v0.3.0

Added

• lutest setup creates an initial lutest.toml interactively for Lute, Roblox, or both runtimes.
• lutest install-package materializes a Roblox-ready Lutest source package, with an optional output parent directory.
• CLI reference documentation for both commands.

Changed

• The Roblox harness now uses an internal registration context; set_runtime_register is no longer exposed by the public lutest API.
• Roblox library source transformation is shared by the remote bundle and installed package flows.
