Follow-ups from PR #113 review (CHANGELOG missing reference links)

[liam-ai-reality]

Follow-up from the review comment on PR #113 (#issuecomment-4457579437).

Pre-existing missing footer reference links

Three issue/PR numbers are cited in the CHANGELOG body but have no corresponding footer reference link, so the [#N] text does not render as a hyperlink on GitHub.

Do next

• [#91] — used in ## [0.3.1] (klasp gate accepts --agent/--trigger flags). Add: [#91]: https://github.com/klasp-dev/klasp/issues/91 (or /pull/91 if it was a PR).
• [#72] — used in ## [0.2.3] (pre_commit and fallow recipes scope fix). Add: [#72]: https://github.com/klasp-dev/klasp/pull/72
• [#73] — used in ## [0.2.3] (klasp doctor respects [gate].agents). Add: [#73]: https://github.com/klasp-dev/klasp/pull/73

These can land in a single one-line-per-fix commit: docs(changelog): add missing footer reference links (#72, #73, #91).
