fix(lint): recognize supported timeline registration forms

[Bortlesboat]

What

Stop warning that a composition has no timeline when it registers one with window.__timelines.c1 = tl or window.__timelines = { c1: tl }. Commented registrations no longer suppress the warning.

Why

Those forms are already recognized by the core lint rule. The contradictory warning suggests adding data-no-timeline to a working composition.

How

Reuse the existing registration patterns after stripping comments. Keep the conservative bracket check for computed keys and logical assignments.

Test plan

• Unit tests added/updated: all 615 lint tests pass with bun run --filter @hyperframes/lint test -- --reporter=dot --maxWorkers=4.
• Manual testing performed: 12 checks against the built Node and browser entry points, executed in Node.
• Documentation updated (not applicable).

Oxlint, oxfmt, the lint package typecheck, and both package builds pass. Earlier runs hit the existing stripJsStringLiterals scaling timing assertion; it also failed on unchanged e5d89f7. The final full run passed.

Post-Deploy Monitoring & Validation

No additional operational monitoring required; this changes static lint diagnostics only.
