Copilot installs agent files as gsd-*.agent.md (not gsd-*.md), so
checkAgentsInstalled() always returned agents_installed=false for Copilot.
- checkAgentsInstalled() now recognises both .md and .agent.md formats
- getAgentsDir() respects GSD_AGENTS_DIR env override for testability

When GSD agents are not installed in .claude/agents/, Task(subagent_type="gsd-*")
silently falls back to general-purpose, losing specialized instructions, structured
outputs, and verification protocols.
What changed:
- Added checkAgentsInstalled() to core.cjs that validates all expected agents exist on disk
- All init commands now include agents_installed and missing_agents in their output
- Health check (validate health) reports W010 when agents are missing or incomplete
- New validate agents subcommand for standalone agent installation diagnostics
Fixes#1371
