Generated names now use escaped double-quoted literals, but callback diagnostic names and asm.js export rewriting still assumed the earlier quoting. Escape callback labels and decode core export literals before mangling them so async MoonBit exports and the asm.js flavorful component instantiate correctly. Update enum, resource-disposal, and import assertions to accept either quote style while preserving their behavioral checks.

Cache Chrome and Firefox installations for browser examples, with separate keys by example, OS, architecture, lockfile, and installer. This avoids repeated downloads and extraction on cache hits. The native-messaging job in the linked run lost its hosted runner during Firefox installation; its log is unavailable.

Add four commented WAT fixtures for numeric and escaped core export names, plus suspending and non-suspending JSPI callbacks whose names contain quotes, backslashes, and a newline. Each fixture explains the behavior it exercises, and the regression tests transpile and execute those fixtures.

Keep the public HTTPS smoke check focused on verified TLS transport: a valid HTTP error response such as 503 must not fail because the remote service is unavailable. Add a local 503 response case using the existing HTTPS component fixture, with exact status and body assertions, verified handshake checks, and resource cleanup checks. Certificate and hostname rejection checks remain strict.

Addresses failures from the extended job, the Node 22 transpile job, and repeated browser setup in the native-messaging job.
