[BUZZOK-31816] feat: respect APPLICATION_TEMPLATE_GIT_BASE_URL in dr component commands

[Copilot]

All dr component subcommands now replace known DataRobot GitHub base URLs (https://github.com/datarobot-community, https://github.com/datarobot) with APPLICATION_TEMPLATE_GIT_BASE_URL when that env var is set — enabling air-gapped / corporate mirror setups.

Changes

Core helpers — internal/copier/giturl.go (new)

• ApplyGitBaseURL(url) — rewrites a URL's base prefix if the env var is set; handles both DataRobot GitHub orgs, strips trailing slash, no-ops when unset or prefix unrecognised
• RewriteSrcPathIfNeeded(yamlFile) — patches _src_path in an existing copier answers file in-place; no-op when env var is unset or URL already uses the custom base

dr component add

• ApplyGitBaseURL applied to the resolved repo URL before passing to copier, so newly-added components write the correct _src_path from the start

dr component update (CLI + TUI flows)

• RewriteSrcPathIfNeeded called before copier update, migrating legacy answers files that still contain old GitHub URLs
• Applies in both the runUpdate (non-interactive) path and the TUI updateComponent path

dr component list (indirect)

• ComponentDetailsByURL index in init() now also registers the remapped URL variant, so component-name resolution continues to work after answers files have been rewritten

export APPLICATION_TEMPLATE_GIT_BASE_URL=https://gitlab.internal.corp/datarobot-mirror

# add: copier receives the mirror URL; answers file written with mirror URL
dr component add agent

# update: _src_path in .datarobot/answers/*.yml rewritten before copier runs
dr component update

@copilot can you move rewriting action in a separate command dr component rewrite-config

@copilot can you move rewriting action in a separate command dr component rewrite-config

Done. The rewriting logic has been moved to a new dr component rewrite-config command (commit feat: add dr component rewrite-config command for URL migration). The automatic RewriteSrcPathIfNeeded calls have been removed from both the runUpdate path and the TUI updateComponent path, so the migration is now an explicit opt-in step.

Done in commit docs: update command and dev docs for rewrite-config and APPLICATION_TEMPLATE_GIT_BASE_URL:

• docs/commands/component-managed-updates.md — new "Component Rewrite-Config" section explaining the APPLICATION_TEMPLATE_GIT_BASE_URL air-gapped/mirror workflow and the one-time dr component rewrite-config migration step.
• docs/commands/README.md — rewrite-config added to the command tree, quick-examples block, command-details list, and the environment variables table.

@copilot check that value we get from APPLICATION_TEMPLATE_GIT_BASE_URL has no trailing slash, and remove it if it is

This is already handled — ApplyGitBaseURL calls strings.TrimRight(baseURL, "/") before using the value (see internal/copier/giturl.go line 45), and there's a dedicated test case covering it: "env var set – trailing slash in env var is trimmed".
