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

+# Claudian (YishenTu/claudian)
+
+**Type**: Native Obsidian plugin (TypeScript, embedded Claude Code/Codex)
+**URL**: https://github.com/YishenTu/claudian
+**Install**: BRAT or manual (not yet in community store)
+
+## What It Does
+
+Embeds Claude Code (or Codex CLI) directly inside Obsidian as a sidebar chat. The vault becomes the agent's working directory — all Claude Code tools work natively inside Obsidian.
+
+## Key Features
+
+### Inline Edit with Word-Level Diff
+Select text in a note + hotkey → Claude proposes edit with word-level diff preview → one-click apply. Best-in-class inline editing in the Obsidian AI ecosystem.
+
+### Plan Mode (Shift+Tab)
+Agent explores and designs before implementing. Presents a plan for approval before any file changes. Mirrors Claude Code's own plan mode.
+
+### @mention System
+Type `@` to reference:
+- Vault files
+- Sub-agents
+- MCP servers
+- Files in external directories (outside vault)
+
+### Instruction Mode (#)
+Add refined custom instructions directly from chat input — persisted for the session.
+
+### MCP Server Integration
+Connect external tools via stdio, SSE, or HTTP. Claude manages vault MCP in-app; Codex uses CLI-managed config.
+
+### Multi-Tab Conversations
+Multiple chat tabs, conversation history, fork, resume, compact mode.
+
+## Privacy
+- No telemetry
+- Settings stored in `vault/.claudian/`
+- Claude files in `vault/.claude/`
+- Transcripts in `~/.claude/projects/`
+
+## Relevance to claude-obsidian
+Claudian is a native plugin (different category) but its Plan Mode, @mention, and inline edit patterns could inspire new features in claude-obsidian skills — particularly for the canvas and wiki-query workflows.
