Jordan Ritter 5acbbcd633 feat(showcase/scripts): add validate-parity.ts demo/spec/qa parity validator
Audits each showcase package's manifest-declared demos for matching
spec (tests/e2e/*.spec.ts) and qa/*.md coverage, and enforces a
monotonic demo-count baseline via fail-baseline.json.

Key design:
- PackageIssue tagged union (13 variants) cleanly separates MUST
  errors from warnings; deriveMessage is the single renderer so new
  variants cannot emit mismatched prose.
- ProbeResult tagged union (missing | ok | unreadable) driven by
  statSync + errno inspection, distinguishing ENOENT from EACCES and
  surfacing ENOTDIR as a misconfiguration rather than a silent miss.
- runParityImpl isolates each slug's audit in try/catch; a crash in
  one slug surfaces as a crashed PackageIssue variant and forces
  EXIT_INTERNAL without aborting siblings.
- runParity never throws for content errors. InvalidBaselineError
  covers coerceBaseline failures; unknown errors route to
  EXIT_INTERNAL via formatErrorChain (walks .cause with cycle
  guard + depth cap).
- parseMainArgs rejects unrecognised flags and duplicate --baseline
  with EXIT_INVALID_INPUT (2), mirroring audit.ts parseArgs
  discipline.
- BASELINE_DEMO_COUNT default must match
  fail-baseline.json.baselineDemoCount; enforced by
  __tests__/baseline-sync.test.ts.
- Exit codes: 0 ok, 1 should-warnings-only, 2 invalid-input, 3
  unreadable, 4 internal, 5 must-failure.

Tests cover every PackageIssue variant, every exit code
(in-process + subprocess), per-slug crash isolation, EACCES routing,
ENOTDIR classification, cascade suppression when tests/e2e or qa
dirs are unreadable, and baseline coercion edge cases (leading
zeros, negative, float, hex, non-numeric).

/**
* Sync contract: validate-parity.ts's BASELINE_DEMO_COUNT constant and
* fail-baseline.json's `baselineDemoCount` field are two declarations of
* the same number — the per-package e2e-spec-count floor. The workflow
* .github/workflows/showcase_validate.yml reads the JSON; validate-parity.ts
* uses the TS constant as its default. A divergence means the validator
* and the CI gate disagree silently, so we lock them together here.
*
* Prior to this test the contract was enforced only by a comment ("keep
* in sync"), which is trivially violated without any CI signal. R29-7
* finding #4 / R29-5.
