Kenneth 4b824c66ce feat(tfl): add FeedItemRenderer for TfL alerts (#73)
* feat(tfl): add FeedItemRenderer for TfL alerts

Implement renderTflAlert using JRX and @aelis/components.
Upgrade @nym.sh/jrx to 0.2.0 for null child support.

* fix(tfl): add jsxImportSource pragma for CI

The CI test runner doesn't use per-package tsconfig.json,
so the pragma is needed alongside the tsconfig setting.

* fix(ci): run tests per-package via bun run test

Use 'bun run test' (which runs 'bun run --filter * test')
instead of 'bun test' so each package runs tests from its
own directory. Add jsxImportSource pragma to renderer files
since consumers without a JRX tsconfig also import them.

* fix(tfl): handle near-1km boundary in formatDistance

Values like 0.9999km rounded to 1000m and displayed as
'1000m away'. Now converts to meters first and switches
to km format when rounded meters >= 1000.
