Summary

DbConnection.ConnectionTimeout is a virtual property (defaults to 15 seconds) that is not overridden in FileConnection. For file-based providers, connection timeout should reflect the time allowed to open/parse a file.

What's Needed

Override ConnectionTimeout in FileConnection to:

1. Return a configurable timeout value
2. Add a Connection Timeout keyword to the connection string builders
3. Actually enforce the timeout during Open() (e.g., cancel file parsing if it exceeds the timeout)

Current Behavior

Returns the default 15 seconds from the base class, but this value is never checked or enforced during file operations.
