John KennedyandClaude Opus 4.6 d08be136b2 perf: add benchmark profiling mode and fix quadratic repr bottleneck

Add --profile flag to bench/__main__.py that bypasses pyperf and runs
each benchmark under cProfile, printing per-benchmark hotspot summaries
and writing .prof files for later analysis. Add benchmark-profile and
benchmark-profile-spy Makefile targets.

Fix O(n^2) performance regression in _get_model_input_state where
f-strings eagerly evaluated repr(state) on every call, triggering
pydantic __repr__ across all accumulated messages. Move error message
construction into the error path so repr is only called when needed.
This yields a 3-5x speedup on react_agent_100x benchmarks.
