fix(scripts): stop m3-touch-targets.py reading comments as code

A KDoc line on the dialect picker's row composable, explaining that it used
`Card(onClick = …)` rather than a `Modifier.clickable`, was counted as a bare
clickable chain. The budget is zero, so a sentence about the rule broke
`./gradlew check`. The comment was reworded to get around it, which was the wrong
fix -- the sentence was right -- and it is restored here.

Not a new rule. m3-spacing-positions.py skips `\s*(//|\*|/\*)` and
m3-title-case.py skips the same three prefixes as a startswith tuple; only this
checker was missing the two block-comment ones, having been written with `//`
alone. m3-audit.sh explains the whole problem at NOT_A_COMMENT, where a note
about a hardcoded colour once counted as a colour.

The same function had the mirror bug, which is the dangerous direction. It looked
for minimumInteractiveComponentSize in a two-line window without stripping
comments, so a comment above a real bare `.clickable` that merely mentioned the
modifier would have excused it. A false positive is noise; a silently excused
offender is a miss. Both lines of the window are now read as code only.

Checked against six cases: a bare clickable is still caught, a guard on the same
line and a guard on the line above still excuse one, a starred KDoc no longer
counts, and a real offender under a comment naming the modifier is now caught.
Counts for the tree are unchanged -- 0 before and after -- which was worth
establishing, since a broken detector would also report zero.

A prefix test rather than block tracking, and the limitation is written on the
function: a `/* ... */ `body line not starting with `*` still reads as code.
There are 539 block comments under ui/ and not one such line, because every KDoc
here stars its body, and three identical rules spelled three ways would be worse
than one limitation on the record.
