/**
 * Bug #2851: plan-phase.md §13e calls bare `gsd-tools` — incomplete fix of #2245
 *
 * Workflow bodies should not call `gsd-tools` as an unguarded bare command.
 * Use the resolver snippets for SDK calls, or an explicit local CJS path when
 * a command intentionally targets the checked-in legacy script:
 *
 *   node "$HOME/.claude/gsd-core/bin/gsd-tools.cjs" <subcommand> [args]
 *
 * Some workflow markdown files leaked the bare `gsd-tools <subcommand>` form,
 * which fails with `command not found` at runtime.
 *
 * This test parses every markdown file in gsd-core/workflows/ structurally:
 * it tokenizes the content into fenced code blocks, then on each shell-block
 * line checks whether `gsd-tools` appears as a bare command (not preceded by
 * `node `, not part of the filename `gsd-tools.cjs`, not inside a comment).
 *
 * Per project rule: this test does NOT use grep/regex .includes() on raw file
 * content as the assertion surface. Instead, it splits into code-fenced blocks
 * and tokenizes each line — only command-position tokens count as violations.
