Performance Validation and Benchmarking

[lxsaah]

Comprehensive benchmarks validating error handling performance meets design constraints.

Acceptance Criteria

• Error construction benchmarks (<1μs embedded, <10μs std)
• Memory usage validation (≤64 bytes embedded)
• Async error handling performance impact measurement
• CI integration for performance regression detection

Performance Targets

Platform	Construction	Memory	Propagation
MCU	<1μs	≤64B	<100ns
Edge	<10μs	≤256B	<1μs
Cloud	<50μs	Reasonable	<5μs
