fix(eslint): disable test/prefer-lowercase-title — it mangles acronyms — 0.1.3

antfu enables `test/prefer-lowercase-title`, whose autofix lowercases the first
character of every describe/it title: `POST` -> `pOST`, `RLS` -> `rLS`,
`Clerk` -> `clerk`. Test titles are descriptive sentences that legitimately open
with acronyms and proper nouns, and no rule option preserves them (only
`allowedPrefixes`, which would have to enumerate every acronym). The rule buys
trivial consistency at the cost of silently corrupting meaning, so it is off for
test files. Regression fixture: uppercase-opening titles must not trip it.
