v0.3.18

Added

• Missing tool bootstrap flow: FCM now detects when a target CLI is absent, offers a minimal in-TUI install confirmation, runs the official global install command, then resumes the selected model launch automatically.

Changed

• TUI readability overhaul across every screen: the main table, Settings, Help, Smart Recommend, Feedback, and Changelog overlays now share a semantic high-contrast theme system instead of a patchwork of hardcoded colors.
• Global theme switching now works for real: press G to cycle auto → dark → light live, and the Settings screen now exposes a visible Global Theme row for the same control.
• Launcher binary resolution: direct tool launches now search PATH plus common user bin directories so a freshly installed CLI can be reused immediately in the same FCM session.

Fixed

• Theme repaint bugs: provider colors, tier colors, separators, badges, cursor highlights, and overlay backgrounds now update immediately when the theme changes instead of keeping stale import-time colors.
