* Update preact to 10.29.8
Also moves TypeScript to 5.9, which preact 10.29 typings require, and the
compat and testing library pins that go with it. Type checking resolves
JSX from preact via the automatic runtime; the bundle keeps the classic
transform so babel still strips test ids.
* Move babel to the automatic JSX runtime and refresh frontend notes
Leaving babel on the classic h pragma while tsconfig used the automatic
runtime meant a tsx file without an h import would type-check and lint
clean, then throw at runtime, since eslint-config-preact disables
react/react-in-jsx-scope and no-undef is off.
* Address review findings on the preact upgrade
Forward the textarea ref with useImperativeHandle so it clears on unmount
and lands during commit rather than after paint. Pair typescript-eslint
with the TypeScript it now has to parse. Use the preact namespace types
rather than the deprecated JSX aliases, and drop the redundant type
re-declarations the element-specific interfaces already provide.
* Drive the focus tests through real DOM focus and blur
Dispatching a synthetic focusin hard-coded preact/compat's internal
alias for onFocus. Calling focus() and blur() exercises the sequence a
browser produces and stays correct if that mapping changes.
* Raise the two bundle limits the preact upgrade pushes past
CI measures remark.mjs at 78024 bytes against a limit size-limit reads as
78000, so it failed by 24. last-comments.mjs had 36 bytes of headroom and
would have tripped on the next change.
* Regenerate the lockfile after the rebase
The rebase resolution left it missing the @typescript-eslint entries, so
every CI job failed at pnpm install --frozen-lockfile.
