fix: proper noun detector flagging common phrases like 'Generate Design'

Massively expanded the common words filter — added ~500 common verbs,
nouns, and adjectives that frequently appear capitalized in titles,
headings, UI buttons, and instructions. 'Generate Design', 'Create
Account', 'Search Filter', etc. are no longer flagged as PPI.

Updated both content.js and auto-detect.js with the same word list.
