Reject Zarcanum inputs and outputs before HF4 instead of letting
unsupported combinations pass semantic validation.
Also restrict PoS miner stake inputs to txin_to_key pre-HF4 and
txin_zc post-HF4, with regression coverage for the affected paths.

Update go.mod module line, all require/replace directives, and every
.go import path from forge.lthn.ai/core/go-blockchain to
dappco.re/go/core/blockchain. Add replace directives to bridge
dappco.re paths to existing forge.lthn.ai registry during migration.
Update CLAUDE.md, README, and docs to reflect the new module path.

Add ErrBlockVersion as an alias for ErrBlockMajorVersion for clarity.
Add table-driven tests for expectedBlockMajorVersion covering all
hardfork boundaries (HF0 through HF4+) on both mainnet and testnet
schedules. Add standalone checkBlockVersion tests with Good/Bad/Ugly
pattern including version 255 edge case and exact HF1 boundary checks.

Adds expectedBlockMajorVersion and checkBlockVersion, called from
ValidateBlock before timestamp validation. Block version must match
the fork era: HF0->0, HF1->1, HF3->2, HF4+->3.
Tests cover both mainnet and testnet fork schedules including
boundary heights.

ValidateBlock combines timestamp, miner tx, and reward checks into
a single entry point for block-level consensus validation.

ValidateBlockReward checks miner tx output sum against expected reward
with size penalty and hardfork-aware fee treatment.

ValidateMinerTx checks genesis input height, input count (1 for PoW,
2 for PoS), and stake input type per hardfork version.
