feat: v1.1 — URL ingestion, vision, delta tracking, 3 new skills, auto-commit

Skills (new):
- skills/obsidian-markdown/ — full Obsidian Flavored Markdown syntax reference
  (wikilinks, embeds, callouts, properties, math, Mermaid)
- skills/obsidian-bases/ — Obsidian Bases (.base files) with correct filters/views/
  formulas syntax (sourced from kepano/obsidian-skills authoritative spec)
- skills/defuddle/ — web page cleaner; strips ads/nav before URL ingestion,
  saves 40-60% tokens on web articles

wiki-ingest upgrades:
- URL ingestion: pass https:// directly, auto-fetches + runs defuddle if available
- Image/vision ingestion: .png/.jpg/.gif etc → Claude reads → description saved
  to .raw/ → standard ingest pipeline
- Delta tracking: .raw/.manifest.json tracks hash per source, skips unchanged files

wiki-query upgrades:
- Quick mode (query quick:) — hot.md + index only, ~1500 tokens
- Standard mode — existing behaviour, 3-5 pages
- Deep mode (query deep:) — full wiki + optional web search supplement

hooks:
- PostToolUse auto-commit: every Write/Edit to wiki/ or .raw/ triggers
  git add + commit automatically, vault always versioned

fixes:
- Removed invalid allowed-tools field from all 10 SKILL.md files
  (not a valid skill frontmatter attribute per spec; was silently ignored)
- Canvas SKILL.md now references json-canvas open standard and kepano/obsidian-skills

wiki research:
- Ecosystem research: 16+ Claude+Obsidian projects mapped and filed
- New pages: comparisons/claude-obsidian-ecosystem, concepts/cherry-picks,
  entities/ (6 new), sources/claude-obsidian-ecosystem-research
- Cherry-picks roadmap filed at wiki/concepts/cherry-picks.md

+A canvas is a JSON file Obsidian renders as an infinite visual board. This skill reads and writes canvas JSON directly. Read `references/canvas-spec.md` for the full format reference before making any edits. This spec aligns with the [JSON Canvas open standard](https://jsoncanvas.org/) — if `kepano/obsidian-skills` is installed, its `json-canvas` skill is the authoritative cross-platform reference.
