* fix(#384): make getAgentsDir runtime-aware so non-Claude installs find agents

getAgentsDir() ignored the active runtime and always returned the
claude-family __dirname-relative agents path, so on OpenCode (and other
non-Claude runtimes) checkAgentsInstalled() looked in the wrong directory
and reported agents missing even when installed. Resolve the per-runtime
global config dir via getGlobalConfigDir(runtime) (GSD_AGENTS_DIR env >
runtime arg > GSD_RUNTIME env > 'claude'), and surface agent_runtime and
agents_dir through withProjectRoot() so init diagnostics show which
directory was checked. Updates the stale W010 health-check test that
relied on the old __dirname path.

* chore(#384): set changeset pr to 617

* fix(#384): keep claude on __dirname agents path; fix test lint + leak

Address CI failures on the first cut:
- getAgentsDir now only routes NON-claude runtimes through
  getGlobalConfigDir(runtime); claude retains the original __dirname-
  relative agents path, which correctly resolves to <repo>/agents for
  repo runs and the runtime config agents dir for real installs. This
  restores validate-health / W010 checks that were regressing because the
  claude default had moved off the repo-relative path.
- Revert the now-unneeded GSD_AGENTS_DIR workaround in
  agent-install-validation.test.cjs (back to its next state).
- bug-384 test: use helpers.cleanup() instead of raw fs.rmSync()
  (local/no-raw-rmsync-in-tests) and drop an unused var.
- Reword a doc comment that contained a literal ~/.claude/agents path,
  which tripped the cline-install no-leaked-paths scanner.
