revert(evm): remove the revmc JIT integration (#227) (#236)

* revert(evm): remove the revmc JIT integration (#227)

Removes the optional revmc JIT execution added in #227 (862ef51) together
with the LLVM 22 toolchain it pulled into every default build, the Docker
image, and CI, plus the apt.llvm.org bootstrap hardening that only existed
to serve it (#229, #234, #235).

Why: compiled code cannot produce Unzen's per-opcode zk-gas metering
(`spec_supports_jit(UNZEN) = false`), and Unzen is active on every
shipped network (mainnet since 2026-08-06, hoodi since 2026-06-18,
devnet/masaya from genesis), so the JIT can never run for a new block
anywhere; pipeline sync never opts in either. What remained was build and
maintenance cost with no measured benefit.

Kept from #227: the beacon-root override plumbing and the non-zero
parent-beacon-root rejection (consensus-relevant riders unrelated to the
JIT), and the removal of the `.github/**` paths-ignore so workflow
changes still run CI. `transact_raw` keeps driving `TaikoEvmHandler`
directly (finalize-before-error on both paths) rather than restoring the
pre-#227 `ExecuteEvm`/`InspectEvm` entry points.

Verified: `just fmt`, `just clippy`, `just test` (283/283) and
`cargo check --workspace --all-features --all-targets --locked`.

* fix(cli): reject --jit for re-execute like the node does

reth's `re-execute` parses its own `JitArgs` and applies them through
`ConfigureEvm::with_jit_support`, which is a no-op for the Taiko config,
so `re-execute --jit` would silently run interpreter-only while
`node --jit` errors. Share one `reject_jit_args` between the executor
builder and the re-execute arm so both fail loudly (review feedback).
