docs(tasks): the wave-1 review gate — the one-way-door audit green

Every gate check read against the cited ADR text: the key encoding
holds byte-exact against ADR-002 (tags, lengths, rejects, sort order,
preamble abstraction, live git-CLI interop, lowercase oid policy
recorded); the trait + I/O seams + engine-state seam match ADR-003/
010 and ADR-012 §5's reduced table; the error model's five variants
and single-enum altitude reading match store-api.md/ADR-012 §6.5; the
feature graph matches ADR-013 §4; all named design points audited
consistent; the suite convention and backlog are traceable; family
conventions clean. One inline fix: publish keyword `bao` -> `git`
(excluded technology named in metadata). Wave 2 decomposition
unblocked, no amendments.

Verified: cargo test (26 lib + 4 conformance + 3 git-interop passed),
cargo clippy --all-targets -- -D warnings, cargo clippy --all-features
--all-targets -- -D warnings, cargo fmt --check, cargo check
--all-features, cargo check --no-default-features --features pg-lo.
