Yaojia Wang 980dbaa928 feat(android): wire the dead code, render the git panel, make the token gate real
Four agents' worth of :app wiring. Everything here existed as tested code with
zero production call sites, or as a screen rendering a shape the server stopped
sending months ago.

Dead code that shipped as features. All three were fully implemented and
unit-tested while being reachable from nothing:

  - Session-list preview thumbnails. SessionsHome called SessionListScreen
    without the `thumbnails` argument, so the `= null` default won and every
    row rendered a placeholder forever — on the home session chooser, whose
    entire purpose is seeing what each session is doing.
  - Quick-reply chips and their palette editor.
  - PointerContextMenu (large-screen secondary click).

ThumbnailPipeline's formal cross-review had been explicitly skipped when it was
written — PROGRESS_ANDROID.md said so in as many words, and it is concurrency
code, so nothing had ever reviewed OR executed it. It has now been reviewed and
kept: the LruCache key, the fair Semaphore(2), the Mutex-guarded in-flight
dedup and the NonCancellable in-flight release are all sound, and a retained
map entry would have poisoned a key forever.

The v0.6 project-detail git panel. Android rendered the pre-w6 shape: one bare
dirty dot, a bare hash+subject commit row, and a worktree heading that renamed
itself to "Branch" at n=1 — the exact behaviour G5 removed. Now the sync band,
unpushed marking with a single upstream boundary, and "Worktrees (n)". The rule
that drives it is enforced, not documented: exactly one state may render green,
and no-upstream is not that state.

Remote approvals are no longer blind. status.preview reaches GateBanner and
PlanGateSheet, so the user can see the command or diff they are approving
instead of a tool name. Absent preview stays an ordinary gate, not an error.

The WEBTERM_TOKEN gate is no longer inert. NetworkModule was calling
OkHttpClientFactory.create(identityProvider) with no cookieJar, so the shared
client ran on CookieJar.NO_COOKIES and none of the cookie plumbing did
anything. It now installs the real AuthCookieJar — one client, so the cookie
rides the WS upgrade too — backed by the Tink-sealed store, and binds
InMemoryAuthCookieStore if a cipher cannot be constructed rather than ever
persisting a shell credential in the clear. The persister runs on an IO scope
because OkHttp calls a CookieJar synchronously and must never block on
DataStore or Tink.

And the user-facing half that made the gate unusable: a token-gated host
answers the pairing probe's unauthenticated GET with 401, which the frozen
taxonomy could only report as "this port is running something else" — so such
a host was impossible to pair AND the copy was misleading. Pairing now routes
to a token prompt and resumes through the same cert-gate choke point. The
token is a parameter, never a field and never part of any UI state.

Docs corrected rather than left aspirational: the plan asserted a cleartext
allowlist "permitted only for private LAN/Tailscale CIDRs", which the platform
cannot express at all — the network-security-config format has no netmask or
prefix syntax. PROGRESS_ANDROID.md now opens with what "COMPLETE" actually
meant, and PROGRESS_LOG.md records the whole pass including what is still
undone: A34/A35 have no code, and device QA remains ~0%.

Verified: ./gradlew test :app:assembleDebug :app:testDebugUnitTest koverVerify
-> BUILD SUCCESSFUL, 893 JVM tests, 0 failures (baseline was 617). The :app
run was re-measured with outputs deleted and --no-build-cache, and the APK
re-packaged, so Hilt graph validity is an observation rather than an
up-to-date claim.
