DanZai233/dsh-webask

Adds a button beside the composer and a global hotkey palette (default mod+shift+k) that hand one-off questions to a web chat instead of into the harness context: the draft is lifted out of the composer, copied to the clipboard and opened in the templated URL. Ships target-site presets (DeepSeek, Kimi, Qwen,,, GLM, Gemini), a local question history that can be re-opened, copied, or inserted back into the composer, and a settings tab for site, URL template, hotkey, clipboard and history.
