Critical: auto-punish could ban legitimate players

If you have punishments.auto-punish enabled, please read this. The threshold was compared against a single check's violations, not the total across all checks as the config described — and it defaulted to 10. Simulation reaches 10 violations on completely honest players as a matter of course (its own alert threshold is 100), so enabling auto-punish would remove real players from your server.

Thresholds are now configured per check, with sensible built-in minimums that protect you even if your config file predates this option. The global default moved from 10 to 100.

False positive fixes

• GroundSpoof no longer flags players whose game window is minimised or sitting in the pause menu. A starved client stops ticking evenly, and its ground status was being judged against ticks it never ran.
• Fixed water and lava currents applying a push the client never made. Below vanilla's cutoff a negligible current was scaled up to a full-strength push — several times larger than the flag threshold, on every tick in flowing water.
• Fixed 1.8–1.13 players drifting on every tick while on the ground: the ground speed calculation was missing the branch those versions use.
• Fixed jump prediction on pre-1.20.5 clients, which read a value those versions do not use, and on pre-1.14 clients using Jump Boost.
• Fixed levitation being mispredicted by the tick-skip estimator.
• Fixed pre-1.17 players in boats and minecarts having their position discarded.
• Fixed swimming predictions offering jumps the player never pressed.
• Book writing no longer flags when the only page is blank.
• Improved precision across fluid levels, diagonal movement and sprinting to match the client exactly.
• Sprint hunger check now runs with settled state and correctly treats 6 food as hungry.
• Added missing collision shapes for potted golden dandelion and sulfur spike.

Fixes

• Fixed "No SLF4J providers were found" errors on startup. Log output from PacketEvents, the connection pool and Redis was being silently discarded; it now reaches the console.

Additions

• Support for 26.2's attribute-driven friction, air drag and bounciness, including the reworked bed and slime bounce. Older clients are unaffected.
• Updated to PacketEvents 2.13.1.
