[0xVida]

Description:
Prevent race conditions in multi-node settings by wrapping the GCRA rate-limiting check in transactional Lua blocks.

Requirements and Context:

CRITICAL CONTEXT: All code changes and execution steps for this issue must happen strictly within the server folder of the repository. Ensure you are working inside the server/ directory before beginning.

The Fluid platform requires professional-grade resilience & error handling standards. This issue focuses on redis transactional lua script locks for gcra to ensure the system is production-ready and resilient.

Acceptance Criteria:

• Ensure full test coverage (unit and integration)
• Verify compliance with internal design and security standards
• Validate Redis Transactional Lua script Locks for GCRA handles edge cases correctly

Deliverables:

• Code implementation in server/src
• Updated documentation in /docs
• Verification report with terminal output/screenshots

NOTE: This issue will NOT be reviewed or approved without functional screenshots or verified terminal output where applicable!

Suggested Execution:

1. Research existing implementation in server
2. Draft a technical design for Redis Transactional Lua script Locks for GCRA
3. Execute implementation and verify against local environment
4. Run full test suite to ensure no regressions

Guidelines:
