feat(tools): add var_github_token support with token validation

- Add var_github_token to all VAR_WHITELIST arrays in build.func so the
  token can be set via default.vars, app.vars, or environment variable
- Map var_github_token -> GITHUB_TOKEN in default_var_settings() (env
  variable takes precedence over the var file value)
- Add commented var_github_token example to the default.vars template
- Add validate_github_token() to tools.func:
    * Calls GET /user to verify the token is accepted
    * Reports expiry date from x-oauth-expiry header (fine-grained PATs)
    * Warns when classic PAT is missing public_repo scope
    * Returns distinct exit codes: 0=valid, 1=invalid/expired, 2=no scope, 3=error
- Update prompt_for_github_token():
    * Non-interactive path now picks up var_github_token automatically
    * Interactive path also picks up var_github_token without prompting
    * Validates token immediately after entry; loops until valid or Ctrl+C
