friel-openai 776246c3f5 Make forked agent spawns keep parent model config (#17247 )

## Summary

When a `spawn_agent` call does a full-history fork, keep the parent's
effective agent type and model configuration instead of applying child
role/model overrides.

This is the minimal config-inheritance slice of #16055. Prompt-cache key
inheritance and MCP tool-surface stability are split into follow-up PRs.

## Design

- Reject `agent_type`, `model`, and `reasoning_effort` for v1
`fork_context` spawns.
- Reject `agent_type`, `model`, and `reasoning_effort` for v2
`fork_turns = "all"` spawns.
- Keep v2 partial-history forks (`fork_turns = "N"`) configurable;
requested model/reasoning overrides and role config still apply there.
- Keep non-forked spawn behavior unchanged.

## Tests

- `cargo +1.93.1 test -p codex-core spawn_agent_fork_context --lib`
- `cargo +1.93.1 test -p codex-core multi_agent_v2_spawn_fork_turns
--lib`
- `cargo +1.93.1 test -p codex-core
multi_agent_v2_spawn_partial_fork_turns_allows_agent_type_override
--lib`
