A bare `/resume` printed the recent-sessions list but armed no selection
state, so typing just `3` on the next line was sent to the agent as chat
instead of resuming session #3. `/resume 3` worked, but the natural
list-then-pick flow did not.
Arm a one-shot pending-resume prompt when bare `/resume` shows the list,
and consume the next bare numeric input as the selection (out-of-range is
reported, non-numeric/other commands disarm it). Resolves against the same
_list_recent_sessions(limit=10) list used everywhere else.
Closes#34584.
- CLI: bracketed/quoted target resolves; mismatched single bracket passes through unchanged.
- Gateway: bracketed session ID resolves; bare untitled session ID resolves via get_session() fallback.
The numbered /resume feature added new i18n keys to en.yaml; the catalog parity
tests require every locale to carry matching keys and placeholders, so add
translations to all 15 supported locales.
Also unblock tests/cli/test_cli_resume_command.py:
- _make_cli stub now sets self.resume_display = 'minimal' since
_handle_resume_command (post-#31695) calls _display_resumed_history.
- mock_db.resolve_resume_session_id returns the input id (no compression
chain) so HERMES_SESSION_ID is set to a real string, not a MagicMock.
