fix: dashboard null crash, chat layout, markdown escaping, gzip, gateway banner delay

feat: hosted agent with auto-stop, context compression, visual sliders
feat: auto-reload gateway after config save (debounced 3s)
style: toast solid bg, chat input enlargement, hosted agent panel CSS
chore: fix dev.ps1 encoding, engagement share text
