The Go API returns _id as a JSON string (due to the `json:",string"` tag
on Item.Id), but the frontend compared it with === against numbers from
parseInt(). String "5" === number 5 is always false in JS, so toggleStar,
mark-as-read, and keyboard shortcuts silently did nothing.

Fix:
- Coerce _id to Number() when items are loaded from the API
- Use Number() coercion in all store.items.find() comparisons as defense
- Revert the CSS touch-target changes (the issue was never about size)
- Add a regression test with string _id to prevent reintroduction

Add AGENTS.md with TDD workflow and check-in guidance for agents.

Fix star buttons being nearly impossible to tap on mobile by:
- Adding min-width/min-height of 44px for proper touch targets
- Adding flex-shrink: 0 so the button isn't squeezed by long titles
- Overriding generic button styles (height, text-transform, font-weight)
  that bled into the star button

The float:right "text" button inside .dateline was causing .item-description
content to wrap around it when .feed-item gained overflow:hidden. Removing
the button fixes the squished text regression. The backend scrape endpoint
and scrapeItem() handler remain intact for potential future use.

Test files use Node built-ins (fs, path) which aren't available to the
browser-targeted tsconfig. Excluding *.test.ts from tsc is the standard
Vite/Vitest pattern — vitest handles test type-checking separately.

Also rebuilds web/dist/v3/ to include the CSS overflow fixes.

The previous fix (overflow-x:hidden on .main-content and .item-description)
was insufficient because mobile Safari ignores overflow-x:hidden on elements
with overflow-y:auto. The real fix is item-level containment:

- .feed-item: add overflow:hidden to create a BFC so no child content can
  push the viewport wider, even during async image load reflows
- .item-title: add min-width:0 (fixes flex min-width:auto bug that prevents
  shrinking below content width) and overflow-wrap:break-word for long titles

RSS feeds can contain tables, iframes, and other elements with explicit
widths that overflow the viewport on mobile. Added overflow-x: hidden to
.item-description and .main-content, and extended max-width: 100% to
cover table and iframe elements inside item descriptions.

Includes TDD tests verifying the CSS containment rules.

Removed text-decoration: underline from .item-title:hover in the source
CSS and rebuilt the frontend assets so the compiled dist reflects the change.
