chore(oss): add PR template, CODEOWNERS, CHANGELOG (supersedes #22)

[flyingrobots]

This consolidates the OSS hygiene from #22 on top of current main without risky rebase/merge conflicts.\n\n- Adds .github/pull_request_template.md (aligns with AGENTS.md guidance)\n- Adds CODEOWNERS (default to @flyingrobots)\n- Adds CHANGELOG.md (Keep a Changelog format)\n\nNotes\n- No workflow edits here; CI matrices already Ubuntu-only in main (macOS dropped to control spend).\n- Closes #22 as superseded once merged.

• Ratify: owner approval guardrails (CODEOWNERS + required check) shiplog#29 — Also adds .github/pull_request_template.md and a CODEOWNERS file with @flyingrobots ownership; same metadata theme and scope.

Poem

New forms for every change we send,
A watchful owner to the end.
No code was touched, you drama queens—
Just guardrails, checklists, crisp routines.
Ship it clean, or don’t ship at all.
