BitForge d1aba46e48 fix(entity): reset fall distance on Spectator/Creative gamemode switch (#2382)
* fix(entity): reset fall distance on Spectator/Creative gamemode switch

Prevents fall damage when a player switches to Spectator mid-fall and
then back to Survival before landing.

This is a pragmatic workaround — vanilla achieves this through multiple
independent defense layers (noPhysics, per-tick reset, on_ground force,
mayfly check) rather than an explicit reset. The TODOs in the code
track the remaining gaps for a full vanilla-faithful implementation.

Fixes #2372

* docs(entity): document Creative fall-distance over-forgiveness edge case

Add TODO clarifying that once vanilla fall-damage layers 1-4 are
implemented, the reset should be restricted to Spectator only. In
vanilla a non-flying Creative player keeps fallDistance across a
Survival switch (guarded by abilities.mayfly in causeFallDamage);
resetting here over-forgives that edge case.

* docs: condense fall damage comment to reference vanilla methods

Reduced comment from 23 lines to 6 by:
- Removing detailed explanations of vanilla defense layers
- Directly referencing Player.aiStep() and Player.causeFallDamage()
- Keeping only actionable TODOs
- Switching to /* */ style
