Setting an in or out point now turns on loopEnabled so the playhead respects the marker instead of running past the out-point. Closes the last open sub-bug of #834. Background: PR #811 wired the work-area RAF loop to read inPoint/outPoint but kept the loop branch gated behind loopEnabled. Default for that flag is false, so users who set markers without first toggling the loop button saw playback sail past the out-point (or, with the L shuttle, overshoot by a few frames before pausing). The original spec for the feature in issue #807 described markers as logic that "constrains the playback engine"; the actual UX did not match that until the toggle was on. Fix: setInPoint and setOutPoint flip loopEnabled to true when given a non-null value. This sits next to the existing "smart setter" behavior already in the store (setting one marker past the other nullifies the counterpart). Clearing a marker with null preserves the current loopEnabled, so a user who manually toggles the loop button stays in control after that point. Tests: full coverage for setInPoint and setOutPoint (none existed before), including overlap nullification, non-finite rejection, auto-enable on set, and preserve-on-clear in both directions.
