v0.2.0 — onboarding & cross-platform hardening

Onboarding, packaging, and cross-platform hardening.

Changed

• fastmcp is now a default dependency; MCP onboarding no longer needs --project in configs.
• README onboarding overhaul; multi-OS CI (Ubuntu / Windows / macOS).

Fixed

• Windows fixes: process termination, scanner backslash paths, SDK temp-file locking, and renpy.exe preference.
• UI project-picker performance and native Windows drive handling.
