Codex Session Observatory v1.2.0

This release renames the application to Codex Session Observatory, adds per-message timestamps, and completes the application identity cleanup.

Per-message timestamps

• Added local date and time to individual transcript messages.
• Preserved original JSONL timestamps, including messages from sessions resumed on later dates.
• Applied timestamp display across Terminal, Markdown, and DM themes.
• Included timestamps in Capture Transcript.
• Kept messages without valid timestamps free of inferred dates or times.

Application identity and consistency

• Renamed the application from Codex JSONL Observatory to Codex Session Observatory.
• Updated executable names, portable package metadata, and project references.
• Updated the Tauri application identifier and Windows publisher metadata.
• Added a distinct notice for unpublished development versions.
• Refined the initial screen layout across all themes.
• Consolidated the shared timestamp formatter in TypeScript.

Worklog export compatibility

• Changed the Worklog generator identifier from codex-jsonl-observatory to codex-session-observatory.
• Worklog bundles created by earlier versions cannot be refreshed in place by v1.2.0.
• Existing Worklog files remain unchanged when a refresh is rejected. Select a new export destination to create a Worklog with v1.2.0.

Using v1.2.0 or later is recommended for future Worklog exports and management.

This remains a portable Windows release with no installer or automatic update behavior.
