Cli add app CRUS and whoami and improve CLI speed by lazy loading

[zeiler]

This pull request introduces several improvements and new features to the CLI, focusing on lazy command loading, enhanced user context handling, new app management commands, and expanded test coverage for configuration logic. The most important changes are grouped below by theme.

CLI Command Loading and Structure

• Introduced the LazyAliasedGroup class in clarifai/utils/cli.py, enabling lazy loading of CLI command modules for improved startup performance and command aliasing. All CLI groups now use this class instead of AliasedGroup. ([[1]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-e3cafb4277139ff82e1f80b80b5dcc839f4420b365d79d97c44206e151e6eeb1R329-R371), [[2]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-6b11868a510d65b7b8d2550d7a614cfad49fc8e5d709a9ef529343281c74edffL9-R19), [[3]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-6b11868a510d65b7b8d2550d7a614cfad49fc8e5d709a9ef529343281c74edffL61-R65))
• Removed eager loading of command modules in clarifai/cli/base.py, now handled lazily by LazyAliasedGroup. ([clarifai/cli/base.pyL542-R594](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-6b11868a510d65b7b8d2550d7a614cfad49fc8e5d709a9ef529343281c74edffL542-R594))

App Management CLI

• Added a new app command group to clarifai/cli/app.py for managing apps, including subcommands for creating, listing, and deleting apps. ([clarifai/cli/app.pyR1-R85](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-cf5647745ef431e4ab42c5bc51105695bc858a6cec995cbb2fec5adcfd1005dfR1-R85))

User Context and Authentication

• Added a whoami command to clarifai/cli/base.py to display both the context user ID and the authenticated user ID, with warning if they differ. ([clarifai/cli/base.pyR127-R174](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-6b11868a510d65b7b8d2550d7a614cfad49fc8e5d709a9ef529343281c74edffR127-R174))

Artifact and Pipeline Template Command Refactoring

• Moved imports for artifact and template management modules inside functions for improved lazy loading and startup performance. ([[1]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-d4cd19419e77075aa0829215b5c2bb2833fba3fb9ff58af1936bfca062ec4bc4L8-L13), [[2]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-d4cd19419e77075aa0829215b5c2bb2833fba3fb9ff58af1936bfca062ec4bc4R139-R140), [[3]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-d4cd19419e77075aa0829215b5c2bb2833fba3fb9ff58af1936bfca062ec4bc4R179-R182), [[4]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-d4cd19419e77075aa0829215b5c2bb2833fba3fb9ff58af1936bfca062ec4bc4R235-R240), [[5]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-d4cd19419e77075aa0829215b5c2bb2833fba3fb9ff58af1936bfca062ec4bc4R339-R343), [[6]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-d4cd19419e77075aa0829215b5c2bb2833fba3fb9ff58af1936bfca062ec4bc4R416-R418), [[7]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-c0f2809b0d9330cda23fba6162e0480c54a12740673a16086a03bfffe19371dfL10), [[8]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-c0f2809b0d9330cda23fba6162e0480c54a12740673a16086a03bfffe19371dfR39-R40), [[9]](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-c0f2809b0d9330cda23fba6162e0480c54a12740673a16086a03bfffe19371dfR106-R107))

Configuration Logic and Testing

• Added comprehensive unit tests for the Config and Context classes in tests/client/test_config.py, covering environment variable overrides, direct access, fallbacks, and error handling. ([tests/client/test_config.pyR1-R232](https://github.com/Clarifai/clarifai-python/pull/958/files#diff-0774976c767ba9cc7410392dbf26231bcefdfd529d2dbe133c48af538d311c5bR1-R232))

@copilot can you fix the errors from https://github.com/Clarifai/clarifai-python/actions/runs/22261474947/job/64400373261?pr=958 i suspect that the new config test is clobbering the CLARIFAI_PAT and other env vars

[Copilot]

@zeiler I've opened a new pull request, #959, to work on those changes. Once the pull request is ready, I'll request review from you.
