feat(install): add AdaL CLI install target

Following the hermes/openclaw (#2433) and kimi (#2441) adapter recipe.

What's included (adal-project adapter, project kind, ./.adal root, same
shape as kimi-project/joycode-project):
- scripts/lib/install-targets/adal-project.js — 10-line project-kind
  adapter targeting ./.adal
- Registry + helpers platform-ownership wiring
- adal target on the 5 shared modules (rules-core, agents-core,
  commands-core, platform-configs, workflow-quality) +
  SUPPORTED_INSTALL_TARGETS + legacy-compat module
- .adal in platform-configs paths
- Both schema enums (install-modules, ecc-install-config), npm files
  allowlist, installer help text, .adal/README.md stub

AdaL (adalagent.ai) is a terminal-based AI coding agent (by SylphAI)
built on AdalFlow, with native MCP support and project-scoped config
under ./.adal/ (skills, custom tools, memory) plus a root-level
AGENTS.md instructions file — matching the shape ECC already installs
into other AGENTS.md-based harnesses (Codex, OpenCode, Kimi).

Verified: full suite matches main's baseline (3334 passed, same
pre-existing failures unrelated to this change — OpenCode build/npm-pack
surface tests requiring build tooling not present in this sandbox);
catalog check passes (67 agents / 94 commands / 281 skills); dry-run
resolves Target: adal / Adapter: adal-project / root ./.adal with all 5
modules planned; doctor reports OK after a real install; uninstall
cleanly reverses all 458 operations.
