FastEdit 1.0.2

Major schematic-paste stability fixes plus in-game quality of life.

✨ New

• Unlimited paste size: large schematics stream in bounded segments
  (constant memory regardless of size — no more OOM). BLOCKS_PER_TICK
  raised to 40k (~800k blocks/s, TPS stays stable).
• Whole-structure undo: a single //undo reverts the entire paste
  at once (transactional). //undo N = N structures. //redo likewise.
• In-game autocomplete (Bedrock): native argument suggestions —
  full block list (//set, //replace, //sphere, //cyl,
  //pyramid, //walls, //brush, //mask), paste flags
  (-noair/--skip-air), sub-commands (//schem save|load|list),
  directions, axes, etc.

🐛 Fixes

• .schem/.schematic pasted as magenta or crashed:
  • Hidden null error → real stack traces in console.
  • UnknownBlocks rewrote the file to disk per block → stall/OOM.
  • Lost orientations: Java→Bedrock state translation (stairs, slabs,
    logs, doors, trapdoors, chest/furnace facing…).
  • Legacy .schematic: metadata (orientation/variant/colour) now
    decoded; block-id table greatly extended.
  • Resolution verified against the live registry: oak_*→base,
    dark_oak signs→darkoak, rooted_dirt→dirt_with_roots,
    tall_seagrass→seagrass, etc. (a wrong name is skipped, never
    mis-placed).
• Crash loop: an out-of-world Y block (AIOOBE) crashed the tick
  forever → now skipped cleanly, the poison job is dropped.
• Missing chunk layers: edited chunks are now marked changed
  (persisted), relit and fully resent to players → 100% of chunks/layers
  present, even far from the player.
• Waterlogged blocks: submerged stairs/fences/coral keep their water
  (Bedrock layer-1, supported in copy/cut/paste + undo).

⚠️ Known limitations

• waterlogged not handled for legacy .schematic (pre-1.13).
• Composite patterns (stone,dirt, 35:2) are underlined client-side
  but still execute normally (no strict param tree, by design).
• Very large pastes (>16M blocks): undo beyond the memory budget evicts
  the oldest segments (anti-crash safeguard).
• Finalization spike at the end of very large pastes (>10k chunks).
