Mu-Tsun Tsai 9b72a87c17 fix(lint): remove root_composition_missing_data_duration (#490)
* fix(lint): remove root_composition_missing_data_duration

Lint cannot statically observe the runtime's true Infinity-emission
condition: it requires a finite GSAP timeline duration AND a finite
media/sub-comp window AND timeline > floor + 1, none of which are
visible to the static linter. The looping shapes that drive the
condition are already covered by `gsap_infinite_repeat` and
`gsap_repeat_ceil_overshoot` (both from #243), which point at the
real authoring mistake — flagging the missing duration separately
was a noisy proxy for the same signal.

Per #490 review discussion, deprecate the static rule and let those
two GSAP rules carry the pre-render coverage. If perfect precision
on `durationInFrames = Infinity` is needed, that belongs on the
runtime/render path where `shouldEmitNonDeterministicInf` is
actually known.

Add regression tests pinning the removal: a docs-compliant root
without `data-duration` no longer warns, and the canonical
loop-inflated shape now surfaces only via `gsap_infinite_repeat`
instead of two duplicate findings.

* docs(skills): update step-6 build checklist after rule removal

Drops the `root_composition_missing_data_duration` reference now that
the rule is gone. Keeps the authoring recommendation (and explains the
runtime Infinity case) but points authors at the GSAP rules that
actually carry the lint signal: `gsap_infinite_repeat` and
`gsap_repeat_ceil_overshoot`.
