v0.7.2 — hotfix-flow Step 7 fix + CHANGELOG backfill

[0.7.2] - 2026-05-10

Follow-up to a retrospective pr-review pass on #7: the hotfix-flow skill's Step 7 no longer prescribes a git merge --no-ff forward-merge that a required_linear_history / protected main (this repo's own, for one) would reject, and the [0.5.0]–[0.7.1] CHANGELOG entries get the PR references they were missing. No skill behavior change beyond the Step 7 wording. Patch release.

Fixed

• skills/hotfix-flow/SKILL.md Step 7 no longer prescribes git merge --no-ff for repos with linear history (#11) — the forward-merge step gave git merge --no-ff hotfix/… as the default command, which a required_linear_history / protected main (like this repo's own) rejects; Step 7 and its edge-case row now spell out that on such repos the forward-merge goes through a PR with a rebase/squash merge, keeping --no-ff only as the "repo allows merge commits" path. Surfaced by running the pr-review skill retrospectively on #7.

Changed

• CHANGELOG.md — PR references backfilled on the [0.5.0]–[0.7.1] entries (#11) — the primary bullet of [0.5.0] / [0.6.0] / [0.7.0] / [0.7.1] now carries (#3) / (#5) / (#7) / (#9), matching the (#init) / (#1) convention on [0.1.0] / [0.4.0]; these had been missing the PR ref that pr-review Step 5 / changelog-bot Step 2 require.
