Toggle Taste learnings displays

Summary

I've had extreme amounts of output from taste.md learnings, so much so that sometimes the output from taste.md is much more that the actually needed output. In such cases it would be handy to have a toggle option to keep toggle taste learning display.

Here is an eg
output is interleaved with taste info + 2 blocks of taste op for each block of actual info

❯ ok then give me a better way 
  explain approach 1 to me     

✻ Thought for 1 second [ctrl+o to expand]

⠶ Approach 1 — sizeof works because the compiler knows the array size at compile time in
  the same scope where it was declared:

  char *a[] = {"hello", "world"};
    size_t n = sizeof(a) / sizeof(a[0]);   // 2

  sizeof(a) gives the total bytes — 2 pointers × 8 bytes = 16 on 64-bit. sizeof(a[0])
  gives one pointer = 8 bytes. 16/8 = 2. It's computed at compile time, no runtime cost,
   no sentinel needed.

  But it only works when a is the actual array. Pass it to a function, it decays to
  char** and sizeof(a) becomes just the pointer size (8), so the trick fails.

  The better way for runtime use: pass the size along with the array.

  void f(char **a, size_t count);

  That's what every real C API does (argc/argv style). It's simple, explicit, never
  reads out of bounds, and you know the count the moment you built the array — no
  guessing, no sentinel, no UB.

 ✻ Worked for 7s

So just to clarify I want taste learning, but I do not want to annoyed by its "learning" each and every time

Expected Behavior

Silent updates to taste.md

Actual Behavior

I asked it to stop showing me these outputs and this is the response.

 TASTE  Learned
 └ Does not want taste-learning updates/pop-ups surfaced or referenced during the
   conversation; still wants the assistant to keep learning their taste silently in the
   background [Confidence 95%]

首先定位负责渲染 TASTE Learned、Reinforced 和 Moved 消息并处理 taste.md 更新的 CLI 代码；该 issue 未指定具体的源文件或测试。添加一个由用户控制的开关，在抑制这些显示的同时保留向 taste.md 的学习，并验证静默更新仍会写入 taste.md，而正常输出不受影响。
