feat(omo-claude): re-vendor MCP servers self-contained with CLAUDE_PLUGIN_ROOT

ast_grep + lsp servers vendored under plugin/mcp via sync-mcp.mjs; .mcp.json uses
${CLAUDE_PLUGIN_ROOT} (no ../). Both boot from a node_modules-free tree (verified
JSON-RPC initialize handshakes). lsp hook bundled to inline lsp-tools-mcp. mcp/
dist is gitignored (regenerated by build).
