Phase 1 app: session list, session screen, spawn, QR enrollment over pinned TLS

Compose app mirroring local-updater's stack (single :androidApp module,
pinned CA, HttpURLConnection transport) plus what this app needs on top:
a bearer token sealed with an Android Keystore AES-GCM key, an
aiapp://enroll intent filter so scanning the server's terminal QR with
the stock camera enrolls the phone with no QR library, an SSE client
that resumes by transcript cursor, and a transcript renderer folding the
common event model into user bubbles, streaming text, collapsible tool
cards, and answerable question cards.

Verified on the tdep emulator against the real server: enrollment deep
link, list, spawn, streamed echo turn, question answer round trip, tool
card expansion, adjustResize keyboard behavior. Build is warning-clean
(compose.* accessors replaced with direct dependencies).
