Measure TypeScript transform latency

[noise64]

• resolves https://linear.app/golem-cloud/issue/GOL-417/measure-and-mitigate-uninterruptible-typescript-transform-latency
• adds a manual, report-validated latency suite for inline, entry, ESM, prepared ESM, CommonJS, and direct TypeScript transformation across P2/P3 and strip/transform modes
• records the requested 4/16/64 KiB historical profiles; generated declarations and suffixes make the largest actual inputs 65,602–65,637 bytes
• scopes the accepted 25 ms native-transform bound to the recorded three-sample macOS arm64 profiles; all direct-API maxima are at most 20.77 ms
• shows that prepared ESM reproduces nearly all of the roughly 11-second strip-mode ESM delay in the recorded profiles, leaving current phase profiling and mitigation with GOL-347 / PR Profile TypeScript execution and reduce module-resolution probes (GOL-347, GOL-350) #134
• clarifies that timeout deadlines and cancellation timers are armed before synchronous transformation, while cancellation is delivered only after the outer runtime regains control
• preserves the original workload capture commit, report input hashes, component identities, and timing data instead of relabeling historical measurements as current
• makes run.sh --check validate report contracts and the complete P2/P3 matrix, while run.sh --check-current explicitly detects whether a new measurement capture is required
• integrates current main normally and changes no production runtime behavior
