GOL-420: capture correlated WASI HTTP lifecycle traces

[noise64]

• resolves https://linear.app/golem-cloud/issue/GOL-420
• adds fixed-size, lock-free P2/P3 outgoing HTTP lifecycle journals to the runtime test host
• folds server connection ownership, response byte accounting, terminal/error/drop boundaries, and overlap diagnostics into the same test-only trace
• records client and server observations independently without injecting private correlation headers or mutating guest-visible requests
• attaches decoded journals and existing Wasmtime HTTP warnings only after an invocation fails
• preserves stock and Golem Wasmtime dispatch semantics, including P2 body-completion ownership
• remains diagnostic-only: no retry, serialization, timeout inflation, localhost branch, or production behavior change is included
• keeps GOL-405 separate unless evidence identifies the same behavioral owner

Validation covers 21 focused lifecycle cases in both P2 and P3, guest-header preservation, socket ownership and byte accounting, formatting, and the inherited P3 stream-lifecycle regressions at exact SHA be7547cfcca106f61868e589661fdd1ed9b73ba7.
