Fix #4355: Make session write lock timeout configurable

- Increase default timeout from 10s to 60s to prevent premature
  termination when multiple subagents compete for session file locks
- Add sessionWriteLockTimeoutMs config option to agent defaults
- Update call sites to use config value when available
- Maintain backwards compatibility for explicit timeoutMs callers

This fixes the issue where subagents would terminate prematurely with
'terminated' error when session write lock timeout (10s) was exceeded
during concurrent subagent execution.
