feat: update website to reflect full session monitoring capabilities

Rebrand from "TUI launcher" to "multi-project session monitor". Add
usage tracking and idle sessions panel sections, new feature blocks
for monitoring/usage/notifications/focus, updated keybindings, and
revised metadata descriptions.
