v0.2.0 — main on reth 2.5 + base-fee floor and EIP-1559 fee settlement

v0.2.0 is the tip of main as of today (3378e0e, on reth v2.5.0) plus the three fee-related fixes that are still open as stacked PRs, and a workspace version bump.

It exists so tiramisu can be redeployed on the current codebase without waiting for those PRs to merge.

What's in it

Everything on main today — most notably the reth v2.2.0 → v2.5.0 upgrade (#78), the StateManager abstraction (#85), and the protocol-constants / arkiv_* RPC reorganisation (#79) — and on top of that:

• #94 — feat(chainspec): floor the base fee at the genesis base fee
  New arkiv-reth-chainspec crate: ArkivChainSpec overrides EthChainSpec::next_block_base_fee with max(eip1559(parent), genesis.baseFeePerGas). Every base-fee consumer in reth (payload builder, consensus validation, tx pool, eth_gasPrice / eth_feeHistory) goes through that one method, so the floor applies everywhere by construction. Without it an idle chain decays 12.5% per empty block down to the 7 wei protocol minimum.
• #95 — fix(executor): settle fees as EIP-1559 — effective price, tip to beneficiary
  The no-EVM executor now charges the effective gas price and pays the priority tip to the block beneficiary, instead of burning the whole fee.
• #98 — fix(executor): skip the gas balance bound when fee charging is disabled
  With fee charging off, the executor no longer bounds execution by the sender's gas balance.

Plus chore(release): workspace version 0.1.0 → 0.2.0.

⚠️ Consensus-breaking against v0.1.0

Both the base-fee floor and the fee-settlement change alter block validity. A v0.1.0 node rejects blocks produced under these rules, and vice versa. So:

• every producer and watcher of a network must be upgraded together, and
• existing chains cannot be continued across the upgrade — they have to be started fresh.
