Summary by cubic

Adds a reference note distilling Cumora's multi-agent coordination playbook, plus a small SiteStats.astro type fix so branches cut from main pass type checks. This PR is for reference review and is not intended to be merged.

Note content

• Documents two failure modes — race collisions (code-fixable) and brain misjudgment (prompt-level) — and the rule to fix with code mechanisms before adding prompt rules.
• Covers seven defense layers: model pinning, concurrency gates, deterministic spawn spacing, freshness preflight, atomic in-transaction de-duplication, and a small standing prompt.
• Lists twelve anti-patterns with commit references, including only capping one layer of a shared provider and piling scenario examples into prompts.
• Maps lessons to our memory hooks and herdr multi-agent relay, and references the seen-cursor contract and diff-against-last-good-baseline debugging.

^{Written for commit 8f86087. Summary will update on new commits.}

<violation number="1" location="src/content/notes/0926-cumora-multi-agent-coordination.md:3">
P3: The description claims the note covers 十二条反模式 (twelve anti-patterns), but the 反模式清单 section enumerates only seven bullets: only-cap-one-layer, piling scene examples into prompts, pouring persona/CLI-directory into standing prompt, fixing infra with prompt changes, hammering converged LLM judgment, treating absent members as faults-to-fix, and diff-vs-last-good baseline. Either the count is wrong or five anti-patterns are missing from the body. Reconcile the number with the enumerated list so the note's summary matches its content.</violation>

<violation number="2" location="src/content/notes/0926-cumora-multi-agent-coordination.md:3">
P3: The `description` (and intro framing) claims "十二条反模式", but the 反模式清单 section lists only 7 anti-patterns (counting the bullets). The note never acknowledges the remaining 5. Either drop the count from the description or note that the section extracts a subset, so the summary matches the body.</violation>

P3: This note is published without a `.en.md` mirror, while all 22 existing notes ship as Chinese `.md` + English `.en.md` pairs (the config keeps the pair in sync).
