docs(changelog): promote the Unreleased entries under 0.1.1

[maybebyte]

Summary

copier update targets the latest SemVer tag rather than HEAD, so none of the template fixes merged since June reach a downstream project until a tag exists — and main is 76 commits past v0.1.0. This cuts the release commit so v0.1.1 can be tagged.

Changes

• Promotes the [Unreleased] entries under ## [0.1.1] - 2026-08-04 and adds the compare-link references, per the Release section of AGENTS.md.
• Patch, not minor. All eight commits touching template/ or copier.yml since v0.1.0 are fix(template) or docs(template); there is no feat among them. The two Changed entries remove dead generated config (the [tool.ruff.lint.mccabe] block, the gitleaks mise pin) and were themselves authored as fixes.
• No template or code changes ride along — the diff is CHANGELOG.md only.

Testing

• Docs-only change; no automated tests apply. The changelog was cross-checked against git log v0.1.0..HEAD -- template/ copier.yml — 8 commits, all covered by the 7 promoted entries (the shallow-checkout fix is folded into the gitleaks entry).
• The maintainer-only dogfooding work merged in the same window (gaps docs(specs): add dependency-inventory design spec #1–docs(plans): add dogfooding-gap audit of shipped guardrails #5, feat(audit): dogfood the pip-audit dependency-audit gate on the maintainer repo #8) is deliberately absent: it changes nothing downstreams receive.

Notes for reviewers

• Merging does not release anything. The tag is a separate step and must be applied to the merge commit on main:
  git tag -a v0.1.1 -m "v0.1.1" && git push origin v0.1.1, then git describe --tags to confirm a reachable tag exists.
• Until that tag is pushed, downstream projects stay on v0.1.0 and just deps-template-style HEAD renders remain the only way to see the current template.
• Decision: this release is being cut before enabling the Mend Renovate app, so the tagged tree contains no bot-authored commits and stays a clean bisect baseline for "did a dependency bump break the template contract" — see the amended Sequence in docs/superpowers/specs/2026-06-25-dependency-inventory-design.md (PR docs(specs): correct the renovate design after adversarial review #11).
