions across collections and source filters, and require a UUID when pagination prevents verifying uniqueness.
- Revalidate listed candidates with `thread/read`, skip unusable local rollouts, and retain compatibility with older servers that cannot read unloaded threads.
- Show ambiguous resume errors in the TUI without replacing the current conversation.
- Disable implicit local daemon reuse with `--oss`.
## Testing
Add regression coverage for name and preview lookup, provider filtering, duplicate labels across pages and collections, stale rollouts, older-server compatibility, queue ambiguity, and preserving the current conversation after an ambiguous resume.
