 * core-only service that writes its wrapper to a dedicated dir but leaves the
 * consumers pointing at the shared `~/.botmux/bin` would resolve `botmux` to a
 * same-HOME fleet's wrapper (shared:dedicated:… PATH → shared wins).
 *
 *  - core-only (BOTMUX_CORE_ONLY=1): a DEDICATED `<SESSION_DATA_DIR>/bin`, so a
 *    same-HOME fleet's `~/.botmux/bin` is never consulted or clobbered.
 *  - normal fleet: the shared `~/.botmux/bin` (unchanged).
 *
 * Env-driven (not config) so it resolves identically in the daemon, a forked
 * worker, and a value baked into a tmux pane script — all of which see the same
 * BOTMUX_CORE_ONLY / SESSION_DATA_DIR. Falls back to ~/.botmux/bin if a core-only
 * process somehow lacks SESSION_DATA_DIR (defensive; the entrypoint always sets it).
