docs(adopt): add the frontend note and scan the module for CLI ids

foreign-sessions.js joins the files the no-id test scans, so the catalog lookup
stays one. The block's rules go where a frontend reader looks, in
src/web/CLAUDE.md, and the architecture note no longer calls the file surfaces
read-only, since File Viewer edit mode writes.

**One wrapper per target.** `foreignTargetKey()` is the ONE key, read by the adopt route and `adoptedBy`, built from the location, the host identity, the socket and the name: a socket and a name alone collide across containers and hosts. Both read live `Session`s, since the mux record only exists after the first attach.
**No workspace.** ⚠️ An adopted session keeps its connection on `adopt.remote`/`adopt.docker`, so `session.remote` and `session.docker` are undefined, and its `workingDir` is the neutral `/tmp`. Code that branches on those two reads an in-container or over-ssh adoption as a local session working in `/tmp`. So anything that treats `workingDir` as the session's workspace must also test `session.isAdopted` (`adopt` on a pure view): uploads, the upload GC, git status, git fetch and its scheduler, the image watcher, Read My Mind's git signals, the Discord folder, `last-response` and guarded input all do. The Files panel still lists `/tmp`: read-only, and adoption is admin-only in multi-user mode. A wrapper reports `statusLineExporter: 'remote'`, which is also what keeps keep-warm off it.

**Lifecycle.** `paneExitApplies` is false for a wrapper, so an attach that ended is never `paneExit` and the sweep never closes the tab. Boot recovery re-attaches a dead wrapper, which prints that the session is gone and exits. Reboot restore refuses one, since all Codeman ever had was an attach command.
