* feat(tui): single /model command + unified Sessions overlay
Collapse the redundant `/provider` alias so `/model` is the only name
everywhere (it already drove the same 2-step ModelPicker in the TUI).
Merge the separate `/resume` (cold history browser) and `/sessions` (live
switcher) surfaces into one Sessions overlay reached by `/resume`,
`/sessions`, `/session`, and `/switch`. It pins a "+ new" row at the top
(always visible), lists live sessions with status, and lists resumable
history below — dispatching session.activate for live rows vs resume for
cold ones, with close/delete in place. Fixes `/session` opening an empty
live-only switcher and the hidden new-session affordance.

* fix(tui): address Copilot review on the Sessions overlay
- Track the armed history-delete by session id instead of row index so the
1.5s live-status poll re-indexing rows can't redirect the second `d` to a
different session.
- Re-add the busy-session guard to immediate `/resume <id>` and `/sessions new`
actions (browsing the bare overlay stays allowed) so resuming/switching can't
corrupt an in-flight turn's streaming/busy state.
* fix(tui): guard cold-resume (not live-switch/new) from the Sessions overlay
Copilot flagged that overlay actions bypassed the busy guard. Only cold
resume actually closes the current session, so only it is guarded — both
from the slash path and now from the overlay (appActions.resumeById).
Switching between live sessions and starting a `+ new` live session keep
the current session running in the background, so they stay unguarded:
that concurrency is the orchestrator's whole purpose. Also dropped the
over-broad guard on `/sessions new` for the same reason.
* fix(tui): address Copilot review (history dedup + desktop /provider)
- The 1.5s poll now re-derives the resumable list from the RAW session.list
results (rawHistoryRef) against the current live set, so a session hidden
while live reappears in history once it closes — instead of being lost
until a full reload. Delete also prunes the raw ref.
- Drop the dead `/provider` entry from the desktop PICKER_OWNED_COMMANDS now
that the alias is gone, so the desktop client no longer advertises it.
* fix(tui): surface session.list errors + keep selection stable across polls
- A garbled session.list response now surfaces an error and preserves the
last good raw history, instead of silently blanking the resumable section.
- The 1.5s poll re-anchors the selection to the same row by session id
(live or history) when the live list grows/shrinks, so the highlight no
longer drifts to a different row mid-interaction.
* fix(tui): degrade session.list independently + cover overlay helpers
- Fetch active_list and session.list via Promise.allSettled so a failing
session.list no longer rejects the whole load: live sessions still render
and only the resumable history degrades (with an error).
- Add unit tests for the new helpers (sessionRowKindAt row ordering,
resumableHistory dedupe, sessionsCountLabel, relativeSessionAge).
* test(tui-gateway): assert /provider alias is gone, /model remains
The CI test_complete_slash_includes_provider_alias asserted the removed
`/provider` alias still autocompleted. Flip it to lock in the removal:
`/pro` no longer offers `provider`, and `/mod` still completes `model`.
