Entity Block Drops

Block drops config changes:

• Renamed `replaceDefaultDrops` to `allowCustomDrops`. Old configs still load: missing `allowCustomDrops` defaults to `true`, and `replaceDefaultDrops` is ignored after migration.
•  `allowCustomDrops` controls whether an entry runs custom item drops and `dropCommand`.
• Regeneration and `breakCommand` are unchanged

Fixed:

• `allowDefaultDrops: false` no longer cancels the block break. Canceling `BreakEvent` made the block pop back (looked like instant regen).
•  `allowDefaultDrops` is reserved until vanilla-only loot can be stripped safely; vanilla + custom both drop for now.

Regeneration

• Normal and event configs now include global rows (`Global_Block_Drops.json` / event globals) together with block-specific files, in line with the docs.
• If a block-specific row has `canRegenerate: false`, it overrides regeneration coming only from global rows for that block.
• New global example files default to `canRegenerate: false` so global rules do not turn on regen everywhere by accident.

Commands / UX:

• After `/blockdrops reload`, if blocks are still on the regen schedule, the message mentions `/blockdrops regeneration force`.

Docs

• README / in-game readme text updated for the new flags, regeneration stacking, and `allowDefaultDrops` behavior.
