The fee split braided two independent concerns into one line: how much of a
fee is kept (a protocol constant, floor(fee/2)) and where the kept part goes
(compiled-in extras.FeeRewardVault = 0x0100..02). The second half made the
destination ungovernable and silently bypassed the RewardManager precompile
the moment FeeSplit activated, so turning the burn on would have DISABLED the
one on-chain knob the chain already has.
Split the concerns:
ratio -> stays a right shift. Fixed, auditable, not settable by any
transaction. Changing it remains a release plus a coordinated
fork, deliberately: monetary policy should not move at the
speed of a multisig.
destination -> the configured coinbase, i.e. BlockChain.GetCoinbaseAt, i.e.
the RewardManager precompile's stored address. Already part of
header validity (dummy.verifyCoinbase), so it is verifiable
from the header and movable by one admin transaction.
creditTxFee collapses to one credit site; extras.FeeRewardVault is deleted.
Also adds the ordering gate this created a need for: ChainConfig.Verify now
refuses a config that schedules feeSplitTimestamp while rewardManagerConfig is
not enabled at that time (and allowFeeRecipients is off). Without RewardManager
GetCoinbaseAt falls back to the keyless blackhole, so such a config would burn
half of every fee and strand the other half forever -- the C-Chain already has
~3867 LUX stuck at that address. mainnet/cchain.json currently ships exactly
that shape (feeSplitTimestamp 1785715200, no rewardManagerConfig in any of the
49 precompileUpgrades); the node will now refuse to start on it instead.
This is a no-op on every live chain: mainnet 96369's running config has no
feeSplitTimestamp at all (eth_getChainConfig), the vault balance is 0, and the
branch has never executed. The correction is free today and costs a fork later.
Tests:
core: destination follows the configured coinbase; a redirect mid-chain moves
the whole reward stream while the burn is unchanged; supply conservation
on executed blocks; genesis refuses the ungoverned shape.
dummy: a proposer naming any other coinbase is rejected with ErrInvalidCoinbase,
so crediting the header coinbase is not a validator-capture hole.
extras: the verbatim upgrade.json fragment activating rewardManagerConfig and
feeManagerConfig with the DAO Safe as adminAddresses parses through the
registry, and feeManager's governable surface contains no ratio.

Breaking change: This removes all SubnetEVM naming - only "EVM" is supported.
No backward compatibility maintained as per user requirement.
When tests use SnapshotNoBuild: true with SnapshotLimit > 0, snapshot
layers are initialized but not built for new blocks. Previously, when
blocks were accepted, the acceptor would crash with "cannot flatten
missing snapshot" error because it tried to flatten non-existent layers.
This fix adds:
- HasBlockLayer(blockHash) method to snapshot.Tree to check layer existence
- Check in flattenSnapshot to skip flattening if layer doesn't exist
This properly handles test configurations where snapshots are enabled
but layers aren't built, allowing all 63 packages to pass with 0 failures.

This allows the project structure to align with v0.7.5 requirements
but the build still needs additional work to be fully functional.
Updated all copyright headers from "Lux Partners Limited" to "Lux Industries Inc" and updated the year to 2025 to reflect the new holding company structure.
The `types` package now only contains `coreth` logic an nothing from upstream so it shouldn't live in the same location in the repo.
Automated:
```shell
$ git mv core/types plugin/evm/types
$ find -name '*.go' | xargs sed -i 's|"github.com/ava-labs/coreth/core/types"|"github.com/ava-labs/coreth/plugin/evm/types"|'
$ golangci-lint run --fix
```
See original PR https://github.com/ava-labs/coreth/pull/877
Complete the transition of `core/types` to upstream code.
Note that the previous commit results in _all_ upstream types / vars / consts being in the `imports.go` file. This results in a strict partition of upstream and local identifiers so it is safe to simply change import paths.
1. Globally change all imports from `subnet-evm/core/types` to `libevm/core/types`;
2. Rename all `subnet-evm/core/types` imports to `customtypes` for ease of review here;
3. Dot import `libevm/core/types` in tests only to avoid hundreds of noisy changes.
See original PR https://github.com/ava-labs/coreth/pull/875
- `BlockGasCost` getter pure function
- New import from libevm's `core/types`: `Block`, `Blocks`, `Body`, `CalcUncleHash`, `NewBlock` and `NewBlockWithHeader`
- remove now unneeded `core/types/block.go`
