• change: Sturdier internals, with no UI changes.
• change: Every module now lives in a shared library crate, so the bootstrap, CLI dispatch and direct-connect flows are reachable from tests for the first time.
• change: Startup banner proxy detection is locked down by a unit test, so support bundles keep showing reliable environment context.
• change: Internal seams that used to hide behind a thousand-line entry file now sit behind explicit module boundaries, making future tweaks safer to land.
