Bump react and react-dom 19.1.2 -> 19.2.7 and @types/react and
@types/react-dom from v18 to v19. Keeps babel-plugin-react-compiler,
which is a separate build-time tool, not part of the React 19 runtime.
The @types v19 upgrade surfaced 21 type-only errors, all fixed without
runtime behavior changes:
- useRef<T>() now requires an explicit argument: pass undefined
- DOM element refs are RefObject<T | null>: widen PostFormFields and
AdvancedSettings ref prop types accordingly
- retype reply-modal onInput handler to FormEvent + currentTarget
- add a null guard for the boards-bar search input
- update test mocks for stricter cloneElement/forwardRef typings
Verified: type-check, lint, 1051 tests, and build pass; react-doctor
score unchanged at 54; browser smoke across Chromium/Firefox/WebKit
plus mobile viewport clean.
* fix(comment-content): render reason text as comment content
* fix(post-form): use native browser styling for flash tag select
Exclude the flash tag dropdown from themed post-form select styling so it
renders with the browser's default select appearance, matching the flag selector.
* fix(p2p-stats): show peer flags for DNS6 relay hostnames
Extract embedded IPv6 addresses from dns6 multiaddrs so geo lookup and country flags work for relay peers that publish IPv6 via DNS hostnames.
* fix(flags): hide geolocation-only selectors on /int/ and /sp/
Country-only boards auto-publish geographic location flags without
showing a flag dropdown, matching existing /bant/ behavior.
* fix(embed): restore youtube thumbnails and file-row labels
Restore thumbnail-first previews for YouTube embeds in post media and markdown hover.
Desktop posts show File with the thumbnail image URL and a youtube video type label.
* fix(embed): address youtube thumbnail review feedback
Translate the youtube video label, handle mobile/music YouTube hosts as standard YouTube URLs, keep affected mocks current, and cap default Vitest workers to reduce local CPU spikes.
Add pw-throttle.sh and a verification playbook so agents can stress-test UI
on throttled Chromium sessions before claiming perf-sensitive changes feel fast.
* fix(p2p stats): improve own-IP geolocation and world map accuracy
Resolve the user's public endpoint when libp2p only advertises private listen addresses, look up an accurate country flag for "Your IP", snap peer markers to country centroids, and add leeching seeder link plus panel layout tweaks.
* fix(p2p stats): skip caching own-IP lookups cancelled by abort
When the P2P stats panel unmounts mid-request, its AbortSignal cancels
the in-flight fetchOwnPublicEndpoint / fetchOwnIpCountryCode calls. Those
empty results were still cached for 30-60s, so reopening the panel within
that window showed "Your IP" as unavailable or without a country flag even
though nothing had actually failed. Skip caching when the signal aborted so
a later open retries. Addresses Cursor Bugbot finding.
