🐛 Bugs Fixed

1. 🔁 Bad MAC Retry Loops

Symptom: Messages fail to decrypt, bot gets stuck in an infinite retry loop.

Fix: Replaced plain Map with a full MessageRetryManager class that:

• Detects MAC errors via RetryReason enum and forces immediate session recreation
• Tracks retry counts per message with LRU expiry (15-min TTL)
• Prevents session recreation hammering with a 1-hour cooldown
• Supports phone-based resend fallback with cancellable timeouts

2. 🔄 Permanent Bad MAC After Contact Re-registers

Symptom: After a contact reinstalls WhatsApp, every message from them fails to decrypt permanently.

Fix: Added handleIdentityChange() which:

• Listens for identity change push notifications
• Debounces rapid identity changes per JID
• Forces Signal session teardown and rebuild via assertSessions(force=true)

3. ⚡ Pre-key Race Conditions

Symptom: Intermittent decryption failures under high message load.

Fix: Added PreKeyManager which:

• Creates a separate PQueue (concurrency: 1) per key type
• Serialises all reads/writes, eliminating race conditions

4. 🧊 Event Loop Blocking on Reconnect

Symptom: Bot becomes unresponsive for seconds after reconnecting with a large backlog.

Fix: Added makeOfflineNodeProcessor() which:

• Yields to the event loop every 10 nodes
• Catches per-node errors without crashing the processing loop

5. 📨 Incorrect ACK Stanza Construction

Symptom: Some ACKs were missing the from field, causing server-side routing issues.

Fix: Added buildAckStanza() — always includes correct fields matching WA Web behaviour.

6. 🪪 LID-Addressed Messages Failing to Decrypt

Symptom: Messages from LID-format JIDs silently fail to decrypt.

Fix: Added LIDMappingStore with:

• Bidirectional LID ↔ Phone Number mapping
• LRU in-memory cache (3-day TTL)
• In-flight request deduplication

7. ❌ Error 463 on 1-to-1 Message Sends

Symptom: Occasional 463 error — message never delivered.

Fix: Full tctoken system — reads, stores, and attaches privacy tokens to outgoing messages.
