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.

Converts the last 3 fmt.Errorf calls in production code (excluding
crypto/ CGo boundary) to coreerr.E() for conventions consistency.
Co-Authored-By: Charon <charon@lethean.io>
Replace all fmt.Errorf and errors.New in production code with
coreerr.E("Caller.Method", "message", err) from go-log. Replace
os.MkdirAll with coreio.Local.EnsureDir from go-io. Sentinel errors
(consensus/errors.go, wire/varint.go) intentionally kept as errors.New
for errors.Is compatibility.
270 error call sites converted across 38 files. Test files untouched.
crypto/ directory (CGO) untouched.

Rejects non-coinbase transactions during the 60-block window before
HF5 activation. Coinbase transactions are exempt. Implements
IsPreHardforkFreeze and ValidateTransactionInBlock.

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.
Co-Authored-By: Charon <charon@lethean.io>
ValidateMinerTx checks genesis input height, input count (1 for PoW,
2 for PoS), and stake input type per hardfork version.
