Fix reset display and release recovery semantics

[cbusillo]

Summary

• stop relabeling Google/Antigravity model-capacity windows as weekly windows, so short model reset windows no longer appear as misleading weekly resets
• fill missing Claude OAuth reset timestamps from the local Claude Code statusline cache without overwriting OAuth-provided values
• accept Unix timestamp reset values in the shared Context Panel JSON date decoder
• normalize Release workflow concurrency so tag-triggered and Ship-triggered runs for the same version serialize together
• allow cancel-only App Store review recovery without requiring build metadata or release notes

Validation

• swift test --filter 'googleAntigravityMainSummariesUseOnlyGeminiAvailability|claudeOAuthConnectorRefreshesUsageWindows|claudeOAuthConnectorAcceptsEpochResetTimes|claudeOAuthConnectorFillsMissingResetTimesFromStatuslineHints|usageLimitSeparatesWindowAndModelLabels'\n- swift test\n- python3 -m unittest Tests/ScriptsTests/test_submit_app_store_review.py\n- actionlint .github/workflows/release.yml .github/workflows/submit-app-store-review.yml\n- git diff --check\n- scripts/commit-gate.sh\n- scripts/context-panel-runtime-baseline.sh install --launch\n- installed refresh agent --refresh-once produced a fresh snapshot with Anthropic reset timestamps present\n\n## Review\n- Claude/Gemini review of reset-display commit: no blockers\n- Fresh Claude/Gemini review of current PR head is running after the release workflow follow-up\n- Detached auto-review findings f1/f2 from auto-review-715f775a are addressed by the release concurrency and cancel-only recovery changes\n\n## Runtime note\nThe fixed app/runtime behavior has already been installed to /Applications/Context Panel.app through the runtime install gate. The second commit only changes release workflow/script behavior.
