feat(happy-app): add Kimi agent support

[oymy]

Summary

• Add Kimi as a new agent option in the Happy App, alongside Claude, Codex, and Gemini
• Kimi uses the same permission mode pattern as Gemini (default, read-only, safe-yolo, yolo)
• Kimi models: kimi-k2-0711-preview (default), kimi-k1.6-preview, kimi-k1.5-preview

Changes

• sync/typesRaw.ts: Add 'kimi' to ACP provider enum
• components/modelModeOptions.ts: Add getKimiPermissionModes() and getKimiModelModes() functions; update dispatchers for permission modes, model modes, and default model key
• sync/settings.ts: Add Kimi compatibility flag and dismissedCLIWarnings support
• sync/profileUtils.ts: Add Kimi built-in profile (uses KIMI_API_KEY env var)
• components/Avatar.tsx: Add Kimi avatar icon (placeholder, copied from Gemini)
• assets/images/icon-kimi{,@2x,@3x}.png: Placeholder icon files (to be replaced with real Kimi icons)
• hooks/useCLIDetection.ts: Add kimi to CLIAvailability interface and detection logic
• sync/persistence.ts, utils/tempDataStore.ts, components/AgentInput.tsx, sync/ops.ts, app/(app)/new/index.tsx: Add 'kimi' to agent type unions throughout
• text/_default.ts + 10 translation files (en, zh-Hans, zh-Hant, ru, pt, pl, ja, it, es, ca): Add agent.kimi and kimiPermissionMode translation keys

Test plan

• Run yarn typecheck — passes with zero errors
• Verify Kimi profile appears in New Session screen agent picker
• Verify Kimi permission modes render correctly (Default, Read Only, Safe YOLO, YOLO)
• Verify Kimi models render correctly in model selector
• Verify avatar icon shows for Kimi sessions (replace placeholder icon before production)
• Verify KIMI_API_KEY env var is picked up from built-in Kimi profile

⚠️ UI tests above have not been run — manual testing on device/simulator required before merge.

Notes

• Placeholder Kimi icons are copies of Gemini icons — replace with real Kimi brand assets before release
• On the wire, Kimi uses provider: 'kimi' in ACP envelope (see happy-cli PR feat(happy-cli): add Kimi CLI support via ACP protocol #665)
