integration: Obsidian plugin

[devswha]

Why it matters

Obsidian (~1M+ users) is the densest concentration of "write a lot, care about voice" users on the planet. Patina's brand voice aligns directly with the "personal voice / second brain" framing.

Acceptance criteria

• New repo devswha/patina-obsidian using sample plugin template
• Command palette: Score current note, Audit current note, Humanize selection
• Status bar score
• Settings: language, backend, CLI path
• Submit to obsidian-community-plugins registry
• Depends on npm-publish

Wave 4 triage: this stays open.

Concrete blocker: an Obsidian plugin needs a separate plugin package/repo, manifest/release workflow, vault-safety review, and community-plugin submission path. That is outside the current repo-only documentation/integration wave.
