fix(kyberforge): resolve clean-context audit findings on primitive support

primitive-author:
- description excludes read-only review (-> factory-audit)
- validation Gotcha now matches the research: compile never reads
  prompts, install fails only on a bad Copilot hook payload and warns on
  prompt input names and dropped keys
- instruction fold-in into AGENTS.md/CLAUDE.md stated as conditional on
  dedup and --force-instructions
- hook checklist gains the wrapped-shape Must, drops hardlinks, notes
  why executable is stricter than the research, and states the
  separate Copilot-targeted package route instead of a blanket "don't"
- prompt Must 5 keeps the research's Copilot-only-key exception; adds
  model-slug and 250-char Shoulds; descriptions name skills or agents
- placeholder instruction covers both FILL IN and FILL_IN_ tokens

factory-audit: hardlink FAIL scoped to instructions and prompts
(find_hook_files skips symlinks only), with bats cases; prompt-flow
description rubric names skills or agents.

forge: version-bump, apm-routes and sources references updated for the
primitive route.
