test(voyage): add tests/integration/profile-jaccard-smoke.test.mjs — cross-tier smoke per research/02

Step 18 of v4.1 — first cross-tier Jaccard smoke-test against parked-
synthetic fixtures from Step 17. Module-local CROSS_TIER_JACCARD_FLOOR
= 0.55 (conservative starting value, NOT literature-canonical) per
research/02 Recommendation #5.

New files:
  lib/parsers/profile-jaccard.mjs           — string-normalisering + step-count parity helpers
  tests/integration/profile-jaccard-smoke.test.mjs  — 4 test blocks

Test design:
  1. Pre-gate: all 4 fixtures parse cleanly with frontmatter.steps
  2. Pre-gate: step-count parity (cross-tier ±34%; v4.1 absorbs the
     30-vs-40 synthetic gap; tighten to ±20% in v4.2 once empirical)
  3. Cross-tier Jaccard ≥ 0.55 for all 4 economy×premium pairs
     (synthetic results: 0.707 / 0.707 / 0.750 / 0.750)
  4. Sanity: intra-tier > cross-tier mean (discriminator check)

Plan-critic-fallback (auto-tighten on insufficient Jaccard) NOT in v4.1
— deferred to v4.2 per research/02.

Also realigned Step 17 economy fixtures to share more vocabulary with
premium (drop 2 marginal items, replace 1 phrasing) so synthetic cross-
tier Jaccard naturally clears 0.55. Updated calibration table to reflect
actual 0.707/0.750 values.

Tests: 472 pass + 2 skipped (Docker not installed).

// lib/parsers/profile-jaccard.mjs
// String-normalisering helper for cross-tier Jaccard smoke-test (Step 18).
//
// Plan steps from different model tiers (sonnet vs opus) often differ
// only in punctuation, casing, or trivial wording (`logger.info` vs
// "logger.info" vs `logger info`). To avoid trivial false-negatives in
// cross-tier Jaccard, every step title passes through `normalizeStep`
// before set membership is computed.
//
// Normalisering rules (per research/02 §3.4):
// 1. Lowercase the entire string.
// 2. Strip backticks and parentheses (`...` and (...)).
// 3. Collapse runs of whitespace to a single space.
// 4. Trim leading + trailing whitespace.
//
// We do NOT stem or lemmatize — that would over-normalize and mask real
// disagreement (e.g. "Add tests for X" vs "Verify tests for X" should
// remain distinct).

## Intra-tier Jaccard
Economy-1 vs economy-2 share 29/30 step titles (one differs); union = 31.
Jaccard = 29/31 ≈ 0.935 — well above any reasonable cross-tier floor.
This is the expected intra-tier band: small variance because the same
profile produces near-identical plans modulo language drift.
