refactor(vscode): remove unused extension code

[marius-kilocode]

The VS Code extension retained several implementations that no production entry point could reach. Most of the volume came from old Continue autocomplete collectors and transforms, including a permanently disabled IDE/LSP snippet branch, disabled diff snippets, and helpers exercised only by their own tests. Smaller unused query methods remained in autocomplete, browser automation, KiloClaw, marketplace, and session status code.

This change only removes those unreachable paths and their obsolete tests. The active autocomplete collector, context sources, template rendering, bracket filtering, browser automation registration, KiloClaw event flow, marketplace cache, and session status synchronization remain in place. Focused tests continue to cover the surviving autocomplete behavior rather than the retired implementations.
