1.5.3-c550cc8

FPAntiFreeCam 1.5.3

Line-of-sight Anti-Xray. Ores are sent to the client as the rock around them (stone, deepslate, tuff, netherrack, ...) until the player can actually see them. Xray packs and Xray mods see plain rock where the ores are hidden.
- Each check tests every exposed ore face from the player's eye, and also from the F5 front/back camera, so third-person view doesn't reveal or hide anything wrongly. A camera clipped into a wall can't see through it.
- Ores within a few blocks are always shown, and ores next to a block you break are checked straight away, so you never mine into fake stone.
- Once seen, an ore stays real until you move away (forget-distance), so nothing flickers back to stone.
- Per-world ore lists and height ranges under anti-xray.worlds. Defaults cover all Overworld and Nether ores; the End is off.
- Works alongside FreeCam protection and Smart Fill. Smart Fill never uses a hidden ore as fill material.
Split bypass permissions. fpantifreecam.bypass.freecam and fpantifreecam.bypass.xray bypass one feature each. fpantifreecam.bypass still bypasses both, and setting one of the new nodes to false turns that part back on (e.g. bypass + bypass.freecam: false = Anti-Xray bypass only).
Cleaner /fpac stats. Grouped into Server / Protection / Smart Fill / Anti-Xray / Traffic sections, one setting per row, no chat prefix on every line, short numbers (12.3k).

Reveals are sent as block-change packets grouped per chunk section. Anti-Xray never re-sends whole chunks.
Chunk sections that contain no hidden ore are skipped without scanning their blocks.
Visibility checks run every 5 ticks with a per-player step budget (ray-budget), nearest ores first, and are skipped while the player stands still and doesn't turn.
Bedrock (Geyser) players get at most 256 reveals per check, so Geyser isn't flooded.

Smart Fill and Anti-Xray now share the same line-of-sight code, so both use the same safety checks (no chunk loads, no reading other Folia regions).
An error in Anti-Xray can no longer stop the plugin from enabling, or skip FreeCam hiding on a packet.

Config updates to config-version: 5.4 automatically. A new anti-xray: section is added; your existing settings are kept.
OPs no longer bypass protection automatically. fpantifreecam.admin no longer includes any bypass permission. Give fpantifreecam.bypass (or .bypass.freecam / .bypass.xray) to staff who should be exempt.
If Paper's built-in anti-xray is enabled in a world, the console warns you. Turn one of them off, since running both stacks fake ores on top of ours.
Tested on Purpur 26.2. Spigot and Folia are supported but not tested on a live server yet, so please report any issues.
