fix(init): address third round of PR review comments

- Fix lint-rule guard in init.go to use resolved 'tools' slice instead of
  'initTools' global; 'initTools' is empty when --all-tools is used so the
  guard was ineffective, causing duplicate writes when both claude and opencode
  were selected via --all-tools
- Nil out vsixData in runInit test helper and restore it via t.Cleanup to
  prevent installVSCodeExtension from invoking the external 'code' CLI or
  writing .vsix files on CI / dev machines
- Update stale link text in opencode.md ('Cursor / Continue.dev / Windsurf')
  to match the renamed page heading ('Other AI tools')
