merge: sync with upstream pingdotgg/t3code

[SparshKaushik]

Syncs the fork with upstream main through ab099178a (78 commits): upstream's usage reader rewrite (Cursor keychain-gated account usage, Antigravity reader, OpenCode legacy JSON + multi-db), session-title generation for OpenCode, Connect relay/session-reaper idle wakeup cuts, device-tool prompt fix (pingdotgg#13908), and assorted web/mobile fixes.

Fork deltas preserved on top:

• pi usage ingestion, per-instance OpenCode DB resolution, models.dev catalog + UsagePricer/userTagged/searchModels
• UsageRecord carries both sides' fields (apiProvider, inputTokensEstimated, rateModel, fast); contract version 9 with decoding defaults so v4–v8 upstream summaries still merge
• Upstream sqlite readers rerouted through sqliteCompat (Bun-safe for the compiled binary)
• opencodeRuntime.ts stays deleted (out-of-process OpenCodeHost)
• release.yml keeps the fork's asset set (mac arm64 + s5code-server linux binaries + optional APK)
