/**
 * Parity test for bug #373: space-safe gsd_run launcher
 *
 * Asserts:
 * (A) No retired GSD_SDK token remains in any workflow .md file.
 * (B) Each workflow .md that uses gsd_run contains EXACTLY ONE canonical preamble
 *     (byte-equal to _runtime-launcher.snippet.sh), and it appears before the first
 *     gsd_run call. NOT every bash block — exactly one per file (define once, use
 *     across blocks — original footprint).
 * (C) Space-safe behavioral: a RUNTIME_DIR path with spaces in it resolves
 *     and calls gsd-tools.cjs correctly (no word-split, no {}).
 * (D) Loud guard behavioral: missing gsd-tools.cjs exits non-zero and emits
 *     "not found" to stderr.
 * (E) PATH fallback behavioral: when no local gsd-tools.cjs, the elif branch
 *     resolves to the gsd_run binary on PATH (#3668).
 * (F) Regression locks: the snippet file contains no /gsd-tools substring; and
 *     no line in workflows/do.md matches /\/gsd[:-][a-z]/ (dispatcher-parity
 *     scanner must not read the preamble as a slash-command stub).
 * (H) Codex shim fallback: when PATH has no gsd_run, $HOME/.codex/gsd-core/bin
 *     can satisfy gsd_run for Codex shim-only installs.
