v0.2.5

feat: two-layer energy model — observe pays append_cost (v0.2.5)

Energy cost split into action_cost (operation semantics) + append_cost
(physical recording cost). Observe action_cost remains 0, but all actions
including observe now pay append_cost (1 + payload_bytes/1024). This
reflects the Landauer principle: recording to the Merkle tree has
irreducible physical cost regardless of action type.

- action.rs: quote_cost returns action_cost + append_cost
- kernel.rs: remove observe exemption from energy reservation
- Tests updated for +1 append_cost on all actions

v0.2.4

feat: remove kernel.lock, default state dir to ~/.punkgo/state

- Remove file-based kernel.lock from StateStore; SQLite WAL handles
  concurrent access and IPC endpoint binding prevents duplicate daemons.
  Eliminates stale lock files after crashes.
- Change KernelConfig default state_dir from ./state to ~/.punkgo/state
  with PUNKGO_STATE_DIR env var override for custom deployments.
- Bump version to 0.2.4.
