Liminal 0.0.20 — Vault knowledge graph & desktop provider presets

v0.0.20 turns the Obsidian vault into a connected entity brain — one dossier per person, org, or event with vault_ingest_entities and GraphRAG-style vault_recall — and makes Liminal Desktop easier to configure with provider presets (including Owl Alpha Stealth). When managed inference credits run out, the harness can fall back to your OpenRouter BYOK key on a free model instead of failing the turn.

Shipped in this slice#

• Vault knowledge graph — vault_ingest_entities splits research into per-entity notes; vault_ingest weaves [[wikilinks]]; vault_recall returns linked neighborhoods; vault_lint finds orphans; auto-write uses entity extraction on research turns
• R-VAULT-ENTITIES — Protocol teaches one canonical name per dossier, parallel vault_write for batches, and event+cast workflows (tags: person, org, …)
• Managed inference fallback — HTTP 402 or empty wallet → OpenRouter BYOK on openrouter/owl-alpha when AGENT_MANAGED_FREE_FALLBACK=1; desktop loads API keys from bundled .env
• Desktop Settings — Provider preset dropdown aligned with web; save model/base URL without re-entering API key every time
• Web — Shared provider presets from core; inference banner when credits are exhausted
