Replace Q3TA player movement with Quake Live's pmove system, decompiled from qagamex64.so via Ghidra MCP. Struct changes: - playerState_t: +12 bytes (field_08c, field_094, field_09c, lastJumpTime, jumped, crouchSlideTimer, forwardmove/rightmove/upmove) - usercmd_t: +4 bytes (field_15, field_16 between weapon and forwardmove) - pmove_t: +16 bytes (field_0dc/0e0/0e4/0f8, removed framecount) - pml_t: +12 bytes (isJumppad, wallContact, isStepJump) - pm_flags: remapped to QL values (21 flags, several moved/new) New physics systems: - Dual VQ3/PQL physics (PMF_PROMODE) - Double jump, crouch slide, chain/ramp/step jump - Wall contact movement, grapple hook physics - 34 server-tunable pmove_* cvars with cgame prediction sync Network protocol updated for new struct fields and usercmd bytes.
