feat: v0.14.1 — add all tree-sitter language parser dependencies

Add 14 missing tree-sitter language packages (go, rust, java, c, cpp,
c-sharp, ruby, scala, lua, php, elixir, kotlin, objc, swift) as core
dependencies so all 17 supported languages get AST extraction out of
the box. Update doctor command to check all 17 language parsers.
