feat(proxy): gzip buffered responses for clients that accept it (#44052)
* feat(proxy): gzip buffered responses for clients that accept it

Large JSON reads like /user/daily/activity/aggregated shipped tens of MB
uncompressed. Compress single-message bodies of 500B or more when the
client's Accept-Encoding allows gzip (q-values and the wildcard honored).
Streamed and etagged responses pass through untouched, every negotiable
response carries Vary: Accept-Encoding, and bodies of 1MB or more are
compressed in a worker thread

* fix(proxy): skip partial and no-transform responses in gzip and always release the held start

The gzip gate now also skips 206 Partial Content and Cache-Control: no-transform,
since compressing either breaks byte ranges or ignores an explicit ban on transforms.
A response start without a headers key no longer raises, and a start the app never
follows with a body message is forwarded when the app returns instead of being dropped.
