CliDeck 2.4.0

CliDeck 2.4.0 adds in-app updates and CSV previews, plus fixes for conversation History and prompt pickers.

• Checks for updates when CliDeck starts and periodically afterward. A persistent notification offers Update; Settings also shows update status.
• Recognized global npm installations can update from the app. Active sessions stay open; restart CliDeck when ready to use the new version. Failed checks retry, and failures show recovery instructions.
• Opens CSV files as bounded, read-only table previews, with quoted fields and multiline values, a header toggle, and clear size-limit notices.
• Records newly submitted Claude Code and Codex user messages in conversation History, while reconciling echoes of agent-sent prompts. Existing missing History entries are not backfilled.
• Highlights recognized double-brace saved-prompt placeholders in blue, ignores accidental punctuation in autocomplete queries, and uses the normal hover styling for focused emoji choices.

Install or update with npm install -g clideck@2.4.0, then restart CliDeck. Older versions without update checking need this one manual upgrade.

Validation: 391 backend/UI checks on Node22, 17 update-flow browser checks, a real isolated npm2.3.1-to-2.3.2 upgrade preserving an active terminal, and a fresh2.4.0 installed-tarball smoke test. No live user sessions were restarted.
