pi-ts-aperture: v0.5.0

Minor Changes

• b51d282: Rewrite extension architecture. Moves core logic to src/lib/, introduces ApertureRuntime class with dependency injection, replaces lifecycle hooks with session_start + onSync callback pattern, and adds provider unregistration with user notification.
• 00ba115: Add streamSimple wrapper that sends x-session-id header with the Pi session ID. This groups all requests from the same Pi session together in the Aperture dashboard.

Patch Changes

• cda19d3: Drop models from registerProvider call. Rely on the baseUrl-override path instead, which preserves built-in model definitions (reasoning, compat, thinking levels) and only updates the endpoint URL.
