Merge pull request #18 from bmohan01/timeouts

Drop the inline comments in validate() and newStateStorageFromStates that explained terminal-state Timeout semantics and the channel-buffer clamp; both behaviors are already pinned down by tests, making the prose redundant per maintainer preference for documenting behavior with tests rather than narrative comments.

Drop the validate() rejection of Timeout on a terminal state and add a positive test that it is silently ignored at runtime, supporting the iterative-development pattern of flipping a state's Terminal flag without having to also strip its Timeout.

Address review feedback on PR #18: refactor StateExec, broaden validation tests, and fix a pre-existing channel-buffer panic surfaced by the new tests.
