Merge bus fix branches across 3 repos (plugin-lib, brain, plugins)

[four-bytes-robby]

Context

Local bus fallback (MemoryBus) doesn't work cross-process in opencode's Worker-based architecture. 13 branches with bus fix improvements are unmerged across 3 repos. Merging them brings:

• MemoryBusTui upgrade (plugin-lib fix: brain_ingest tool has no TUI feedback — add toolCtx.metadata() and toast (#12) #13)
• onWarn callback (plugin-lib feat(memory): add diary write path — subMode add to brain_memory diary mode #17, brain [BUG] getBus() missing onWarn callback — bus warnings go to console.warn instead of app.log #159)
• TUI fallback guards (plugin-lib feat(memory): add diary write path — subMode add to brain_memory diary mode #22)
• Bus recovery after fallback (plugin-lib fix: vec0 extension not found at runtime + English-only system prompt #26, feat: milestone — audit fixes + memory/knowledge features from plugin analysis #28)
• Close old bus before replace (plugin-lib feat(e1): ingest pipeline upgrade — token chunks, qualified symbols, timeout, Rust, FK upsert #30)
• Dist integrity checks (brain [TEST] Pre-build dist integrity check — verify bus methods survive bundling #163)
• Binary install in build script (plugins feat(e4): architecture reliability — timeouts, progress events, startup UX #35)

Merge Plan

1. plugin-lib (8 branches — merge in this order)

fix/13-memory-bus-upgrade        → main  (foundational)
feat/17-busclient-onwarn         → main  (onWarn callback)
fix/22-tui-fallback              → main  (guard MemoryBusTui)
fix/26-tui-bus-recovery          → main  (retry real bus)
fix/28-memorybus-retry           → main  (remove blocking retry)
fix/30-close-old-bus             → main  (close before replace)
test/32-fallback-recovery        → main  (tests for all above)
fix/bustui-suppress-console-warn → main  (remove console.warn)

2. brain (4 branches)

fix/bus-onwarn-console-to-applog → main  (route bus warnings)
fix/159-bus-onwarn-status        → main  (onWarn in getBus)
fix/161-local-plugin-lib-dep     → main  (local file: dep)
test/163-dist-integrity          → main  (dist check)
