docs(changelog): backfill 0.2.0 entries missed in the merge churn

Audit of merged PRs since v0.1.2 surfaced user-facing changes absent from
both changelogs: Flutter warmup/unload + async symmetry (#293), boltffi
0.25.3 error-drop/buffer-leak fix (#276), strip-safe 16KB Android .so
(#287), Kotlin exhaustive displayMessage (#273), iOS-sim bindgen triple
(#274), RN Expo example (#294), and the prebuilt-natives CI pipeline
(#281-#291). Build-only CI plumbing left out of the consumer changelog.

 * Raw-frame path avoids per-frame JPEG re-encoding: `imageRaw` packs RGB pixel buffers straight through to the multimodal runtime; the encoded `image` path remains the fallback (xybrid-ai/xybrid#245)
 * Streaming TTS support on top of the new audio generation path (xybrid-ai/xybrid#245)
 * Live-mode telemetry is rate-limited by a per-session sampler (≈1 row/sec/session), so live camera sessions no longer emit a telemetry row per frame (xybrid-ai/xybrid#245)
