[Bug] Color-disabled normal output still contains ANSI reset codes

[equationzhao]

Describe the bug
Color-disabled output still contains ANSI escape sequences. This pollutes plain text output and downstream processing.

To Reproduce

1. Build the current repository:

go build -o /tmp/g-bug-audit .

2. Create a single file:

tmp=$(mktemp -d)
printf 'x' > "$tmp/a.txt"

3. Disable colors and inspect control bytes:

/tmp/g-bug-audit --no-config --disable-index --color never --no-icon -A --byline "$tmp" | cat -v
printf '\nexit=%s tmp=%s\n' ${pipestatus[1]:-${PIPESTATUS[0]}} "$tmp"

4. Actual output:

a.txt^[[0m

exit=0 tmp=/var/folders/1b/57vdxmgj7s1glqm6tbsw1frm0000gn/T/tmp.9F4PuG3JXL

5. The same problem reproduces with --no-color:

a.txt^[[0m

exit=0 tmp=/var/folders/1b/57vdxmgj7s1glqm6tbsw1frm0000gn/T/tmp.44e4AcyKW4

6. Expected output:

a.txt

No ESC[0m should be present when color is disabled.

Screenshots
Not applicable.

Info (please complete the following information):

• OS: macOS darwin/arm64
• Version: v0.31.2, Go go1.26.1

Additional context
The name rendering path appears to append a reset sequence even when the color level is disabled. --classic does not emit the reset, but --color never and --no-color do.
