feat(omo-claude): scaffold package skeleton

Mirror packages/omo-codex layout for the Claude Code port: package.json
(@oh-my-opencode/omo-claude), tsconfig, index.d.ts, src/ + src/telemetry
stubs, and the plugin/ tree (.claude-plugin, components, agents, hooks,
scripts, skills, test, mcp) with a CC-worded plugin README + placeholder
package.json.

Plan: .omo/plans/omo-claude-plugin-port.md

+# omo
+
+`omo` is the single local Claude Code plugin namespace for Yeongyu's Claude Code components.
+
+Internally each component remains isolated under `components/`:
+
+- `components/comment-checker`
+- `components/rules`
+- `components/lsp`
+- `components/ultrawork`
+- `components/ultragoal`
+- `components/start-work-continuation`
+- `components/telemetry`
+
+The root plugin manifest (`.claude-plugin/plugin.json`) exports one Claude Code plugin
+named `omo`, with aggregate hooks (`hooks/hooks.json`), bundled skills (`skills/`),
+subagents (`agents/`), and the LSP + ast-grep MCP servers (`.mcp.json`).
