feat(jfrog): make workspace configuration optional

[Edd88-pixel]

Why

The JFrog modules always ran workspace setup, installed or configured jf, and required package manager configuration even when callers only needed an access token for another Terraform resource.

Closes #71.

Changes

• Add independent options for installing and configuring the JFrog CLI in both JFrog modules while preserving the existing default behavior.
• Make package_managers optional and use an empty value as the single source of truth for disabling package manager configuration.
• Create coder_script.jfrog only when CLI installation, CLI configuration, package manager configuration, or code-server setup is requested.
• Keep OAuth access-token validation active in token-only mode.
• Fail fast with a clear error when jf is required but unavailable, and fix the code-server wait timeout counter.
• Document token-only and preinstalled-CLI usage and add regression coverage for default, token-only, and package-manager-only modes.

Validation

• terraform test -no-color in jfrog-token: 3 passed, 0 failed.
• terraform test -no-color in jfrog-oauth: 13 passed, 0 failed.
• bun test main.test.ts in jfrog-token: 11 passed, 0 failed, 36 assertions.
• terraform validate -no-color in both modules: passed.
• go run ./cmd/readmevalidation: passed for contributor, module, template, and skill READMEs.
• bun run fmt:ci, bash -n, ShellCheck at warning severity, and git diff --check: passed.
• Both startup scripts were executed with installation disabled and jf required but unavailable; each exited with status 1 and the expected diagnostic.

Pull request overview

This PR updates the jfrog-token and jfrog-oauth Terraform modules so consumers can obtain scoped/OAuth access tokens without necessarily running workspace startup configuration (installing/configuring jf and/or configuring package managers), while preserving default behavior for existing users.

Changes:

• Added independent flags to control JFrog CLI installation, CLI configuration, and package-manager configuration (defaulting to current behavior).
• Made package_managers optional (default {}) and prevented GOPROXY export when package-manager configuration is disabled.
• Updated READMEs and added/updated regression tests for default behavior and token-only mode.

registry/coder/modules/jfrog-oauth/run.sh:150

• The code-server wait loop above resets counter to 0 on every iteration, so the timeout condition can never be reached and the script may hang indefinitely if /tmp/code-server/bin/code-server never appears. This impacts the code-server path that runs immediately before this new early-exit check.

if [ "${CONFIGURE_CLI}" != "true" ]; then
  exit 0

Please test the module end-to-end, and we can merge it. Our current tests don't cover the end-to-end testing flow. The code looks good to me.
