B89. Search past trails by what you remember.

Where (your choices: CommandBar + canvas search, local rules, go to it in its trail)

• CommandBar (⌘L, ⌘T): a new "In your trails" group, up to four rows.
• Canvas search bar: the same results under an "In your trails" heading, after Search the web, Ask and Private search. Cards on the current trail are left out there, since the search bar already marks them.
• Each row says why it matched, the day and the trail: after “Memex – Encyclopedia” · Tue 3 Nov · Reading list.

What NODE reads (own rules, no AI, nothing leaves the computer)

• Words: titles, sites, addresses, keywords, excerpts, question and note text, replies, group names. All words must match; title matches rank first.
• Times: today, yesterday, this morning, last night, Tuesday, last Tuesday, this week, last week, this month, last month, in October, 3 days ago, 2 weeks ago, a few days ago, recently.
• Order: after X, before X, around X, next to X. NODE finds the pages that match X, then the pages just after or before them in the same trail.
• Kinds: video, song, podcast, question, thread, note, search, image, screenshot.
• A trail: "in Rye breads".
• Words like "the", "page", "site", "saw" are ignored. Pages that stayed in the timeline are found too.

Picking a result

• Switches to its trail and selects its card on the canvas, with a short ring (opacity only; no motion with reduced motion).
• A page that never became a card: shows the canvas and marks its row in the sidebar's timeline.

Code

• New core/recall.js (no platform imports): parseRecall, recallIndex, recall.
• main.js: trail:recall. preload.js: trailRecall.
• renderer/app.js: CommandBar group, goRecall, timeline row marking. renderer/canvas.js: the list rows, showFound, flashCard. styles.css: tokens only.

Not in this PR: the Chromium build (its canvas page has the hook but no data yet).

Tests

• test/recall-demo.js (npm run test:recall, in test:unit): 9 checks, including 6,000 pages in 40 trails indexed and searched in about 30 ms.
• New test/e2e/51-trail-recall.js (13 checks), in both CI e2e lists.
• Locally: test:unit, and e2e 33, 34, 36, 42, 43, 44, 49 and 50 still pass.
