fix(tui): resolve /compact alias collision between compress alias and TUI display toggle (#57070)

[AlexFucuson9]

Problem

PR #57029 added "compact" as an alias for the compress command (CommandDef("compress", ..., aliases=("compact",))). This collided with the pre-existing /compact TUI display toggle in _TUI_EXTRA, causing commands.catalog RPC to return /compact twice with two different meanings:

• As an alias for /compress ("Compress conversation context")
• As a standalone TUI command ("Toggle compact display mode")

Impact: Clients that treat pairs entries and canon aliases as mutually exclusive crash on startup (e.g. fathah/hermes-desktop#802).

Changes

1. Rename /compact TUI display toggle to /compact-ui in _TUI_EXTRA
2. Dedup guard in commands.catalog handler: skip _TUI_EXTRA entries whose name already appears as a registered command or alias in canon
3. Backward compat: settings.toggle and settings.get handlers accept both "compact" and "compact-ui" keys
4. Autocomplete: update extras to use /compact-ui

Fixes #57070

Competing fix cluster for #57070 (all open, all fixing the /compact catalog collision introduced by merged #57029 via different edits): this PR (#57131) renames the legacy TUI toggle to /compact-ui and adds a commands.catalog dedup guard; #57073 keeps /compact in canon and omits the toggle from the catalog; #57078 lets command aliases override TUI extras. Related to #57029 (the merged alias that introduced the regression). Flagging for a maintainer to pick the canonical approach; not marking any as duplicate.

Thanks for tracing the catalog collision; it is still present on current main.

Problems

• tui_gateway/server.py changes the catalog-only name to /compact-ui, but the local TUI registry still implements only compact at ui-tui/src/app/slash/commands/core.ts:279-290. The new catalog command therefore has no local TUI handler.
• Please add coverage for the collision contract. Current catalog tests at tests/test_tui_gateway_server.py:4511-4582 cover quick commands, /mouse, and hidden gateway commands, but not /compact alias/catalog behavior.

Suggested changes

• Rename or alias the local TUI toggle to compact-ui, retaining the proposed config-key compatibility bridge.
• Assert that catalog pairs excludes /compact, includes /compact-ui once, and that canon['/compact'] resolves to /compress.

/compact-ui is only introduced in this backend catalog. The local TUI registry still recognizes compact at ui-tui/src/app/slash/commands/core.ts:279-290, so this advertised command has no local toggle handler. Rename or alias that frontend command and add an execution regression test.

The /compact collision is fixed via #69303 (merged) — salvage of #57162 (broadest of the three competing fixes, covering ACP + TUI + catalog dedup). Your fix is credited in the merged PR body as an independent solution. Thanks!
