484357a taught the Contributing parser the bullet form, but a block it still
could not parse returned the same empty result as an explicit "(none)", so the
checker read "no contributing files" and skipped check 8 rather than reporting
that it could not tell. Checks 7 and 8 were consequently dead across the whole
git plugin without anything failing.
The parser now distinguishes "declared none" from "could not parse", which
wakes both checks. Because the parser is duplicated between the skill-audit and
agent-audit copies, it is fenced with BEGIN/END markers and a test hashes the
two regions so the copies cannot drift apart again silently.
Addresses #111.
Description 612 -> 273 chars, body 1124 -> 457 words. Branch patterns,
operations, merging, comparison, and the orchestrator contract move to
references/.
Corrects rebase routing in four places: this skill sent rebase to
git-history, which carries no rebase content and disclaims it. Rebase is
git-commits'; cherry-pick and revert stay git-history's. Drops a Step 3
gate on a rebase flow this skill does not have.
