Profile mode & pipeline optimizations

New profile mode: cheap (~400 tokens) cross-lap corner tendencies per tyre compound, with auto-picked laps to deep-dive.

--no-prompt flag and a GUI checkbox omit the embedded analysis prompt; --force ignores the report cache.

compare now ships a deterministic, fuel-corrected verdict section (fuel as a range, not a single number).

Corner detection scales its merge gap with track length, so chicanes and long circuits self-tune; race safely dedupes duplicate lap files.
