v0.2.0 — Federation, richer surfaces, portable build

The v0.2 slice. All additive — the default cargo build keeps the full macOS experience.

Highlights

• NATS federation — event bus (F1): opt-in [nats] + the new entheai-bus crate publish every --fanout run's lifecycle to entheai.fanout.<session>.* for any tailnet subscriber. Fail-safe; the orchestrator stays NATS-agnostic.
• entheai --skills add <url>: install a skill from the web via layered discovery (/.well-known/skills.json → /llms.txt → the page). Path-traversal-safe, SSRF-guarded, bounded, skip-if-exists.
• Obsidian wiki-sync: per-session, fail-safe sync of the repo into an Obsidian vault ([obsidian]).
• Native app: entheai --app (minimalist Ghostty window) and entheai --doctor (installs the rain-on-glass shader into your Ghostty config).
• Live swarm visualization: inline ratatui swarm graph during fan-out (Ctrl-V / /viz, /workers).
• entheai --memory list|search|stats, the entheai-mapper task router, and a broad config surface.

Changed

• Portable headless build: GUI + audio are default features; cargo build --no-default-features builds with zero system libraries; sentry → rustls.

Fixed

• Fan-out v2 used the read-only decompose prompt (edit tasks became explore-only) — now coder-oriented with a guaranteed coder.
• Bounded external inputs (MCP/shell/file timeouts + caps).

Performance

• Borrowed provider messages/tools (drop per-turn O(n²) clones), TUI per-message line cache, Obsidian mtime read cache.
