Add dated-folder extension

[fanhefeng]

Description

Dated Folder adds one no-view command, Create Dated Folder: it creates a folder named after today's date (e.g. 2026-08-28) inside a parent folder of your choice and opens it straight in a terminal. It is meant for the "I need somewhere to put today's scratch work" moment — one keystroke instead of mkdir + cd + opening a terminal window.

Preferences:

• Parent Folder (directory) — defaults to ~/Desktop/temp when empty.
• Terminal (appPicker) — any installed app. When empty, the extension follows the terminal registered in LaunchServices as the shell-role handler for public.unix-executable, which is exactly what Ghostty / iTerm2 / Warp write when you accept "make this your default terminal". Falls back to Terminal.app.
• Folder Name Format (textfield) — yyyy, MM, dd, HH, mm, ss tokens; / nests folders (yyyy/MM/dd). Names containing .. segments are rejected so a format string can never escape the parent folder.
• Reveal (checkbox) — also reveal the folder in Finder.

No network access, no binaries, no third-party dependencies beyond @raycast/api / @raycast/utils.

platforms is ["macOS"] only. A Windows launcher is already in src/lib.ts (Windows Terminal via wt.exe -d, other shells via start /d, Desktop resolved from the known-folder registry entry so OneDrive redirection is respected), but it has not been exercised on a real Windows machine yet, so the extension does not claim support it cannot back. Windows will be enabled in a follow-up PR after manual QA.

Screencast

The command has no UI of its own (no-view): it creates the folder, opens the terminal, and confirms with a HUD such as 📂 Ghostty → ~/Desktop/temp/2026-08-28.

Checklist

• I read the extension guidelines
• I read the documentation about publishing
• I ran npm run build and tested this distribution build in Raycast
• I checked that files in the assets folder are used by the extension itself
• I checked that assets used in the README are located outside the metadata folder if they were not generated with our metadata tool

Greptile Summary

The PR adds the macOS-only Dated Folder extension, which creates a date-formatted directory and opens it in a selected or system-default terminal.

• Adds a no-view command with configurable parent folder, date format, terminal, and Finder reveal behavior.
• Adds path-containment validation and LaunchServices-based default-terminal selection.
• Includes the extension manifest, lockfile, documentation, changelog, icon, and standard tooling configuration.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; the generated preference type issue is fixed, and the updated terminal selection follows the newest numeric LaunchServices modification date as described in the resolved thread.
