James e504e4a836 refactor: address simplify review feedback on --example rename
- Add hidden: true to the --template trap arg so it stops cluttering
  --help output. New users never see a flag that's already gone.
- Rename user-facing "template" → "example" in two spinner/error
  strings that survived the first pass: "Failed to scaffold example"
  and "Downloading example".
- Quote the rename-hint's interpolated value so suggested commands
  stay copy-pasteable even when the user passes values that look
  flag-like (e.g., --template "--foo bar").
- Update the init test to match the quoted output.
- Skipped process.execPath spawn swap: the reviewer's suggestion
  assumed vitest runs under bun, but this repo's vitest runs under
  node (node is vitest's interpreter), so process.execPath is node
  and can't load .ts entries. Kept spawn("bun", …) with a comment
  noting why.
