v2.1 — obsidian-ledger: universal agent integration

obsidian-ledger 0.1.0 — a symbolic fact ledger for Obsidian vaults that any coding agent can trust (Claude Code, Codex, Gemini CLI, Cursor, Windsurf, OpenCode, ...).

• 4 integration layers: vault files, instruction blocks (AGENTS.md/CLAUDE.md/GEMINI.md/.cursorrules/.windsurfrules), CLI, zero-dependency MCP stdio server
• verify verdicts: SUPPORTED / CONTRADICTED_STALE / CONTRADICTED_CURRENT / NOT_IN_LEDGER — the anti-hallucination primitive
• Tested end-to-end on a third-party public vault (kepano-obsidian: 76 cards, 3.5min, $0.02, 2 real bugs found and fixed)
• Install now: pip install https://github.com/caiovicentino/cls-ledger/releases/download/v2.1/obsidian_ledger-0.1.0-py3-none-any.whl (PyPI pending account-scoped token)
