Mark 9e45d333cc test(02-01): RED — pin meta.json urls[] schema + dedup/filter + empty-tracker (D-P2-02 + F2) ...

Plan 02-01 Task 2 RED gate. Five failing tests pin D-P2-02 (meta.json
url→urls migration) and the F2 plan-checker-iter-1 resolution (empty-
tracker → urls:[], no sentinel fallback) ahead of Plan 02-03.

Tests:
  1. SessionMetadata interface in src/shared/types.ts has 'urls: string[]'
     and no 'url:' field. Source-text scan (typecheck disabled in
     vitest.config.ts so tsc-failure pin would be a no-op).
  2. createArchive emits meta.json with Array urls and no url field.
  3. meta.urls deduplicates repeated URLs (first-seen-first order).
  4. meta.urls filters chrome:// + about:; includes chrome-extension://.
  5. Empty tracker → meta.urls === [] (NOT undefined/null/[origin]).

RED evidence (vitest 4.1.6 against current HEAD):

  × Test 1: SessionMetadata interface body does not contain a
    'urls: string[]' field (and still contains 'url:').
  × Test 2: meta.urls is not an Array. Got: undefined.
  × Tests 3+4+5: src/background/tab-url-tracker.ts does not exist —
    Plan 02-03 GREEN gate. Each expect.fail emits the precise
    contract for the GREEN flip (export name getTabUrlsSeen(),
    dedup Set semantics, first-seen-first order, URL filter spec,
    empty-array empty-tracker resolution).

Module seam (Plan 02-03 implements):
  src/background/tab-url-tracker.ts
    export function getTabUrlsSeen(): string[]
  Fed by chrome.tabs.onUpdated + chrome.tabs.onActivated (per DEC-011
  Amendment 1 'tabs' permission grant).

Baseline: 155 GREEN preserved (no regressions); this plan now has 8
NEW RED tests total (Task 1: 3 + Task 2: 5).
