Behavior change: with both NO_COLOR and FORCE_COLOR set, doctor now follows NO_COLOR, the same as the update notices.

• In src/utils/terminal.ts, an empty NO_COLOR value still disables color. Check that the value is non-empty before disabling it.
• In src/__tests__/utils/spinner.test.ts, the assertion can pass with an incorrect frame count. Assert the exact sequence length.

Check if these issues are valid — if so, understand the root cause of each and fix them. When an issue isn't valid or won't be fixed in this PR, reply in its thread with the reason and then resolve the thread. If appropriate, use sub-agents to investigate and fix each issue separately.

<violation number="1" location="src/__tests__/utils/spinner.test.ts:85">
P3: This assertion is looser than the deterministic behavior. Under fake timers the sequence is exactly three frames, then the clear, then the final line, so assert the exact length to catch regressions in frame count.</violation>

<file name="src/utils/terminal.ts">

<violation number="1" location="src/utils/terminal.ts:10">
P3: `NO_COLOR` should only disable color when it is non-empty, per the no-color.org convention this change follows. Check `process.env.NO_COLOR` truthiness (non-empty) instead of `!== undefined`.</violation>

<sub>Shadow auto-approve: would auto-approve. Fixes CLI progress output when stderr is not a terminal by printing plain lines only when the message changes, and centralizes TTY-aware color handling; a focused, tested bug fix with no rollout, policy, or contract change.
