Kjell Tore Guttormsen 494a344700 docs(voyage): S19 — leanness: honest test census + prune 3 redundant prose-pins
Closes devils-advocate audit §Top changes #8 (MINOR×MED). Reports the
behavior-test count separately from the doc-consistency prose-pin count so the
cited total no longer oversells behavior coverage, and removes the clearest
reword-fragile redundancies. Conservative scope (operator-chosen): no genuine
regression guard dropped.

1. Suite census (report separately). lib/util/test-census.mjs +
   tests/lib/test-census.test.mjs walk tests/**/*.test.mjs and bucket top-level
   test() declarations into behavior vs doc-consistency-pins (bucket per file,
   regex PIN_FILE_RE), asserting the two sum to the total so neither can drift
   silently. Split emitted as a t.diagnostic: behavior=601 doc-consistency-pins=69.
   Metric = top-level declarations; node:test's runtime total counts subtests
   too and is therefore >= it.

2. Conservative prune (3 tests, each provably subsumed):
   - "trekexecute.md still parses v1.7 plan schema" — tautological OR-chain;
     real coverage = the plan_version:1.7 template pin + plan-validator /
     plan-schema behavior tests.
   - "CLAUDE.md mentions all six pipeline commands" — hardcoded six-string list
     subsumed by the filesystem-driven "commands table mentions every
     commands/*.md file" structural pin.
   - "CLAUDE.md mentions /trekcontinue command" — same subsumption.
   Each removal leaves an in-place note (why + where coverage lives).

3. doc-consistency.test.mjs header now documents the structural-invariant vs
   prose/existence-pin distinction so new pins land in the right kind.

TDD: census test written failing-first (ERR_MODULE_NOT_FOUND before
lib/util/test-census.mjs existed). Suite 699->698 (696 pass / 2 skip / 0 fail):
-3 prune +2 census. plugin validate passes (1 accepted warning).
