Tailwind parser fix and new switch lint

Tailwind arbitrary values now parse parenthesized and unary expressions correctly (bee1e54)

Biome fixed a parser bug that produced invalid syntax trees for Tailwind arbitrary values containing nested parentheses or unary operators, such as w-[calc(1px+(2px))] and w-[calc(1px*-(2px))]. This also required updating generated Tailwind syntax factories and related tests, so downstream class analysis now sees the right AST shape.

New nursery rule rejects nested switch statements (25eb10c)

Biome added noNestedSwitch, a new nursery lint rule that flags switch statements nested inside other switch statements. The rule is wired into config schemas, diagnostics metadata, and ESLint migration support, so it can be enabled and migrated consistently across the toolchain.

Other misc changes

• Refactored shared has_inner_comments handling into a common helper (271d9b2).
• Reverted an earlier Tailwind parser change after the follow-up fix landed (dc2c81d).
• Merge/chore commits and automated fixes, including syncs from main/next and small config/test updates (f0f8242, 6359a9b, 07a576a, 2ebfdd3, 98140cd, fda255b, 45aed7c).
