Prepare Server 2.3.0 and Helm chart 0.1.79

[rmcdaniel]

Summary

Publish the opt-in storage-pressure admission feature and large-completion MySQL attribution fix merged in #132. The feature adds an optional operator-owned normal/draining/fenced observation without changing default behavior or the worker protocol floor.

The source release manifest is the version authority; existing generated Compose/Helm/package consumers are updated with scripts/ci/sync-source-release.mjs. No dependency upgrade or production configuration change is included.

Validation

• Source consumers are synchronized and git diff --check passes.
• The complete source-release suite passed in the public Repository contracts check. The initial local run passed two tests and could not run the PHP-dependent third test because this host has no PHP binary.
• Required feature, MySQL topology, Helm, release, and performance-smoke checks must pass before merge.
• The native bounded MySQL proof is on Add storage-pressure admission before capacity exhaustion #132. Published Server/SDK and actual deployment qualification remain in Add storage-pressure admission before backing storage is exhausted #131 before admission enablement.

This release addresses #133. Close that defect only after the exact image is published and verified. #134 is a separately tracked malformed worker-input validation gap, not part of this release.

Merged after all public checks passed, including the full feature suite, MySQL HTTP topology, MySQL/PostgreSQL predecessor-successor checks, Helm install, and performance smoke. The immutable 2.3.0 tag points to c8c973d; image and chart publication is running.

PHP SDK 2.0.7, Python SDK 2.0.3 and Rust SDK 2.0.2 are now published and verified through their owning release records. #131 remains open for the combined published qualification, and #133 remains open until image publication/verification completes. No production admission configuration or Cloud deployment changed.
