The capabilities probe used a fixed 5s timeout, so a readiness budget
shorter than that could be overrun by one stalled request. Pass the
remaining deadline down instead.
stop() also resolved after the SIGKILL wait even when the child had not
exited, letting a restart race a process still holding the port. Throw
in that case, and keep a failed shutdown from masking the readiness
error at startup.
Addresses CodeRabbit review feedback on the Anime Browser:
- reject repository package/apk names that are not plain identifiers, and
verify the install target resolves inside the extensions directory
- count mpv's %n% option escape in UTF-8 bytes, and escape backslashes in
header values so a trailing one cannot eat the list separator
- key the bridge extension-id cache by APK content, so an in-place upgrade
re-uploads instead of running the previous build
- bound every bridge, release-listing, and download request with a timeout
- enforce the APK size limit while streaming rather than after buffering
- read APK bytes on demand instead of holding a base64 copy per extension
for the lifetime of the browser
- serialize preference mutations and write the file atomically
- handle the sidecar spawn error event, and wait for the child to exit in
stop() before returning
- report a failed Anime Browser bootstrap instead of showing the starting
banner forever
- keep the preferences panel's save confirmation and in-flight multi-select
edits by re-rendering only on a structural schema change
