Honor HTTP-date Retry-After values in OtlpExporter

[fubhy]

Summary

• add a regression test for HTTP-date Retry-After values
• resolve HTTP-date delays against the configured Effect clock
• preserve numeric delay-seconds and the existing fallback behavior

Verification

pnpm test --run packages/effect/test/unstable/observability/OtlpExporterRetryAfterDate.test.ts packages/effect/test/unstable/observability/OtlpExporter.test.ts
pnpm --filter effect check
pnpm dprint check packages/effect/src/unstable/observability/OtlpExporter.ts packages/effect/test/unstable/observability/OtlpExporterRetryAfterDate.test.ts
pnpm oxlint -f unix packages/effect/src/unstable/observability/OtlpExporter.ts packages/effect/test/unstable/observability/OtlpExporterRetryAfterDate.test.ts

Closes EFF-303

• Reproduction test for HTTP-date Retry-After parsing: adds OtlpExporterRetryAfterDate.test.ts that reproduces the bug where OtlpExporter ignores HTTP-date Retry-After values (RFC 7231), falling through to the 5-second default. The test correctly fails with the current code and would pass once the header is parsed as a date.

Can you please merge this test file into the main one?

Reviewed changes

• Extracted retryAfterDelay function that resolves Retry-After headers against the Effect clock, handling numeric seconds, HTTP-date values (RFC 7231), missing headers, and unparseable strings with the appropriate fallbacks
• Made policy clock-aware by accepting a Clock parameter so that HTTP-date delays compute a relative duration rather than a static one
• Added HTTP-date retry test that follows the existing three-phase pattern — verifies the initial 429 is counted, no premature retry at 5s, and the retry occurs after the full 60s delay
• Merged the reproduction test into the main OtlpExporter.test.ts file

Instead of threading through the clock, you can access using the reference.

✅ No new issues found.

Reviewed changes

• Switched retryAfterDelay to read Clock from environment rather than threading it as a parameter — policy is back to a module-level const, and all branches return Effect.succeed(...). The HTTP-date branch uses Effect.map(Clock, ...) to compute the delay relative to the runtime clock.
