feat: add Trae CLI as a supported TUI agent (#10763)

* feat: [AI-GEN] add Trae CLI as a supported TUI agent

Closes #10579.

Wire trae-cli into the desktop and mobile agent catalogs following the
same integration pattern as other CLI agents (e.g. Ante, Devin):

- src/shared/types.ts, tui-agent-config.ts: register 'trae' with
  detectCmdAliases (traecli/trae-agent) and argv prompt injection,
  matching trae-cli's `trae-cli [prompt]` contract. The CLI's own
  third documented alias `ta` is intentionally excluded — too generic
  a 2-letter name to use as a PATH-existence detection signal without
  false-positiving on unrelated tools.
- src/shared/trae-headless-command.ts: recognize `--print`/`-p` and
  `--output-format json|stream-json` as one-shot headless invocations
  (same shape as claude-headless-command.ts) so they aren't mistaken
  for a live interactive session.
- agent-kind.ts, telemetry-events.ts, agent-status-types.ts,
  agent-type-label.ts, tui-agent-display-names.ts,
  tui-agent-permissions.ts (YOLO via trae-cli's own --yolo flag),
  tui-agent-selection.ts: standard per-agent registrations.
- agent-catalog.tsx, agent-favicon-assets.ts,
  mobile/src/tasks/mobile-tui-agents.ts,
  mobile/src/components/mobile-agent-icon-assets.ts: catalog entries
  and bundled favicon (fetched from docs.trae.cn, required by mobile's
  offline-icon invariant test).
- i18n: add the "Trae" label to all five locale catalogs (en/es/ja/ko/zh).
- Tests: agent-process-recognition, agent-status, tui-agent-startup.

Verified with `pnpm typecheck` (desktop + mobile), the relevant vitest
suites (869 tests across 12 files, all green), oxlint (clean), and a
real end-to-end launch of the actual trae-cli binary through Orca's
pty.spawn IPC path (confirmed via the OS process table).

* fix: [AI-GEN] point Trae catalog entry at the real CLI quick-start doc

docs.trae.cn/cli (what the installed CLI's own --help text prints as
its "User manual" link) soft-404s — the docs site restructured and the
working page is docs.trae.cn/cli_get-started-with-trae-cli (confirmed
by HTTP fetch: real page title "TRAE CLI 快速开始" vs the old path's
"404 - 页面不存在"). Addresses CodeRabbit's homepageUrl review comment.

* fix: [AI-GEN] detect Trae on traecli, not the ambiguous trae-cli name

Per @AmethystLiang's review: the open-source bytedance/trae-agent
project (MIT, ~12k stars) registers its own console script as
`trae-cli` (pyproject.toml: `trae-cli = "trae_agent.cli:main"`), an
entirely unrelated CLI with a different contract (`trae-cli run
"task"`, `-p` short for `--provider`). Detecting on bare `trae-cli`
would false-positive on that project's installs and break launch for
anyone who has it instead of the actual TRAE CN CLI.

- tui-agent-config.ts: detectCmd/launchCmd/expectedProcess -> `traecli`
  (TRAE CN's own installer symlinks this alias too, but the other
  project does not ship it). Dropped the `trae-agent` alias entirely —
  it's the colliding project's literal repo name, the highest
  false-positive string available.
- agent-catalog.tsx: cmd -> `traecli` to match; faviconDomain ->
  `www.trae.cn` (bare `trae.cn` 404s on Google's favicon service;
  `www.trae.cn` is the product-root domain that actually resolves).
- mobile-tui-agents.ts: faviconDomain -> `www.trae.cn` to match.
- Tests updated: agent-process-recognition now asserts `trae-cli` and
  `trae-agent` are NOT recognized as Trae (regression guard against
  reintroducing the collision); tui-agent-startup updated for the new
  launch command.

promptInjectionMode stays `argv` and the headless-command file stays
as-is — both verified against the real TRAE CN CLI's actual --help
output (pasted in the PR review thread), not assumptions.

* refactor: [AI-GEN] share one print-mode headless matcher across agents

trae-headless-command.ts was a rename-only fork of claude-headless-command.ts,
and ante-headless-command.ts carried a third copy of optionName. Collapse both
print-mode files into print-mode-headless-command.ts, dispatch from a
Partial<Record<TuiAgent, ...>> table instead of an if-chain, and compress the
Trae comments to the repo's one-line style.

* fix: [AI-GEN] terminate Trae flag parsing before the positional prompt

`traecli` is a Cobra CLI with subcommands, so an argv prompt starting with
`help`, `config`, `-…` was dispatched as a subcommand or flag instead of being
run as the task. Add `argvPromptSeparator: '--'` (same reason Grok has it), and
stop the shared print-mode headless matcher at `--` so a prompt that reads like
`--print` no longer drops the pane out of agent recognition.

* docs: [AI-GEN] name both Trae CLIs explicitly in the detect-name comment

* docs: [AI-GEN] drop the vendor tag from the Trae union comment

* fix: [AI-GEN] guard the nullable startup plan in the Trae separator test
