The gate took its root from `git rev-parse --show-toplevel || pwd`, so
running it by absolute path from another directory found no skills and
exited 2. Derive the root from the script's own location; the optional
argument still overrides it.
The real-corpus test accepted exit 0 or 1, so it only caught a crash.
It now asserts exit 0. New cases cover a foreign cwd, a skill without
references/sources.md being skipped, several failing skills all being
reported, and an errored skill alongside a failing one.

Nothing ran validate-provenance.sh across the real corpus, so the 36
INFOs it reported for Research doc mismatches were found only by a
manual loop, and a FAIL tier would have been inert. Add
scripts/check-provenance-corpus.sh, which runs the validator over every
plugins/*/.apm/skills/*/ that has references/sources.md.
Exit 1 when any skill FAILs, naming them; INFO lines are printed but do
not fail; exit 2 when the gate cannot run (missing validator, validator
exit 2, or no skills found). Registered as a pre-push hook shaped like
check-scope-walkup-sync, documented in docs/spec/gates.md, and pinned in
test-adr0020-contract.sh's list of repo-authored hooks.
