fix(lint): detect over-constrained clip positioning

[miguel-heygen]

Summary

Custom-positioned .clip elements now receive a lint warning before inherited inset: 0 silently stretches them into giant shapes. The rule identifies auto-sized clips that retain both horizontal or vertical edges, and points authors to the exact auto resets or explicit dimensions needed. Full-canvas clips and custom clips with the documented resets or dimensions remain clean.

Test plan

• bun test packages/lint/src — 354 passed
• bun run --filter @hyperframes/lint typecheck
• bunx oxfmt --check packages/lint/src/rules/core.ts packages/lint/src/rules/core.test.ts
• bunx oxlint packages/lint/src/rules/core.ts packages/lint/src/rules/core.test.ts
• bun run build
• Reproduced the original fixture through the built CLI and confirmed clip_inset_overconstrained
