feat(google): 19 product APIs — initial Google SDK + Scrapingdog parity

First commit landing the `src/google` module as a tracked tree. Ships
the full Google Scraper surface plus the 7 Scrapingdog parity items
we added server-side in scrape-badger/scrapebadger#135:

- `client.google.search` — web SERP, with optional `ai_overview: true`
  that chases Google's deferred AI Overview page_token.
- `client.google.maps` — search, place, reviews, photos, posts.
- `client.google.news` — search, topics, trending.
- `client.google.hotels` — search, details.
- `client.google.trends` — interest, regions, related, trending, and
  **topic `autocomplete`** (categorized Knowledge Graph entities).
- `client.google.jobs`, `shopping` (with merchant URL click
  enrichment), `patents`.
- `client.google.scholar` — search, **profiles**, **author**,
  **authorCitation**, **cite** (MLA / APA / Chicago / Harvard /
  Vancouver formats with BibTeX / RIS / EndNote / RefWorks export
  links).
- `client.google.autocomplete`, `images`, `videos`, `finance`,
  `aiMode`, `lens`.
- `client.google.local` — **new.** Local Pack business listings for
  SERP queries with local intent (`tbm=lcl`), driven by
  `q + location/uule` instead of a place_id.
- `client.google.shorts` — **new.** Short-form vertical video results
  (YouTube Shorts, TikTok, Reels) via Google's Shorts SERP mode
  (`udm=39`).
- `client.google.flights` — **new.** One-way, round-trip, and
  multi-city flight search with passenger config, cabin class, stops
  filter, and max-price. Returns `best_flights`, `other_flights`,
  `price_insights`, and per-offer carbon emissions.
- `client.google.products` — immersive product detail.

**19 Google product APIs in total**, matching the monorepo
`/v1/google/*` routes shipped in e823f1a. Fully typed, ESM+CJS
dual-publish, accessible as `client.google.<product>`.

New exported param types: `LocalSearchParams`, `ShortsSearchParams`,
`FlightsSearchParams`, `FlightsTripType`, `FlightsTravelClass`,
`FlightsStopsFilter`, `ScholarProfilesParams`, `ScholarAuthorParams`,
`ScholarAuthorCitationParams`, `ScholarCiteParams`,
`TrendsAutocompleteParams`.

Version: 0.5.1 -> 0.6.0. README + CHANGELOG updated.

161 vitest tests pass (26 google + 135 other), tsup build clean,
eslint + tsc green.

+### Added — Google Scrapingdog parity (refs scrape-badger/scrapebadger#135)
+
+Three new Google product sub-clients and deeper Scholar / Trends / Search surface:
+
+- **`client.google.local`** — Local Pack business listings ranked for a SERP query (`tbm=lcl`). Driven by `q + location/uule`, returns ratings, reviews, addresses, phone numbers, and GPS coordinates. Complementary to the Maps API.
+- **`client.google.shorts`** — Short-form vertical video results (YouTube Shorts, TikTok, Facebook Reels) via Google's Shorts SERP mode (`udm=39`).
+- **`client.google.flights`** — One-way, round-trip, and multi-city flight search with passenger config, cabin class, stops filter, and max-price. Returns `best_flights`, `other_flights`, `price_insights`, and per-offer carbon emissions.
+- **`client.google.scholar.profiles({ mauthors })`** — Author profile search by name with `after_author` / `before_author` pagination.
+- **`client.google.scholar.author({ author_id })`** — Full author profile (articles, citation stats, co-authors).
+- **`client.google.scholar.authorCitation({ author_id })`** — Citations-per-year chart for a Scholar author.
+- **`client.google.scholar.cite({ q })`** — MLA / APA / Chicago / Harvard / Vancouver citation formats plus export links (BibTeX / RIS / EndNote / RefWorks).
+- **`client.google.trends.autocomplete({ q })`** — Categorized Knowledge Graph topic entities (`mid`, `type`, link) for a query prefix. Distinct from Google Search autocomplete.
+- **`client.google.search.search({ ..., ai_overview: true })`** — Optional flag that chases Google's deferred AI Overview `page_token` with a follow-up fetch and merges the result into `ai_overview`. Adds ~1s and 1 credit only when the SERP actually defers the overview.
+
+New exported param types: `LocalSearchParams`, `ShortsSearchParams`, `FlightsSearchParams`, `FlightsTripType`, `FlightsTravelClass`, `FlightsStopsFilter`, `ScholarProfilesParams`, `ScholarAuthorParams`, `ScholarAuthorCitationParams`, `ScholarCiteParams`, `TrendsAutocompleteParams`.
+
+The Google product roster is now **19** (was 16).
