Dash ability with charges and invulnerability frames

Dash at a fixed speed for a set time in a locked direction, spend and recharge charges one at a time, keep a fraction of the speed on exit and stay invulnerable for a window that can outlast the dash.

Limits to consider

Keeps time and velocity only; the owner applies the velocity and checks is_invulnerable() when taking damage. 2D vectors. The dash does not stop at walls by itself; call cancel() on a collision if needed. Verified with Godot 4.7.2 headless; written against the Godot 4.3 API.
