Summary

Move Oscope onto the canonical merged SDK, Durable confirmed-ticket driver and
exporter preparation stack. This closes the dependency prerequisite for the
application integration in #180 without enabling overlap or changing capture
defaults.

• SDK 38278ab4, driver 312812f0, exporter e5190e85.
• Update exact dependency/runtime-declaration test expectations.
• Preserve codec, crypto, data.json and separate historical qualification pins.
• Add changelog and compact qualification notes; no application source changes.

Validation

Stock Jolt 0.8.23 / mandatory Chez 10.4.1; native checks select chDB 26.9.0:

• Final canonical pins: 44 tests / 546 assertions, dependency resolution,
  runtime declarations and export options; zero failures/errors.
• Pre-merge candidate: full embedded 32/705, real embedded capture 1/18,
  standalone socket ingestion 1/45, both with checked fresh-reader receipts.
  Real codec/stream calls were observed. Those native runs selected exporter
  PR head a12c6f4; its complete Git tree and final merge e5190e85 are identical
  (a708569fe6b5574f50aa2eb696da28d7bef8aefa), verified through GitHub.
  They are not retrospectively labeled final-coordinate native runs.
• Dependency tests retain wrong-coordinate/downgrade controls, and historical
  producer/native-profile declarations are intentionally unchanged.
• Independent Claude read-only review of the final four-file pin/changelog
  diff found no blockers; Codex owns the verification above.

No new throughput, S3 performance, full Samizdat qualification or preparation
enablement claim. Mixed signals and startup/shutdown ownership must be preserved
when #180 adds the explicit opt-in.
