Kimi Code CLI version: 0.38.0
OS: Windows

Problem:
A global [thinking].effort is automatically written into config.toml
when switching the main model through /model. This globally overrides
default_effort configured for aliases in [secondary_model.models].

What steps can reproduce the bug?

Steps to reproduce:

1. Define two aliases for the same model:
   • one with default_effort = "low"
   • one with default_effort = "high"
2. Add both aliases to [secondary_model.models].
3. Configure:
   [thinking]
   enabled = true
   and omit the effort field.
4. Start or reload the TUI.
5. Switch the main model through /model without explicitly changing
   the thinking effort.
6. Check config.toml.

Actual:
[thinking].effort = "xhigh" is written back automatically.
Subagents then use the global xhigh value instead of their alias-level
default_effort.

What is the expected behavior?

Expected:
Switching the main model should not create a global thinking.effort
unless the user explicitly changes the global default. Per-model
default_effort variants in the secondary model pool should continue
to work.
