Codeep

Patch: /mcp now works in the CLI TUI (was only wired into the ACP path
in 2.0.0, so Zed and VS Code worked but codeep direct didn't). Full
subcommand parity — browse, install, add, remove, reload, resources,
read, prompts, prompt.

Fixed

• /mcp slash command in CLI TUI returned Unknown command: /mcp.
  The 2.0.0 implementation lived only in src/acp/commands.ts, so it
  worked for ACP clients (Zed, VS Code extension) but TUI users hit the
  unknown-command path. Ported the full handler to
  src/renderer/commands.ts with TUI-appropriate output (uses the fixed
  codeep-tui session id and ctx.projectPath as workspace root).
  Subcommands now usable from the TUI: /mcp, /mcp browse [id],
  /mcp install <id> [args...], /mcp add <name> <command> [args...],
  /mcp remove <name>, /mcp reload, /mcp resources,
  /mcp read <uri>, /mcp prompts, /mcp prompt <server> <name> [k=v].
• Eight 2.0 commands missing from / autocomplete and /help —
  /mcp, /compact, /checkpoint, /checkpoints, /rewind, /hooks,
  /openrouter, /commands were all implemented but invisible to
  discovery. Added to App.COMMANDS + COMMAND_DESCRIPTIONS so they
  appear when the user types /, and added two new /help sections
  ("Checkpoints (2.0)", "Extensions & MCP (2.0)") plus /compact
  under Sessions and /openrouter under Settings.
• /skills publish rejected global bundles. The helper required
  bundle.scope === 'project', blocking a common case: user writes a
  cross-project skill once in ~/.codeep/skills/<name>/ and tries to
  share it. The --public flag is the user's explicit consent gate,
  so an extra scope check is redundant gatekeeping. Now publishes
  project OR global bundles; project wins on slug collision (mirrors
  loadSkillBundles). Error message also clarifies both lookup
  paths when the slug isn't found anywhere.
