v0.2.0 Changelog

• per-world management
• better container handling, pick block, and performance
• various minor fixes

Some of these changes inspired by the edits of https://github.com/xiaozhangup/Pipes

Features

• Per-world PipeManager — each world gets its own PipeManager with independent lifecycle; config to enable/disable pipes per world
• Container adapter system — new ContainerAdapter interface with implementations for furnaces (vanilla hopper parity) and brewing stands (no extraction during brewing)
• Path caching & sleep/throttle — cached pipe paths with full-invalidation on topology changes, sleep for idle pipes (empty source / full destination), dead-end recheck cooldown, transfer phase offset to spread load across ticks
• Creative pick-block — middle-clicking a pipe in creative mode now gives the correct pipe item (compatible with HeadSmith)
• CI pipeline — GitHub Actions build + server startup test matrix across Paper 1.21 through 26.1.2

Fixes

• PDC migration — pipe entity tags migrated from scoreboard tags to PersistentDataContainer with automatic migration on chunk load
• Stale variant references — config reload now re-resolves PipeVariant objects; warns if a variant was removed from config
• Duplicate delete_all message — fixed double response when running /pipes delete_all
• Recipe unlock listener on reload — /pipes reload now properly re-registers the recipe unlock listener so config changes take effect

Internal

• Shared adapter helpers (tryInsertSlot, removeFromSlots) extracted to ContainerAdapter interface
• VariantRegistry streamified; added getQueryableManagers()
• WorldManager handles world load/unload lifecycle

• Add help subcommand to /pipes
• Fix default copper pipes recipe result (4 instead of 1)
