fix: forward --exact flag to Playwright for role, label, and placeholder locators (#402) (#403)

Summary

- The `--exact` flag on `find role`, `find label`, and `find placeholder` was accepted by the CLI but silently dropped by the server. The Zod validation schema, TypeScript types, and action handlers all lacked the `exact` field, so it was stripped before reaching Playwright's `getByRole`, `getByLabel`, and `getByPlaceholder` calls.
- Added `exact` to the schema, types, and handler for all three locators so the flag is forwarded to Playwright as intended.
- Added tests confirming `exact: true` survives protocol parsing for `getbyrole`, `getbylabel`, and `getbyplaceholder`.

Fixes #402
