Refactor and harden the unified Node installer and related docs. Major changes:
- bin/install.js: validate --only ids, expand ~ for --config-dir, make Claude/install flows async (await hooks/init), add many CLI flags (--no-mcp-shrink, --with-hooks/--no-hooks, --skip-skills, --config-dir docs), preserve original backups once, avoid overwriting plugin/command files unless --force, and add opencode AGENTS.md fenced begin/end markers so installs/uninstalls can append/strip cleanly. Also add opencode idempotency probes for claude/gemini uninstall paths and better handling of opencode plugin payload.
- bin/lib/settings.js: safer removeCavemanHooks that validates shapes before mutating hooks.
- runInit/installHooks/downloadTo calls made async and awaited; runInit returns promise now.
- Docs and README/INSTALL/CONTRIBUTING/CLAUDE.md/src/hooks/README.md: update user-facing text to match new flags/behaviour, standardize use of $CLAUDE_CONFIG_DIR, clarify --with-init semantics, and note opencode/openclaw handling. Change command name usages from `/caveman:compress` to `/caveman-compress`.
- opencode: write fenced caveman block to AGENTS.md and handle legacy unfenced blocks; tests updated to expect fence markers.
These changes improve idempotency, safer upgrades/uninstalls, clearer UX around per-repo vs per-user init, and make the opencode rule block removable without destroying user content.
Replaces opencode's Tier-4 npx-skills entry with a native in-repo plugin
that mirrors the Claude Code hook architecture (session.created +
tui.prompt.append) using opencode's lifecycle hook system. Reaches Tier-1
parity minus the statusline (opencode TUI exposes no plugin-writable
badge). Skill files drop in unchanged — opencode reads SKILL.md natively.
Plugin reuses src/hooks/caveman-config.js for the symlink-safe flag-write
helpers via createRequire (renamed .cjs post-install to coexist with the
plugin dir's "type":"module"). AGENTS.md provides a Tier-3 always-on
fallback if the plugin runtime breaks.
5 new tests cover fresh install, idempotency, JSONC tolerance of
pre-existing opencode.json, uninstall, and a plugin smoke test that fires
synthetic tui.prompt.append events. All 38 installer tests pass.
