fix(ui): correct mirrored chat empty-state + clipped IP placeholder; add readiness-check skill; privacy page nav/meta

- app/session/[id].tsx: chat empty-state rendered mirrored on Android (inverted FlatList) — now an untransformed overlay
- app/connection/add.tsx: shortened clipped host placeholder
- .agents/skills/readiness-check: production-readiness gate (Play+F-Droid published, app+site health)
- docs/privacy: back-nav + canonical/theme-color/description meta
Verified: tsc clean, CUA smoke green (run 26814702062)
