Deciding what should be an lp.assert, vs an std.debug.assert, vs a debug-only
assert is a little arbitrary.
debug-only asserts, guarded with an `if (comptime IS_DEBUG)` obviously avoid the
check in release and thus have a performance advantage. We also use them at
library boundaries. If libcurl says it will always emit a header line with a
trailing \r\n, is that really a check we need to do in production? I don't think
so. First, that code path is checked _a lot_ in debug. Second, it feels a bit
like we're testing libcurl (in production!)..why? A debug-only assertion should
be good enough to catch any changes in libcurl.
Zigdom broke request interception. It isn't zigdom specifically, but in zigdom
we properly block the parser when executing a normal (not async, not defer)
script. This does not work well with request interception, because an
intercepted request isn't blocked on HTTP data, it's blocked on a message from
CDP. Generally, neither our Page nor ScriptManager are CDP-aware. And, even if
they were, it would be hard to break out of our parsing and return control to
the CDP server.
To fix this, we expand on the HTTP Client's basic awareness of CDP (via its
extra_socket field). The HTTP client is now able to block until an intercepted
request is continued/aborted/fulfilled. it does this by being able to ask the
CDP client to read/process data.
This does not yet work for intercepted authentication requests.
