Release v4.6.57

* feat: implement durable inbound message processing for bots

- Add InboundJournal class with SQLite-backed message persistence
- Implement deduplication by (platform, account, channel_id, message_id) key
- Add claim/release mechanism for crash recovery with timeouts
- Integrate journal into BotSessionManager with async context managers
- Update all bot adapters (Telegram, Discord, Slack, WhatsApp, Email, AgentMail) to pass message_id and account
- Provide exactly-once processing for webhook redeliveries and crash scenarios
- Backward compatible - existing code works unchanged

Fixes #1915

🤖 Generated with [Claude Code](https://claude.ai/code)

Co-authored-by: MervinPraison <[email protected]>

* fix: critical bugs in durable inbound message processing

- Fix claim/release mechanism: context managers now properly release claims on exceptions
- Fix overflow cap enforcement: evict oldest pending entries when no completed entries available
- Fix early complete() timing: add delayed completion method for post-delivery completion
- Fix documentation example: correct parameter name from 'journal' to 'ingress_journal'

Fixes identified by Greptile code review.

+"""
+Inbound Message Journal for PraisonAI bot adapters.
+
+Provides durable inbound message processing with deduplication, persistent
+ingress journal, and idempotent replay to prevent duplicate agent runs and
+silent message loss during crashes or webhook redeliveries.
+
+Design constraints (per PraisonAI principles):
+  - Wrapper-only — heavy implementation stays out of core SDK
+  - Lazy: sqlite3 is stdlib so no extra dependency  
+  - Optional: BotSessionManager works exactly as before unless journal is provided
+  - Bounded: TTL + max_size prevent unbounded disk growth
+  - Thread-safe: per-instance threading.Lock guards SQLite writes
+  - Atomic: claim/complete mechanism ensures at-least-once with effective exactly-once
+
+Storage schema::
+
+    ingress_journal(
+        id INTEGER PRIMARY KEY AUTOINCREMENT,
+        ts REAL,
