jif 7790524d6b Preserve JSON number precision in exec-server RPC messages (#33031)
## Why

Exec-server JSON-RPC payloads can contain decimals, exponent notation, and
integers outside the native 64-bit range. Decoding these values should preserve
their original JSON representation without weakening the existing message
complexity limit.

## What changed

- Enable `serde_json` arbitrary-precision number and raw-value support for the
  exec-server protocol.
- Decode serde's number and raw-value wrappers in the bounded JSON visitor,
  charging nested raw values against the 256K-value limit.
- Select the JSON-RPC envelope variant from its fields after bounded decoding so
  arbitrary-precision values survive message deserialization.

## Testing

Add coverage for exact arbitrary-precision number round trips and for enforcing
the value limit inside raw-value wrappers.
