Replace scattered reason string literals with a centralized type hierarchy:
- AgentTriggerReason: all possible trigger reasons
- ClaudeRotationReason, CodexRotationReason, NoFallbackCooldownReason:
derived subtypes for specific contexts
- AgentErrorClassification, FallbackTriggerResult, CodexRotationTriggerResult:
discriminated unions for compile-time narrowing
Remove dead export isUsageExhausted() (superseded by
isPrimaryNoFallbackCooldownActive). Replace NO_FALLBACK_COOLDOWN_REASONS
Set with isNoFallbackCooldownReason() type guard.
Add tests for agent-error-detection and provider-retry (423 total passing).
Known limitation: 6 `as CodexRotationReason` casts in Codex rotation paths
where streamed trigger reason is AgentTriggerReason but runtime value is
always CodexRotationReason-compatible.

- Remove OPENAI_API_KEY from .env and Codex child process env to prevent
API billing when subscription quota is exhausted
- Remove writeCodexApiKeyAuth entirely — Codex now uses OAuth only
- Add 9-pattern secret redaction in formatOutbound() to prevent key leaks
- Fix Codex usage bucket aggregation: use 'codex' bucket only instead of
max across all buckets (bengalfox = Codex Spark, not needed)
- Add d7≥100% auto-rotation in updateCodexAccountUsage to skip exhausted
accounts and prevent API billing fallback
- Add findNextCodexAvailable that checks both rate-limits and d7 usage
- Clean stale apikey auth.json files from all session directories
- Update tests: OAuth-only auth, d7 auto-skip (3 new tests), dashboard

- Iterate all rate limits per account instead of just display[0]
- Track and persist 7-day reset time separately (resetD7At)
- Show both 5h and 7d cached usage for inactive Codex accounts
- Scan all Codex accounts by spawning app-server with each auth dir
- Cache primary (5h) and secondary (7d) usage per account
- Show cached usage + reset remaining time on dashboard
- Persist d7 usage in rotation state file
- formatResetRemaining: "Xh Ym 후" / "N일 후" format
- Remove isRateLimited guard for cached display
- Parse "try again at" time from rate-limit errors instead of
fixed 1-hour cooldown, with 3-min buffer after reset
- Pass error message to rotateToken/rotateCodexToken for parsing
- Cache usage % and reset time per Codex account for dashboard
- Persist cached usage in rotation state file across restarts
- Show rate-limited Codex accounts with cached 100% + reset time
- Fix dashboard text indicators (*!/space) for monospace alignment
- Save currentIndex + rateLimits to JSON file in DATA_DIR
- Restore on startup so rotation survives service restarts
- Replace emoji indicators with text (*/!) for monospace alignment
- Dynamic column width based on longest name
- Show Codex accounts with plan type on dashboard
- New codex-token-rotation module: rotates between multiple
~/.codex-accounts/{n}/auth.json on rate-limit
- Copies active account auth to session dir before each spawn
- Fix detectFallbackTrigger to match "usage limit" / "hit your limit"
- Fix streamed error detection: remove claude-only guard so codex
rate-limit errors are caught even when output.status is "success"
- Add rotation in both task-scheduler and message-agent-executor
