chore: remove unreliable octet stream benchmarks

[dinwwwh]

Removes the `octet stream` benchmarks from the rpc and openapi link + handler suites. They kept producing false CodSpeed regressions and improvements on PRs that don't touch streaming, so CodSpeed reports become trustworthy again.

Why

• On `main`, with no code changes, the rpc octet stream result flips between two values (~640 µs and ~728 µs).
• Across CodSpeed comments on PRs fix(rpc): reject non-Blob values in serialized blobs #2060–fix(openapi): fix regex pattern for numeric path validation #2186, it was flagged 36 times, always at a near-constant ±12–14%. One of those was chore: list every package in the jsdom vitest project in CLAUDE.md #2157, a `CLAUDE.md`-only change. The openapi octet stream bench was falsely flagged twice (+18.3%, −11.3%).
• The flips appear to follow the runner CPU (GitHub alternates between AMD EPYC 7763 and 9V74), and most flagged comments carry "Different runtime environments detected".
• Locally, the measured call never waits on a timer or I/O and does the same async work every time, so the variance comes from the CI environment rather than from oRPC code.

Testing

• `buffered` and `event stream` benches in both files still run.
• Lint and type-check are clean for the touched files.

Important

Dropping the ReadableStream branch from the shared drainBody helper also changes the static-file benchmarks, which is outside this PR's stated scope and should be addressed before merge.

Reviewed changes

• Removed the two octet stream benches — deleted bench('octet stream', ...) from benches/rpc-link-handler.bench.ts and benches/openapi-link-handler.bench.ts plus their now-unused imports; buffered and event stream remain.
• Pruned shared payload helpers — removed asReadableStream, splitBytes, BYTES_1KB/10KB/100KB/5MB, and the unused SIZE_1KB/10KB/100KB; SIZE_5MB is retained for FILE_BYTES.
• Reduced drainBody — kept only the isAsyncIteratorObject branch; the ReadableStream draining path was removed along with the octet benches.

No dangling references to the removed helpers remain in benches/.

✅ No new issues found.

The delta since the last review (2456e6a) restores the ReadableStream draining branch in drainBody, which resolves the static-file regression flagged previously. The removal cleanup itself is clean and free of dangling references.

Reviewed changes

• Restored the ReadableStream drain path in drainBody — benches/__shared__/payloads.ts:85-98 again consumes ReadableStream response bodies, so benches/static-file-handler.bench.ts once more measures the full serve path and releases the reader. This was the sole concern from the prior review and is now addressed.
