fix: track pose-aware player network offsets

[HashimTheArab]

Summary

• Track sneaking, swimming, crawling, gliding, and spin-attack player network offsets.
• Recompute the stored offset when entity metadata changes.
• Add regression coverage for each supported player pose.

Verification

• go test ./entity ./game

This follows the merged entity network-offset normalization work in #150.

Summary by CodeRabbit

• Bug Fixes

  • Improved movement detection for players who are sneaking, swimming, gliding, crawling, sleeping, or performing spin attacks.
  • Adjusted player height calculations to better reflect prone and sneaking poses.

• Tests

  • Added coverage for network offsets across supported player poses.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change adds separate network offsets for sneaking and prone players. networkOffset selects offsets from player pose metadata, and table-driven tests cover seven pose states.

20-25: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Cover stored-offset recomputation after metadata changes.

These tests call networkOffset directly. They do not verify that an existing entity refreshes its stored offset when metadata changes, which is part of the PR objective. Add an entity-level regression test, or confirm that equivalent coverage exists elsewhere.

Addressed the CodeRabbit nit from the previous pass by adding TestEntityUpdateMetadataRefreshesNetworkOffset. It now verifies that changing player metadata updates the entity’s stored network offset for sneaking and swimming poses.

Validation: go test ./... and go vet ./... pass in anticheat.

LGTM, Thanks for the PR!
