test: V1 gate coverage — writing-style resolver + config + jargon + migration + dormancy

Six new gate-tier test files:

- test/writing-style-resolver.test.ts — asserts Writing Style section
  is injected into tier-≥2 preamble, all 6 rules present, jargon list
  inlined, terse-mode gate condition present, Codex output uses
  \$GSTACK_BIN (not ~/.claude/), tier-1 does NOT get the section,
  migration-prompt block present.

- test/explain-level-config.test.ts — gstack-config set/get round-trip
  for default + terse, unknown-value warns + defaults to default,
  header documents the key, round-trip across set→set→get.

- test/jargon-list.test.ts — shape + ~50 terms + no duplicates
  (case-insensitive) + includes canonical high-signal terms.

- test/v0-dormancy.test.ts — 5D dimension names + archetype names
  forbidden in default-mode tier-≥2 SKILL.md output, except for
  plan-tune and office-hours where they're load-bearing.

- test/readme-throughput.test.ts — script replaces anchor with number
  on happy path, writes PENDING marker when JSON missing, CI gate
  asserts committed README contains no PENDING string.

- test/upgrade-migration-v1.test.ts — fresh run writes pending flag,
  idempotent after user-answered, pre-existing explain_level counts
  as answered.

All 95 V1 test-expect() calls pass. Full suite: 0 failures.

+ * V0 dormancy — negative tests.
+ *
+ * V1 keeps V0's psychographic machinery (5D dimensions + 8 archetypes + signal map)
+ * in code but explicitly does not surface it in default-mode skill output. This test
+ * enforces the maintenance boundary: if these strings ever appear in a generated
+ * tier-≥2 SKILL.md's normal (default-mode) content, V0 machinery has leaked.
+ *
+ * Exceptions (explicitly allowed): SKILL.md files for skills that legitimately discuss
+ * V0 machinery:
+ *   - plan-tune/ — the conversational inspection skill for /plan-tune
+ *   - office-hours/ — sets the declared profile
+ * For these, V0 vocabulary is load-bearing and must appear.
+ *
+ * All other tier-≥2 skills: 5D dim names + archetype names must NOT appear.
