API Consistency:
- Added explicit lifetime annotations to HTTP API Message::decode()
- Added missing allow(dead_code) for AtomicFlags methods

Type 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 signatures
2. **Safety**: Helps Rust compiler verify proper borrow checking rules
3. **Consistency**: Uniform lifetime annotation patterns across codebase
4. **Maintenance**: Reduces potential lifetime-related bugs

The 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 bridge

Pattern 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 parameters

Key Benefits:
1. **Readability**: Cleaner, more idiomatic Rust code
2. **Performance**: Eliminates unnecessary scoping blocks
3. **Consistency**: Uniform pattern matching style across bridges
4. **Maintenance**: Reduced cognitive load for future changes

The changes maintain identical functionality while improving code clarity and consistency across all bridge components.
