v0.4.0

Added

• Public Observe enum with subscribe/unsubscribe values (#7).

Performance

• Frontend-inline option length decoding to avoid error-result stack temporaries, without changing validation, allocation policy, ownership or the public decoder API (#8).
• Exhaustive regression coverage for option values, truncation/overflow errors and cursor movement (#8).

Toolchain

• Minimum Zig version remains 0.15.1.
• On Apple Silicon, stock Zig 0.15 cannot read the arm64e-only system-library stubs in macOS SDK 26.4+. CI selects Xcode 26.2/SDK 26.2; see the README for the compatibility note (#9).
• Linux and macOS tests and optimized benchmarks pass on the release commit.
