* feat(config): add experimental config schema for gating unstable features
This adds a new 'experimental' config field to the OhMyOpenCode schema that enables fine-grained control over unstable/experimental features:
- aggressive_truncation: Enables aggressive token truncation in anthropic-auto-compact hook for more aggressive token limit handling
- empty_message_recovery: Enables empty message recovery mechanism in anthropic-auto-compact hook for fixing truncation-induced empty message errors
- auto_resume: Enables automatic session resume after recovery in session-recovery hook for seamless recovery experience
The experimental config is optional and all experimental features are disabled by default, ensuring backward compatibility while allowing early adopters to opt-in to cutting-edge features.

- Add storage.ts: Functions to find and truncate largest tool results
- Add TruncateState and TRUNCATE_CONFIG for truncation tracking
- Implement truncate-first recovery: truncate largest output -> retry (10x) -> compact (2x) -> revert (3x)
- Move session error handling to immediate recovery instead of session.idle wait
- Add compactionInProgress tracking to prevent concurrent execution
This fixes GitHub issue #63: "prompt is too long" errors now trigger immediate recovery by truncating the largest tool outputs first before attempting compaction.

- Add FallbackState interface to track message removal attempts
- Implement getLastMessagePair() to identify last user+assistant message pair
- Add executeRevertFallback() to remove message pairs when compaction fails
- Configure max 3 revert attempts with min 2 messages requirement
- Trigger fallback after 5 compaction retries exceed
- Reset retry counter on successful message removal for fresh compaction attempt
- Clean fallback state on session deletion
Resolves: When massive context (context bomb) is loaded, compaction fails and session becomes completely broken. Now falls back to emergency message removal after all retry attempts fail, allowing session recovery.

Implements retry logic with up to 5 attempts when compaction fails.
Uses exponential backoff strategy (2s → 4s → 8s → 16s → 30s).
Shows toast notifications for retry status and final failure.
Prevents infinite loops by clearing state after max attempts.
