chore(continuity): record program complete + v0.3.0; capture F6 lessons

[jimCresswell]

What & why

Session closeout for the completed "highest proportionate bar" program (v0.3.0 cut).

• repo-continuity.md + gate-expansion thread record: refreshed to mark the program complete, list what landed (F6 feat(safety): close pipe and substitution bypasses in agent hook (F6) #37, Tier 3 test(coverage): branch coverage + honest floor 86 (Tier 3) #38/test(boundary): Hypothesis property tests for the data boundary (Tier 3) #39/docs(adr): single bleeding-edge Python version policy (Tier 3, ADR-0002) #40, Tier 2 docs(governance): owner-action checklist (Tier 2) #41, Dependabot build(deps): bump the github-actions group with 3 updates #29/build(deps): bump the python-dependencies group across 1 directory with 14 updates #30, release chore(release): v0.3.0 #25), and record that the only remaining work is owner-only GitHub settings and the documented F6 residuals (glued operators, bare subshells, heredoc-prose over-block).
• napkin: captures the load-bearing lesson — a safety guardrail must prefer over-blocking to under-blocking. The reverted heredoc-strip would have let a bash-fed quoted heredoc force-push slip (a quoted delimiter blocks expansion, not execution).

Operational-memory only; no code or behaviour change.
