Remove text_decorations from public API schema

[Copilot]

The text_decorations parameter (colloquially "broken vowels" - controls diacritical marks in search results) was exposed in the public API schema but is an advanced parameter users rarely need to configure.

Changes:

• Removed text_decorations field from baseSearchSchema in src/brave-api.ts

The Brave Search API will now use default text decoration behavior. This simplifies the public API surface without impacting functionality since the parameter was optional.

// Before
export const baseSearchSchema = z.object({
  q: z.string().describe('The search query'),
  // ... other fields ...
  text_decorations: z.boolean().optional().describe('Include text decorations in results'),
  spellcheck: z.boolean().optional().describe('Enable spell checking'),
});

// After
export const baseSearchSchema = z.object({
  q: z.string().describe('The search query'),
  // ... other fields ...
  spellcheck: z.boolean().optional().describe('Enable spell checking'),
});

Original prompt

Should I make broken vowels private
