Generate degraded-mode fallback references from the subagent definitions

Harnesses with no subagent capability now run each role inline from the
same single source. The build emits reference/degraded/<role>.md for every
agent in skill/agents/ (role name is the agent name minus the impeccable-
prefix), stripping frontmatter and prepending the inline-substitution
preamble. These pass through the same provider-block compilation and
placeholder replacement as ordinary reference files, so <codex> blocks and
{{placeholders}} resolve per target, and they land in the committed harness
dirs on build:release like every reference file.

Repoint the three capability-first fallback sites in the prose at the
generated files: new-work.md reviewer and documenter fallbacks, and
visualize.md asset-producer fallback.

 Inspect desktop and mobile in one batched screenshot round, critique the render against the user's request and the direction contract, fix material gaps, and confirm with one final round; two rounds is the ceiling, and fixes batch between them rather than earning per-tweak screenshots. On a Persuade surface, verify the mode did its job: a first-time visitor should know what this is, why it matters, and what to do within seconds, in the form's own vocabulary.
 
-After the second inspection round the build thread's polishing is over: no further defect hunts, micro-edit scripts, or rebuilds here; whatever remains ships through the handoffs, where a fresh context does the finding better and cheaper. Capture desktop and mobile screenshots to files, then spawn the shipped finish reviewer, `impeccable-finish-reviewer` (`impeccable_finish_reviewer` in codex), with the original request, confirmed answers, the artifact path, the screenshot paths, its direction contract, existing hook findings, and the QUALITY BAR card and approved comp paths. The reviewer has no browser; screenshots you fail to pass are checks it cannot run. Verify its return carries the five contract sections; on an empty or thrashed return, respawn once with the same inputs before doing anything else. This review never runs inside the build thread. Only a harness whose tool surface has no subagent capability at all substitutes a fresh in-thread pass after stepping fully out of the build context, and a substituted or failed-and-replaced review is disclosed in one line at finish, never silently. Apply the material fixes in one batch, rebuild once, and stop; the reviewer ran so that you do not re-open your own hunt. Do not run a second detector. <!-- rule:skill-finish-separate-reviewer -->

 ## Produce only the assets the build needs
 
-When clean raster ingredients are required and the harness runs subagents, use the shipped asset producer, `impeccable-asset-producer` (`impeccable_asset_producer` in codex): give it the approved comp, output paths, required dimensions and formats, transparency needs, crop notes, and what must remain semantic code. Otherwise produce the minimum required assets in the current thread with whatever generation exists, the native tool or generate-image.mjs.
