lowercase serde rename for enums and bump version to 0.13.1

Core Changes:- Bump workspace version from 0.13.1 to 0.13.2- Add handshake timeout checks for both MQTT v3 and v5 protocols- Track handshake start time and enforce listener.handshake_timeout- Return ServiceUnavailable/ServerUnavailable when timeout exceededDependency Updates:- Update rmqtt-raft dependency from 0.4.5 to 0.5.3- Maintain reuse feature flag for raft implementationProtocol Improvements:- v3: Added timeout check before client ID validation- v5: Added timeout check before client ID validation- Both protocols now properly handle handshake timeouts

feat(handshake): add timeout checks and update dependencies

cargo clippy --fix and fmt

- Set `panic = "abort"` in release profile configuration- Improves release binary size by removing panic unwinding infrastructure- Maintains existing optimization settings (lto=true, opt-level='s')

build: enable panic abort in release profile

Version & Core:- Bumped workspace version from 0.13.2 to 0.13.3- Standardized string conversion patterns across bridge componentsString Handling Improvements:- Replaced `.as_ref()` with explicit `.to_string()` for:  * MQTT client IDs in both ingress/egress bridges  * User properties in publish messages  * Content type and response topic fields- Ensured consistent string conversion in v3/v5 protocol handlersBridge Components:- Updated both ingress and egress MQTT bridges- Applied changes to both v4 and v5 protocol implementations- Maintained all existing timeout and keepalive functionality

feat(bridge): improve string handling and bump version to 0.13.3

Version & Core:- Bumped workspace version from 0.13.3 to 0.13.4Performance Improvements:- Changed offline_messages from Vec to VecDeque for efficient FIFO operations- Replaced pop() with pop_front() for proper queue behavior- Used push_back() instead of push() for correct queue orderingKey Benefits:1. **Efficiency**: VecDeque provides O(1) amortized time for both ends2. **Correctness**: Ensures proper first-in-first-out delivery of offline messages3. **Memory**: Better memory utilization for queue operations4. **Behavior**: Maintains message ordering during offline storage and retrievalThe changes ensure that offline messages are processed in the correct order while improving performance for queue operations.

…row checkingAPI Consistency:- Added explicit lifetime annotations to HTTP API Message::decode()- Added missing allow(dead_code) for AtomicFlags methodsType Safety:- Added lifetime parameter to last_will() return type in ConnectInfo- Added explicit lifetimes to plugin manager methods:  * get() -> EntryRef<'_>  * get_mut() -> EntryRefMut<'_>  * iter() -> EntryIter<'_>Key Benefits:1. **Clarity**: Makes lifetime relationships explicit in function signatures2. **Safety**: Helps Rust compiler verify proper borrow checking rules3. **Consistency**: Uniform lifetime annotation patterns across codebase4. **Maintenance**: Reduces potential lifetime-related bugsThe changes improve code robustness by making lifetime dependencies explicit without altering runtime behavior.

Code Simplification:- Removed unnecessary curly braces around `matches()` calls in all bridge implementations:  * Kafka egress bridge  * MQTT egress bridge  * NATS egress bridge  * Pulsar egress bridge  * ReductStore egress bridgePattern Matching Improvements:- Removed redundant `ref` patterns in Pulsar ingress bridge:  * Simplified `RemoteProperties(name, ref placeholder)` → `RemoteProperties(name, placeholder)`  * Simplified `RemotePayload(path, ref placeholder)` → `RemotePayload(path, placeholder)`  * Removed unnecessary `ref` keyword for string parametersKey Benefits:1. **Readability**: Cleaner, more idiomatic Rust code2. **Performance**: Eliminates unnecessary scoping blocks3. **Consistency**: Uniform pattern matching style across bridges4. **Maintenance**: Reduced cognitive load for future changesThe changes maintain identical functionality while improving code clarity and consistency across all bridge components.
