/**
 * #2284 — Hermes named-dispatch → delegate_task projection.
 *
 * The Hermes installer previously only brand-swapped "Claude Code" →
 * "Hermes Agent" in shipped `gsd-core/workflows/*.md`, leaving a false
 * "The Agent tool IS available" assertion and literal `Agent(...)` call
 * syntax installed verbatim — Hermes exposes `delegate_task`, not `Agent`.
 *
 * Covers:
 *   1. Direct converter contract — projectNamedDispatchToStructuralDelegate /
 *      convertClaudeToHermesMarkdown against representative fixture prose,
 *      across ALL THREE real corpus call-argument shapes: multi-line
 *      one-key-per-line, single-line object-literal (`Agent({...})` —
 *      import.md/ingest-docs.md), and single-line compact
 *      (`Agent(subagent_type="x", model="y", prompt="...")` —
 *      code-review-fix.md/ship.md/etc).
 *   2. Real disposable-HOME `--hermes --global` e2e install — no literal
 *      `Agent(` survives, `delegate_task` is present, commands→skill path
 *      (convertClaudeCommandToClaudeSkill) still works unregressed; spot-
 *      checks import.md, ingest-docs.md, and code-review-fix.md specifically
 *      (the object-literal and single-line-compact sites).
 *   3. Fail-closed role resolution — a referenced gsd-* role prompt missing
 *      from the shipped agents/ directory aborts install with an explicit
 *      error, in EVERY call-argument shape, both at the converter level and
 *      through the real install path (deterministic fs.readdirSync
 *      injection per the repo's cross-platform IO-failure-injection
 *      convention — never chmod/permission tricks).
 *   4. The post-projection guard (belt-and-suspenders) — fails loud on any
 *      residual subagent_type / leaked model= / unprojected Agent( the
 *      projection above did not anticipate, rather than silently shipping it.
