fix: revert "mark Id.run as [implicit_reducible]" (#12801) 
This PR reverts https://github.com/leanprover/lean4/pull/12757.

We suspect this caused the v4.29.0-rc5 tag CI to fail. All 6 test jobs
on the tag CI (run
https://github.com/leanprover/lean4/actions/runs/22699133179) are
failing with:
```
PANIC at _private.Lean.Environment.0.Lean.EnvExtension.getStateUnsafe Lean.Environment:1425:6:
called on `async` extension, must set `asyncDecl` or pass `(asyncMode := .local)` to explicitly access local state
```

29 tests fail, affecting deriving, grind, linter, interactive, and pkg
tests. The v4.29.0-rc4 tag CI passed, and the only code changes between
rc4 and rc5 are this PR and
https://github.com/leanprover/lean4/pull/12782. The failure only
manifests in release builds (with `LEAN_VERSION_IS_RELEASE=1` and
`CHECK_OLEAN_VERSION=ON`).
