chore: add CHANGELOG.md and FUNDING.yml (#33)

- CHANGELOG.md: Keep-a-Changelog format starting at v0.0.1 (initial
scaffold) with an Unreleased section tracking Phase 1 remaining work
- .github/FUNDING.yml: placeholder funding config — fills in when GitHub
Sponsors or Open Collective is set up; GitHub will show a "Sponsor"
button on the repo
