refactor(runtime): introduce block executor

[clearloop]

2026-05-23T18:14:12.359922Z  INFO fuzz target starting: spec=tiny, data_path=/tmp/jam_fuzz, socket=/tmp/jam_fuzz/fuzz.sock, vm=interpreter, cpu="AMD Ryzen Threadripper PRO 7995WX 96-Cores" (96 cores), ram=251.2 GB

NOTE: the more coordinations we introduce, the more tax we are paying to the 96-cores machine, stop optimizing now, as the result, interpreter version is clearly faster than the compiler version, even for our interpreter, we are slower than other interpreter now though on consumer machines our interpreters are way faster than others. not sure if it is manly caused by "rayon" but we have already capped the threads to 32.

won't do more optimizations.

Changes

• introduce block state transition executor
• post batch verifications for assurances/guarantees
• batch verification for disputes
• wire multi-tree for TestChain
• clean the version generation logic
