Convert FOM extract to strategy pattern [AI]

[rfbgo]

This is some nice OOP around fom extraction, that allows for different methods of extraction

In some situations (such as no contexts) this allows us to have an optimized extract that swap out the full scan "forward last wins" and instead read the file backwards and stop early

class BackwardsAnalysisStrategy(AnalysisStrategyBase):
    """Optimized analysis strategy that reads logs backwards and stops early."""

Code Review

This pull request refactors the analysis logic in Ramble by introducing a strategy pattern. It extracts the analysis code from the application base class into a new ramble.analysis package, implementing both the original ForwardAnalysisStrategy and a new, optimized BackwardsAnalysisStrategy that reads log files backwards to allow early termination. Unit tests are also added to verify these strategies. The review feedback highlights a bug in the backwards file reader where leading empty lines could be ignored, and points out potential runtime errors in BackwardsAnalysisStrategy due to missing local imports of ramble.analysis in fallback blocks.
