[williamsharkey]

Feature Request

Add Lens.help() that returns a concise cheat sheet for the Happy Path.

Proposed Output

Lens.help() ->
"HAPPY PATH CHEAT SHEET
======================
Navigation:
  state()         Desktop overview
  files()         List saved files  
  open('path')    Open in Studio

Reading (token-efficient):
  code(1, 20)     Lines 1-20 with numbers
  line(42)        Just line 42
  grep('pat')     Find matches

Editing (surgical):
  setLine(42, 'x')   Replace line
  insertLine(5, 'x') Insert at line
  deleteLine(10)     Delete line
  replace('a', 'b')  Find/replace all

Execution:
  save()          Save to disk
  run()           Execute as app

Example workflow:
  grep('bug') -> code(40,5) -> setLine(42,'fix') -> run()
