test(asupersync): add cancellation, parity, and E2E acceptance tests
- Add 7 cancellation integration tests (ShutdownSignal, transaction rollback) - Add 7 HTTP behavior parity tests (redirect, proxy, keep-alive, DNS, TLS) - Add 9 E2E runtime acceptance tests (lifecycle, cancel+resume, tracing, HTTP pipeline) - Total: 1190 tests, all passing Phases 4-5 of asupersync migration.

//! HTTP behavior parity tests: verify asupersync h1 matches reqwest semantics
|
||||
//! that `lore` depends on.
|
||||
//!
|
||||
//! These tests confirm six critical behaviors:
|
||||
//! 1. Auto redirect: 301 -> follows Location header
|
||||
//! 2. Proxy: HTTP_PROXY not supported (documented)
|
||||
//! 3. Connection keep-alive: sequential requests reuse connections
|
||||
//! 4. System DNS: hostname resolution works
|
||||
//! 5. Content-Length on POST: header is auto-added
|
||||
//! 6. TLS cert validation: invalid certs are rejected
