fix(mobile): stabilize glass, composer layout, and streaming markdown

[rynfar]

Mobile glass surfaces exposed sharp background text, composer bounds could stop between frames, and streaming code repeatedly lost highlighting. This adopts the completed upstream mobile reliability chain: backed blur, synchronized composer geometry and focus restoration, tablet close controls, stable Markdown identity, incremental code highlighting, and Android icon wrapping/copy sanitation.

Pylon’s composer shadow, provider admission, Prime session widgets, follow-up queues, rollback controls, and voice interactions remain intact. The iOS composer still uses 220 ms vertical transitions with system reduced-motion behavior; Android keeps its non-animated row/composer layout path. Reanimated is built from source so its native final-frame patch is included. Native changes require a subsequent compatible mobile binary; this PR publishes or installs none.

Part of #497. Frozen upstream range: 6c583620ff7ad3235b135af7107c0543467eecfa..4a4c6dd2adc350a68ba18bb28b24b5a7e4660dab.

The #11079/#11098 fix/revert pair cancels exactly over all nine paths. Only the final native span factory (#11118) and Android non-breaking icon spacer with clipboard sanitation (#11234) are retained. The Hermes userInput.ts sort hunk is tracked with #11014 in the parallel chat lane; that file does not exist on this PR’s base, so this PR does not claim full adoption of #11233 on its own.

Verification:

• 227 focused tests across 11 files pass, including incremental grammar state, stable keys, completed-line fallback, Hermes without ES2023 array methods, layout/navigation, glass/theme and voice presentation. The first run read a stale local file dependency during reinstall; the refreshed Markdown suite passes all 38 tests.
• Mobile and client-runtime typechecks pass. Changed-file lint passes with existing React/compiler warnings. Changed-file formatting and whitespace checks pass.
• Frozen install succeeds with the Reanimated patch. Native static discovery runs, but SwiftLint/ktlint/detekt are unavailable locally. Android Robolectric tests were imported; Java/Android SDK are absent here, so those tests and native runtime behavior were not run locally.
• No Pylon screenshots or video were captured in this lane; computer-use authorization is absent. Upstream before/after evidence is linked below as source evidence, not a Pylon runtime claim.

Upstream visual evidence: glass and controls, backed Android blur, final native animation frame, composer/sidebar and focus handoff, streaming code, Android icon wrapping.

Independent adversarial review completed against 65a3a070076251958087ac1833223f5b1fad8255: no actionable findings. Reviewed glass fallbacks and preserved Pylon composer/Prime props, width/height and focus restoration, stable Markdown identities and incremental highlighting, Android span/copy handling, and the Reanimated final-frame patch. 227 focused tests plus mobile/client-runtime types and scoped checks passed; final-head CI including native static checks is green. Native platform runtime and visual validation were not performed. The one shared Hermes userInput sort hunk is tracked in #507; its target file does not exist before that PR. Landing under standing maintainer approval.
