Added: travel_short_distance_acceleration print setting (ported from Bambu Studio)

Default: 250 mm/s²
Disable: set to 0

UI

New option in Speed → Acceleration
- Label: Short travel

Behavior
Short-travel acceleration is applied during G-code generation for:

non-first-layer travel moves
travels near erExternalPerimeter / erOverhangPerimeter
travel distance below retraction_minimum_travel

Threshold logic:
travel.length() < retraction_minimum_travel
(internally scaled units)

Testing

Tested on macOS ARM
G-code A/B test (Benchy):
- ON: emits SET_VELOCITY_LIMIT ACCEL=250 on short travels before outer-wall sections
- OFF: no 250 accel switches emitted
No change to base travel acceleration otherwise
