Summary

This PR merges autonomous maintenance and stability fixes from agent/maintenance into master:

1. JSON Round-Trip Fidelity & Escaping (Builder / Builders)

• Key Escaping: Escape object keys during serialization in appendKeyValue to pair with parser unescaping.
• Literal & Type Preservation: Parse array boolean and null literals into corresponding typed Builder values.
• Quote Retention: Keep String values quoted even when they look like numbers, booleans, or nulls so parse/toString() cycles preserve types.
• String Scanning: Fix JSON string scanning when strings end with escaped backslashes ("\\\\").
• Parity: Ensure array string elements unescape cleanly upon parsing, matching object field behavior.
• Tests: Add BuilderRoundTripTest and update BuildersTest, BuilderTest, and BuilderCharSequenceViewTest to verify round-trip fidelity.

2. Concurrency & Performance (DistributedMessageQueue)

• Fix lock starvation in DistributedMessageQueue.take() by scoping lock acquisition strictly around pollMessage(...), releasing the lock before sleeping.

3. Application Lifecycle (ApplicationManager)

• Fix uninstall(Application) to remove all actions registered by the target application rather than returning on the first match.

4. Logging Thread Safety (LogFormatter)

• Replace shared unsynchronized SimpleDateFormat with thread-safe DateTimeFormatter.

5. API Cleanup (Application / AbstractApplication)

• Remove erroneous @Deprecated annotations on setAction(String, String) to support dynamic runtime action mapping without compiler warnings.

Verification

• Builder & Builders suites: 84/84 tests passed (BuilderTest, BuildersTest, BuilderCharSequenceViewTest, BuilderRoundTripTest).
• DistributedMessageQueueTest, ApplicationManagerTest, LoggerTest passed.
• MCP Tool test suites passed.
