- Cargo.toml: add documentation and readme fields; expand the exclude
list so deny.toml, justfile, mise.toml, .github, .jj, fuzz, and any
cargo-mutants output never ship in the published tarball.
- README: badges, install snippet for both feature shapes, testing
matrix.
- CHANGELOG.md: keep-a-changelog skeleton with a 0.1.0 entry.
- Revert framing.rs let-chain back to nested if-let so the published
MSRV holds at the edition-2024 floor (1.85). Behaviour unchanged.
cargo publish --dry-run packages cleanly.
