fix(amazonq): Change JB's behavior back to blocking auto trigger

[andrewyuq]

Non-Cancellable Inline Completion with Session Persistence

These two commits implemented a non-cancellable inline completion system that preserves suggestions across display sessions:

Key Changes:

Added NonCancellable context: Wrapped getSuggestion with NonCancellable to prevent completion requests from being cancelled mid-execution

Implemented session persistence: Maintained activeTriggerSessions map to preserve suggestions from previous trigger sessions that were disposed before completion

Cross-session suggestion display: When a display session is invalidated, suggestions from activeTriggerSessions are carried forward to the next available display session via getVariants()

Asynchronous pagination: Made pagination non-blocking while ensuring suggestions are still delivered to future display sessions

Result: Inline completion suggestions are now guaranteed to be displayed even if the original display session is cancelled or disposed, ensuring users see all generated suggestions in the next available display session.
