Restarting `claude rc` cannot continue a session that was cut off in the mobile app

Follow-up to #68606, which the stale bot closed with "open a new issue if this is still relevant."

What happened

I was driving claude rc on my own machine from the Claude mobile app. The machine died mid-session. After it came back I ran claude rc in the same repository and reconnected from the app — and there was no way to continue the session I had been working in. A fresh session was created instead. The mobile app offered nothing to reattach to.

The work was not lost — the transcripts were on disk the whole time — but nothing in the CLI or the app leads you to them.

Why the existing ask does not cover this

#68606 asks for the session list to rehydrate from on-disk transcripts for the server's cwd. That would not have helped: the sessions were never filed under the server's cwd.

claude rc spawns each session into <repo>/.claude/worktrees/bridge-cse_<session-id>/, and that worktree path becomes the session's project key:

~/.claude/projects/<repo>/                                  ← the server's cwd
~/.claude/projects/<repo>--claude-worktrees-bridge-cse-…/   ← where the transcript is

Nothing in the cwd's project directory points at them — bridge-pointer.json names only the newly created session. There is no mapping on disk, in either direction, between the repository I ran claude rc in and the sessions it spawned.

Repro

1. claude rc in a git repository; start a session from the mobile app and do some work.
2. Kill the host or the claude rc process.
3. Restart and run claude rc in the same repository; reconnect from the app.

The interrupted session cannot be continued from either side, and a fresh one is created.

Ask

Restarting claude rc should offer the sessions it previously spawned for that directory. Extending #68606's fix to cover <dir>/.claude/worktrees/*, or having the spawning directory record where it put the session, would do it.

Environment

Claude Code 2.1.232, Linux (WSL2), claude rc server mode driven from the mobile app.
