fix: address review findings on formula templates and BOOTSTRAP docs

- upgrade-dependency.toml: fix forge upgrade command (forge update, not
  forge install); remove redundant `npm install` after lockfile write;
  simplify description to "Upgrade {{package}} to {{to_version}}" so it
  reads cleanly when from_version is omitted
- add-rpc-method.toml: remove dead `namespace` variable; inline namespace
  derivation logic into register-method step description
- BOOTSTRAP.md: mark formula label entry as requiring feat/formula merge;
  add YAML front matter example so operators know the issue schema
