ripgrep-search-discipline — search code at ripgrep speed, not grep speed

Core insight: rg is gitignore-aware, parallel, and Unicode-correct by default. Reaching for grep -r or find | xargs grep throws all three away. Default to rg.

⚠️ Critical Constraints

• Default to rg, never grep -r or find … -exec grep. Why: rg walks the tree in parallel, skips .git/, node_modules/, and everything in .gitignore automatically, and is typically 5–50× faster.

  # WRONG — slow, scans ignored dirs, no parallelism
  grep -rn "parseConfig" .
  find . -name '*.go' -exec grep -l "parseConfig" {} +
  # CORRECT
  rg "parseConfig"
  rg -t go "parseConfig"
