refactor: remove turn tools, rename discord tools, rewrite installer

- Remove turn management tools (turn-status/advance/reset) — internal only,
  accessible via /dirigent slash commands
- Rename discord tools: dirigent_discord_channel_create,
  dirigent_discord_channel_update, dirigent_discord_member_list
- Rewrite install script:
  - Dynamic OpenClaw dir resolution (OPENCLAW_DIR env → openclaw CLI → ~/.openclaw)
  - Plugin installed to $(openclaw_dir)/plugins/dirigent
  - New --update mode: git pull from latest branch + reinstall
  - Cleaner uninstall: removes installed plugin files
- Update docs (FEAT.md, README.md, CHANGELOG.md, TASKLIST.md)
