feat(cli): 1.5.0 — CLI-first architecture, tool-less MCP, policy engine

CLI becomes the API; MCP becomes a tool-less push-pipe. Bundle -42%
(250 KB → 146 KB) after stripping ~1700 lines of dead tool handlers.

- Tool-less MCP: tools/list returns []. Inbound peer messages still
  arrive as experimental.claude/channel notifications mid-turn.
- Resource-noun-verb CLI: peer list, message send, memory recall, etc.
  Legacy flat verbs (peers, send, remember) remain as aliases.
- Bundled claudemesh skill auto-installed by `claudemesh install` —
  sole CLI-discoverability surface for Claude.
- Unix-socket bridge: CLI invocations dial the push-pipe's warm WS
  (~220 ms warm vs ~600 ms cold).
- --mesh <slug> flag: connect a session to multiple meshes.
- Policy engine: every broker-touching verb runs through a YAML gate
  at ~/.claudemesh/policy.yaml (auto-created). Destructive verbs
  prompt; non-TTY auto-denies. Audit log at ~/.claudemesh/audit.log.
- --approval-mode plan|read-only|write|yolo + --policy <path>.

 # claudemesh-cli
 
-Peer mesh for Claude Code sessions. Connect multiple Claude Code instances into a shared mesh with real-time messaging, shared state, memory, file sharing, and 79 MCP tools.
+Peer mesh for Claude Code sessions. Connect multiple Claude Code instances into a shared mesh with real-time messaging, shared state, memory, file sharing, vector store, scheduled jobs, and more — all driven from the `claudemesh` CLI. The MCP server is a tool-less push-pipe that delivers inbound peer messages to Claude as `<channel>` interrupts; everything else lives behind CLI verbs that Claude learns from the auto-installed `claudemesh` skill.
+
+> **Migration note (1.5.0):** the previous 79 MCP tools (`send_message`, `list_peers`, `remember`, …) are removed. Use the matching CLI verbs (`claudemesh send`, `claudemesh peers`, `claudemesh remember`). Run `claudemesh install` and the bundled skill teaches Claude the full surface.
