/**
 * Single-finger gesture disambiguation for touch look controls: one touch
 * stream drives look-drag, tap, and long-press-hold without fighting.
 * Movement past the tap threshold commits the gesture to "look" and cancels
 * tap/hold; a still finger that lifts quickly is a tap; a still finger held
 * past the long-press delay is a hold. Timestamps are injected so the state
 * machine stays pure; the capture layer owns timers and touch identifiers.
