Add sync-reminder workflow; bump to 0.2.3

[avifenesh]

Added

• A sync reminder CI workflow that opens (or updates) a codex-sync-labeled issue when a merge to main touches the crate sources (src/**, Cargo.toml, gnome-shell-extension/**), so the change can be propagated into the codex-desktop-linux embedded copy — re-applying its codex naming (codex-* / CODEX_COMPUTER_USE_*, com.openai.Codex.* DBus, identity.rs, chrome-extension host). Merge, do not overwrite.

Changed

• Bump to 0.2.3 to establish version-enumeration parity with the codex-desktop-linux embedded copy (0.2.3-linux-alpha1). The two crates are kept on the same enumeration on purpose: a mismatch signals a pending sync between them.

Counterpart PR (embedded copy receiving the 0.2.2 feature sync): ilysenko/codex-desktop-linux#274

Code Review

This pull request bumps the version of the computer-use-linux crate to 0.2.3 and updates the CHANGELOG.md to include details about a new sync reminder CI workflow. Feedback indicates that the actual workflow configuration file mentioned in the changelog is missing from the changes and suggests including the specific label name in the documentation for clarity.

The pull request title and this changelog entry indicate the addition of a sync reminder CI workflow. However, the actual workflow configuration file (e.g., .github/workflows/sync-reminder.yml) is missing from the changes in this pull request. Please ensure the workflow implementation is included.

Additionally, for better documentation, consider specifying the label name (codex-sync) mentioned in the PR description within this entry.

Re @gemini-code-assist review:

• Workflow file is present — .github/workflows/sync-reminder.yml is included in this PR (gh pr diff --name-only lists it); it isn't missing. The Gemini diff view may have skipped the .github/ path.
• Label name — good call; the changelog entry now names both the file and the codex-sync label (e09d7dc).

Also fixed the failing MCP safety contract gate: the tool_handler server version was still 0.2.2 while Cargo was bumped to 0.2.3 — now aligned.

Thanks for the clarification, avifenesh. It sounds like the workflow is correctly configured and the version alignment issue is resolved. The updates to the changelog and the version bumps across the codebase look correct and consistent with the project's versioning strategy.
