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

+name: defuddle
+description: "Strip clutter from web pages before ingesting into the wiki. Removes ads, navigation, headers, footers, and boilerplate — leaving clean readable markdown that saves 40-60% tokens. Triggers on: defuddle, clean this page, strip this url, fetch and clean, clean web content before ingesting."
+---
+
+# defuddle — Web Page Cleaner
+
+Defuddle extracts the meaningful content from a web page and drops everything else: ads, cookie banners, nav bars, related articles, footers, social sharing buttons. What remains is the article body as clean markdown.
+
+Use this before any URL ingestion. It is optional but strongly recommended — it cuts token usage by 40-60% on typical web articles and produces cleaner wiki pages.
+
+---
+
+## Install
+
+```bash
+npm install -g defuddle-cli
+```
+
+Verify: `defuddle --version`
+
+---
+
+## Usage
+
+### Clean a URL directly
+```bash
+defuddle https://example.com/article
+```
+Outputs clean markdown to stdout.
+
+### Save to .raw/
+```bash
+defuddle https://example.com/article > .raw/articles/article-slug-$(date +%Y-%m-%d).md
+```
+
+### Add frontmatter header after saving
+After running defuddle, prepend the source URL and fetch date:
+```bash
+SLUG="article-slug-$(date +%Y-%m-%d)"
+{ echo "---"; echo "source_url: https://example.com/article"; echo "fetched: $(date +%Y-%m-%d)"; echo "---"; echo ""; defuddle https://example.com/article; } > .raw/articles/$SLUG.md
+```
+
+### Clean a local HTML file
+```bash
+defuddle page.html
+```
+
+---
+
+## When to Use
+
+**Use defuddle when:**
+- Ingesting a news article, blog post, or documentation page from a URL
+- The page has a lot of surrounding content (most web pages do)
+- You want to stay within token budget on a long article
+
+**Skip defuddle when:**
+- The source is already a clean markdown or PDF file
+- The page is a dashboard, app, or structured data (defuddle expects article-style content)
+- defuddle is not installed and the article is short enough to process raw
+
+---
+
+## Fallback
+
+If defuddle is not installed, check:
+
+```bash
+which defuddle 2>/dev/null || echo "not installed"
+```
+
+If not installed: use WebFetch directly. The content will be less clean but still workable.
+
+---
+
+## Integration with /wiki-ingest
+
+The `/wiki-ingest` skill checks for defuddle automatically when a URL is passed. You do not need to run defuddle manually before ingesting a URL — the ingest skill will call it if available.
+
+To manually clean a page and save before ingesting:
+1. Run the save command above
+2. Then: `ingest .raw/articles/[slug].md`
