fix smart title generation from browser window context

The title engine was falling back to "Screen capture" for all browser
captures because it treated the entire browser window title as noise.

Changes:
- stripBrowserNameSuffix: removes "- Google Chrome" / "| Firefox" etc.
  from the end of window titles, leaving just the page title.
  "oracle - Google Search - Google Chrome" → "oracle - Google Search"
  "Oracle | Cloud Applications - Google Chrome" → page title only

- extractSearchQuery: detects "[query] - Google Search" / Bing / etc.
  patterns after stripping the browser suffix, and formats the result
  as "Search for oracle".

- buildCaptureTitle: uses stripped page title + search detection before
  falling through to the "Screen capture" fallback.

- pickBestOcrPhrase: considers the full OCR line (≤80 chars) as a
  candidate with a +35 completeness bonus before splitting on | or ·.
  This preserves "Oracle | Cloud Applications and Cloud Platform" as a
  single phrase instead of breaking it into fragments.

- candidateWords: filters out standalone punctuation tokens (|, ·, •)
  so they don't inflate word-count penalties for compound brand names.

- verbForElementRole: hyperlinks and links now produce "Select" instead
  of "Click"; search box / search field produces "Search for".

Five new unit tests cover: browser title stripping, search query
extraction, full pipe-separated link text, link and search box verbs.
