[codex] Structure release output failures

[juliusmarminge]

Summary

• wrap GITHUB_OUTPUT configuration and append failures with structured Schema errors that preserve their exact causes
• retain output paths for failed appends without retaining serialized output contents
• distinguish git stdout and stderr read failures and constrain counts and lengths to non-negative integers

Validation

• vp test scripts/resolve-nightly-release.test.ts scripts/resolve-previous-release-tag.test.ts
• vp check (passes with existing repository warnings)
• vp run typecheck

Note

Low Risk
Changes are limited to CI release scripts and error typing; no runtime app, auth, or data-path behavior changes.

Overview
Release helper scripts now surface GITHUB_OUTPUT failures as tagged Schema errors instead of raw Effect failures, while keeping the original cause (and outputPath on append failures) without leaking serialized output into error messages.

resolve-nightly-release exports writeNightlyReleaseOutput and adds NightlyReleaseGitHubOutputConfigError / NightlyReleaseGitHubOutputAppendError around config lookup and file append.

resolve-previous-release-tag does the same for writePreviousReleaseTagOutput with PreviousReleaseTagGitHubOutput* errors. listGitTags maps stdout vs stderr read failures to read-stdout / read-stderr (replacing a single communicate), and constrains argument counts and stream lengths with non-negative integers.

Tests assert cause preservation and that user-facing messages do not echo underlying platform/config text.

Note

Add structured tagged errors to release output failure paths in nightly and previous-release-tag scripts

• Exports writeNightlyReleaseOutput and writePreviousReleaseTagOutput (previously internal writeOutput) with structured tagged errors for GITHUB_OUTPUT config resolution failures and file append failures, each preserving the underlying cause.
• Adds NightlyReleaseGitHubOutputConfigError, NightlyReleaseGitHubOutputAppendError, PreviousReleaseTagGitHubOutputConfigError, and PreviousReleaseTagGitHubOutputAppendError error classes.
• Expands ReleaseTagListProcessError operation literals to distinguish read-stdout vs read-stderr failures in listGitTags.
• Adds tests verifying error types, preserved causes, and output paths for both config and append failure scenarios.

Approvability

Verdict: Approved

Changes are limited to CI/CD release scripts, adding structured error classes for better error reporting when GitHub Actions output operations fail. No production code is affected, and comprehensive tests cover the new error handling paths.
