docs: update AGENTS.md with accurate bot architecture and config

[simonkberg]

Summary

• Fix misleading simon-bot description — it runs via instrumentation.ts WebSocket subscription at server boot, not via after()
• Add undocumented next.config.ts settings (output, cacheComponents, reactCompiler, globalNotFound)
• Add config.ts and instrumentation.ts to directory structure
• Document rate limit gate and Redis-based message deduplication in Discord/bot sections

Test plan

• Verify AGENTS.md renders correctly on GitHub
• Confirm all documented config flags match next.config.ts

Code Review

• Gather context and read changed files
• Verify documented settings match actual source files
• Review documentation accuracy and completeness
• Post final review

---

All documented changes verified against source. The PR is accurate and clean — here are my findings:

Verified correct:

• Bot startup via instrumentation.ts → startBotSubscription() is confirmed (instrumentation.ts:3-6, bot.ts:83-87)
• All five next.config.ts settings (output, cacheComponents, reactCompiler, typedRoutes, experimental.globalNotFound) match the actual config (next.config.ts:6-12)
• Rate limit gate documented correctly — backed by the rateLimitUntil map in api.ts:28
• Redis deduplication: SEEN_TTL = 60 and markSeen() in bot.ts:25-33 confirm the 60s TTL claim
• Claude Haiku 4.5 and 5-second timeout both confirmed in anthropic.ts:20,229
• Regex pattern /\bsimon[- ]?bot\b/i matches BOT_MENTION_PATTERN in bot.ts:15
• config.ts and instrumentation.ts both exist at their documented paths

Minor omissions (not blocking, intentional omissions are fine):

Two next.config.ts settings are undocumented in the "Key settings" list:

• logging: { fetches: { fullUrl: true } } — dev-only debug logging, omitting is reasonable
• turbopack: { root: import.meta.dirname } — since pnpm dev uses Turbopack and this sets the root resolution path, it could be worth a bullet point to help agents understand why the Turbopack config is there. Not critical though.

Overall: Documentation is accurate and a clear improvement over what it replaced. The bot architecture fix in particular removes genuinely misleading information. Ready to merge.
