* feat(gateway): per-platform admin/user split for slash commands
Adds an opt-in two-list access control on top of the existing per-platform
`allow_from` allowlists, scoped to slash commands only:
- allow_admin_from — full slash command access
- user_allowed_commands — what non-admins may run
- group_allow_admin_from — same, group/channel scope
- group_user_allowed_commands
When `allow_admin_from` is unset for a scope, gating is disabled and every
allowed user keeps full access (backward compat). Plain chat is unaffected.
`/help` and `/whoami` are always reachable so users can see what they
can run.
Gate runs at the slash command dispatch site in gateway/run.py and uses
`is_gateway_known_command()`, so it covers built-in AND plugin-registered
commands through the live registry without per-feature wiring.
Adds `/whoami` showing platform, scope, tier, and runnable commands.
Salvage of PR #4443's permission tier work, scoped down. The full tier
system, tool filtering, audit log, usage tracking, rate limiting,
`/promote` flow, and persistent SQLite stores are not included here —
those can be re-expanded later if needed.

* fix(gateway): close running-agent fast-path bypass + add coverage and central docs
The slash command access gate was only applied at the cold dispatch site
(line ~5921). When an agent was already running, the running-agent
fast-path block (line ~5574) dispatched /restart, /stop, /new, /steer,
/model, /approve, /deny, /agents, /background, /kanban, /goal, /yolo,
/verbose, /footer, /help, /commands, /profile, /update directly
without going through the gate — letting non-admins bypass gating just
because an agent happens to be busy.
Refactored the gate into _check_slash_access() and called from BOTH
paths. /status remains intentionally pre-gate so users can always see
session state.
Also added 18 more dispatch tests covering:
- Running-agent fast-path: blocks non-admin, allows admin, /status
always works
- Alias canonicalization (gate uses canonical name, not user alias)
- Unknown / unregistered commands pass through (don't false-positive)
- DM admin scope-locked when group has its own admin list
- Multi-platform isolation (Discord gated, Telegram unrestricted)
Docs: added Slash Command Access Control section to the central
messaging index page + /whoami row in the chat commands table.
