Add Woodpecker CI + retroactive CHANGELOG

Message

- .woodpecker.yml: minimal pipeline that fetches the pinned sigil release binary, runs sigil deps install, then sigil test on push + PR. Pinned to v0.13.1; bump via search/replace per release. - CHANGELOG.md: Keep-a-Changelog file with one section per existing tag, derived from git log <prev>..<tag> walks.

# Woodpecker CI configuration for Codeberg

# https://docs.codeberg.org/ci/

#

# Library CI: fetch a stable sigil binary, install deps via from-git

# pins, run the test suite. Pinning to a sigil release rather than

# `dev` keeps CI stable when the monorepo is in flight; bump the

# pin via search/replace when a new release is cut.
