refactor(profile): strip comment noise

Removes module banners and comments restating the code. Keeps one-line
notes for the ProcessSingleton user-data-dir rule, the sentinel-URL and
async-spawn-error quirks, the replicated getAgentDir, pi's tilde-expansion
mirroring, the Windows wmic removal, the macOS/Linux process-identification
quirks, the picker's undefined-means-cancel contract, and the deliberately
unpersisted browserContextId.

- *   - the pinned profile is marked with a check
- *   - a final row clears the selection, since a pin must be undoable
- *
- * `ctx.ui.select` resolves to undefined when the user presses Escape AND in

- * dialog), so callers must treat "no answer" as "change nothing".
