feat(stabilization)!: thread_aware 1.0

[martintmk]

Summary

• Adds thread_aware_core 1.0.0 with the stable ThreadAware trait and Affinity type.
• Keeps the core crate dependency-free and always no_std; an opt-in std feature adds standard-library implementations for HashMap, Path, and PathBuf.
• Re-exports the stable APIs from thread_aware, preserving thread_aware::ThreadAware and thread_aware::affinity::Affinity; dependent crates reference the stable core types directly in public APIs.
• Removes external-crate integration features and documents the stable boundary and affinity invariants.

Validation

• thread_aware_core and thread_aware tests and doctests pass with all applicable features.
• Both crates compile without default features.
• thread_aware_core packages and verifies successfully with zero dependencies.
• Formatting, generated README, spelling, Clippy, mutation, coverage, and external-type checks pass.
• Independent Claude and Gemini reviews completed; their documentation findings were addressed.
