test(tui): extend coverage gate to Ink components + App.tsx (closes #1501) (#1538)
* test(tui): cover useSelectableList hook + leaf Ink components (#1501)

Add ink-testing-library and renderer-based tests for useSelectableList,
SelectableItem, and Tabs. Widen the vitest include glob to .test.tsx and
lift these files from the interim React-surface coverage exclusion. The
blanket src/components/**/*.tsx exclude is expanded into an explicit
per-file list so remaining components can be lifted incrementally.

* test(tui): cover all Ink tab + modal components via renderer tests (#1501)

Add ink-testing-library tests for the 12 Ink components (InfoTab, AuthTab,
ResourcesTab, PromptsTab, ToolsTab, NotificationsTab, HistoryTab,
RequestsTab, and the Tool/Resource/Prompt test modals + DetailsModal),
mounting them through the ink-scroll-view / ink-form passthrough doubles
and driving keypresses via stdin. Modal components render position:absolute
(empty frame under the test renderer) so their tests assert on behavior —
injected InspectorClient fakes and onClose — while the passthrough
ScrollView still mounts the inner JSX for coverage.

Lift these 12 components from the interim React-surface exclusion in
vitest.config.ts; only App.tsx remains excluded. All files clear the
uniform 90/90/90/90 per-file gate.

* test(tui): add App.tsx renderer-test harness + foundation tests (#1501)

Mock the full @inspector/core surface (InspectorClient, the 7 managed-state
classes, the 8 react hooks, transport + auth) behind a controllable harness,
plus the ink-scroll-view/ink-form passthroughs, so App renders under
ink-testing-library and its keyboard state machine can be driven via stdin.
Concurrent ink mounts share raw-mode stdin, so each render is unmounted in
afterEach. Foundation covers server-list nav, tab accelerators, connect/
disconnect, OAuth-tab gating, and connected-status rendering (~50% baseline).

* test(tui): cover App.tsx via mocked-core renderer tests; lift final exclusion (#1501)

Extend App.test.tsx to 67 tests driving the keyboard state machine, tab
content, modals, OAuth flows, and connect/disconnect across the controllable
@inspector/core mock. App.tsx now clears the 90/90/90/90 per-file gate
(94.6/90.6/94.5/96.6).

Remove the last React-surface exclusion (src/App.tsx) from
clients/tui/vitest.config.ts. The whole clients/tui/src tree is now under
the uniform per-file coverage gate with no React-surface exclusions,
completing the interim-scope lift from #1484.

* test(tui): raise stdout max-listeners in App test to silence warning (#1501)

* test(tui): raise App.tsx branch coverage >90 and de-flake coverage runs (#1501)

Add targeted App.tsx tests for the OAuth handlers' non-Error throw arms
(quick onCallback, guided start/advance, run-to-completion) and a re-entrant
quick-auth guard, lifting App.tsx branch coverage 90.6% -> 91.48% for a
safer margin above the 90 gate.

Harden the App renderer tests against the heavier v8 coverage instrumentation,
where React+ink's multi-macrotask render scheduling races fixed ticks:
- press() now settles two ticks per key so focus/tab changes flush before the
  next key is routed (ink re-subscribes useInput on re-render);
- expectFrame()/waitUntil() poll for frame content and async flow state
  (callbackServer opts) instead of asserting after a single fixed tick;
- ResourcesTab's content-clear test polls for fetched content likewise.

Plain 'npm test' (the CI path) was already stable; this makes the local
coverage gate stable too (13/13 clean runs vs ~2/8 flaky before).

* test(tui): de-flake component renderer tests under slow CI (#1501)

CI flaked on AuthTab's 'renders quick auth results' under the plain test run:
its oauthFlowState is populated by a post-mount useEffect reading the
inspectorClient, and a single-macrotask tick can race that effect -> setState
-> re-render chain on a slow/loaded CI runner.

Make each component test file's tick() flush several macrotask cycles so such
chains settle deterministically before assertions (no test relies on precise
tick timing — no fake timers / debounce). App.test.tsx already polls via
expectFrame/waitUntil and passed CI, so it's unchanged.

* test(tui): address review — shared setupFile for max-listeners, consume-once ink-form global (#1501)

Review follow-ups on #1538 (both non-blocking cleanups):

- Hoist process.std{out,in}.setMaxListeners into a shared vitest setupFile
  (__tests__/setup.ts) wired via setupFiles, so every renderer test file
  inherits it and the MaxListenersExceededWarning is silenced across the
  whole suite — not just App.test.tsx. Remove the per-file call.
- Make the ink-form double consume (clear) __INK_FORM_SUBMIT_VALUE__ on
  submit, eliminating the latent cross-test coupling on the shared global
  regardless of how the modal test files are organized.

No production code changed; suite + coverage gate stay green (App.tsx
94.8/91.5/94.5/96.6), and the warning no longer prints.

// Shared vitest setup for the TUI renderer tests.
//
// Each ink-testing-library mount of a component that listens for terminal
// resizes (App.tsx and the test modals) registers a `process.stdout` "resize"
// listener for its lifetime. Across a file's many mount/unmount cycles the
// transient count briefly exceeds Node's default warning threshold of 10,
// printing a misleading "MaxListenersExceededWarning" (the listeners are
// removed on unmount — there is no real leak). Raising the cap here, in a
// setupFile that every test file inherits, silences the noise everywhere
// rather than per-file.
