fix(kyberforge): align primitive-author and factory-audit rule tiers

Second clean-context audit found author Must/Should and audit FAIL/SUGGESTION
tiers drifting apart, and author Musts the audit never checked.

- factory-audit: FAIL on absolute or bare relative hook script paths, an
  applyTo present but empty, and unbalanced braces/brackets in applyTo;
  judgment steps for dependency stem collisions, helper .json in hook dirs,
  unresolvable instruction links, prompt model slugs and second-person
  bodies; an unmatched glob drops to SUGGESTION; deliberate tier deviations
  recorded in hook-flow.md; validate.sh --help lists the three new modes;
  DescriptionOpener message no longer prescribes "Use when".
- primitive-author: deprecated routing, extra prompt keys and the prompt
  description contract become Shoulds; hook Musts gain "contributes an
  entry", no bare relative paths, and executable-when-run-directly;
  prompt Must 1 covers hardlinks; Vale prose FAILs resolved at close.
- forge: say "hook, instruction or prompt" rather than "apm primitive".

 `vale-wrap.sh` applies the bundled `Kyberforge` style. Every alert is a FAIL under `### Prose`, cited by rule ID; do not re-derive it by judgment. `0 files` scanned means NOT RUN, not clean — say so and judge prose by reading.

 **scope** — an instruction applies when files matching `applyTo` are touched; with no `applyTo` it loads into every session of every repo that installs the package.
 
 - FAIL: an always-on file whose content is a rule for this repo alone — it belongs in `AGENTS.md`, which is the repo's single always-on source, not in a package that ships it to every consumer.
-- FAIL: an `applyTo` glob that matches no tracked file in any repo the package plausibly targets, so the rule never loads.
+- FAIL: the stem matches an instruction an installed dependency ships — both deploy to `.claude/rules/<stem>.md`, and one silently overwrites the other.
+- SUGGESTION: an `applyTo` glob that matches no tracked file here. It is legitimate for files the package's consumers have and this repo does not, so name the mismatch rather than failing it.
 - SUGGESTION: an always-on file whose content is really file-type specific — narrow it with `applyTo`.
 - SUGGESTION: a glob much broader than the content (`**` for a rule about Python).
 
 **description**
 
 - SUGGESTION: the description does not say what the rule covers, or contradicts the body. Any rationale Claude readers need belongs in the body, because Claude drops the description.
+- SUGGESTION: a relative markdown link that does not resolve from the source file — apm rewrites links on deploy, and a broken one stays broken on every target.
