fix(linkedin): scroll the real container so profile-read sees Experience and Education (#417)

[Agnik47]

Closes #417.

Cause

profile-read calls page.autoScroll(), which is window.scrollTo (src/browser/dom-helpers.ts:133). LinkedIn's current profile UI scrolls inside main#workspace, so the window scroller never moves, the lazy loaders for Experience and Education never fire, and the command exits successfully with both fields empty — while profile-experience returns the same profile's entries.

The reporter's read-only inspection matches: window.scrollY stayed 0, and scrolling main#workspace brought the headings into the DOM.

Fix

plugins/linkedin/shared.js gains buildSectionScrollScript / scrollToSections, following the #workspace pattern already used by post-comments.js:

• Scroll the element that actually scrolls — main#workspace, else the nearest scrollable ancestor of main, else the window.
• Stop as soon as every requested heading is in the DOM.
• One atEnd round is not the end. LinkedIn lazy-loads on reaching the bottom, so the container grows and the next round has further to travel; the helper requires two consecutive end rounds with no newly found section.
• Never throw. A layout the helper cannot scroll is not a command failure, only a reason the extraction below it may see fewer sections.

profile-read.js keeps page.autoScroll() ahead of the new call so older window-scrolling layouts are unaffected.

Contract

• profile-read loads About, Experience, Education, and Featured on a main#workspace layout.
• Window-scrolling layouts keep their existing behavior.
• Output columns are unchanged.

Tests

plugins/linkedin/test/shared-scroll.test.js (new), driving the generated script through JSDOM:

• main#workspace is scrolled and the window scroller is not touched.
• Requested headings are reported once present.
• A layout with no inner container falls back to window.scrollTo.
• atEnd is reported at the bottom of the container.
• The round loop stops on found sections, stops on a stable end, keeps going past an atEnd round that lazy-loaded a new section, respects the round budget, and returns instead of throwing when evaluate fails.

plugins/linkedin/test/profile-read.test.js: a main#workspace fixture where the sections appear only on the third round now resolves with non-empty experience and education, asserting the scroll rounds run before extraction and that autoScroll is still called.

npx vitest run --project plugin plugins/linkedin — 28 files, 260 tests passed.
node scripts/check-plugin-pr-scope.mjs upstream/main HEAD — exit 0. npm run check:plugin-parity — OK.

Scope

One adapter and one shared helper in the LinkedIn plugin. autoScrollJs is left alone deliberately: changing the generic scroller would affect every adapter in the repo, and this issue is scoped to the profile layout.
