[FEATURE] Let me find and resume Remote Control sessions locally: show them in /resume and add `claude rc list-sessions`

Summary

When I run claude rc on my computer and start a session from my phone, I can never find that session again on the computer. /resume and claude --resume don't list it, and there is no command that does. The transcript is saved locally like any other session — the picker just hides it, and there's no way to look up its ID.

Proposed fix: show these sessions in /resume (marked as Remote Control sessions), and add claude rc list-sessions (or similar) that prints the local session ID, name, directory and first prompt, so claude --resume <id> / claude rc --session-id <id> become usable.

Problem Statement

Sessions that the Remote Control server spawns for a phone/web client are written to ~/.claude/projects/<project>/<uuid>.jsonl with "entrypoint":"sdk-cli". The resume picker filters every such session out. claude --resume --debug-file … confirms it:

Session ed9f1863-… filtered from /resume: entrypoint=sdk-cli
Session dcf41b86-… filtered from /resume: entrypoint=sdk-cli
Session 5f0da884-… filtered from /resume: entrypoint=sdk-cli

Consequences:

• /resume, claude --resume and Ctrl+A ("all projects") never show them — the same filter runs on every entry.
• claude rc -c only works for the last session and only for ~4 h.
• claude rc --session-id <id> and claude --resume <id> work, but nothing prints the ID. claude.ai/code lists the sessions but its URL uses a different id (session_01K…), not the local UUID.
• The only mapping is ~/.claude/sessions/<pid>.json (sessionId ↔ bridgeSessionId), which is deleted when the process exits.

Today the workaround is grepping transcripts for "entrypoint":"sdk-cli" — not something a user should have to know.

Proposed Solution

1. /resume and claude --resume: include sdk-cli sessions that were created by claude remote-control (they carry a bridgeSessionId), with a marker such as · remote in the row. If hiding headless SDK sessions is intentional for other SDK uses, scope the exemption to Remote Control-spawned ones.
2. claude rc list-sessions (or claude rc --list): print local session ID, session name (e.g. my-repo-26), cwd, status (if running), last modified, first prompt — for the current directory by default, --all for every project. Output should be usable directly with claude --resume <id> and claude rc --session-id <id>.

Alternative Solutions

• A flag claude --resume --include-remote / --all-entrypoints if changing the default is undesirable.
• Show the local session UUID somewhere in claude.ai/code / the mobile app.

Environment

Claude Code 2.1.270 (also seen on 2.1.269), Linux, claude rc with default --spawn same-dir.
