Description
Is your feature request related to a problem?
Currently, resample ignores missing timestamps when operating on a time dimension with a fixed frequency.
Describe the solution you'd like
I want to propose adding a strict argument (accepting ignore, warn, or error) to validate timestamp completeness before resampling.
Please let me know your thoughts.

Research direction
Start by locating xarray's resample entry point and its existing tests. Review how fixed-frequency resampling currently handles missing timestamps, then define the behavior for strict="ignore", "warn", and "error". Done means completeness is validated before resampling and each mode has test coverage.
