v0.9.0

Added

• Tracing support: New tracing feature flag enables tracing/tracing-subscriber integration as an alternative to env_logger
• Configurable logging initialization: New log_init = function_name macro parameter allows custom log initialization functions instead of relying on defaults
• Event logging control: New event_logging = bool macro parameter controls whether Lambda event payloads are logged (defaults to false for better security)
• Structured JSON logging by default when tracing is enabled
• #[tracing::instrument] attributes on generated handler functions with request ID and operation name in trace spans
• Signature validation for the hook option with clear error messages for invalid function signatures

Changed

• Breaking: Event payload logging is now disabled by default for security reasons (can be re-enabled with event_logging = true)
• When Lambda event payloads logging is enabled, Lambda event payloads are now logged at debug level instead of info
• env_logger is now an optional feature (still enabled by default for backward compatibility)
• Independent log feature flag controls log statement generation in generated code

Fixed

• Generated main and function_handler now use fully qualified ::core::result::Result instead of Result, preventing compilation failures when users override the Result type
• Request hook trybuild test was not actually testing anything
• Release CI could fail tests but still proceed with publishing
