Extends the canonical runtime-launcher snippet with a third resolution arm
that probes $HOME/.claude/get-shit-done/bin/${_GSD_SHIM_NAME} between the
PATH check and the hard-error exit. Global Claude-Code installs (--claude
without --local) with no PATH wiring and no RUNTIME_DIR no longer hit the
hard-error path.
Resolution order: local/RUNTIME_DIR -> PATH -> ~/.claude/... -> hard error.
Propagated to 76 workflow .md files via sync-runtime-launcher.cjs. Parity
test (G) and bug-211 regression test (4 assertions) added.
