fix(logging): move module-level initialization to explicit setup calls (#3874)
- Moved environment variable parsing and `setup_logging()` call from
module level to proper initialization points
- Added explicit `setup_logging()` calls in `server.py::create_app()`
and `library_client.py::AsyncLlamaStackAsLibraryClient.__init__()`

Module-level side effects are bad practice and can cause issues with
import order, testing, and circular dependencies. The previous
implementation ran logging setup on every import of the log module,
which is unpredictable and difficult to control.

chore!: remove model mgmt from CLI for Hugging Face CLI (#3700)
This change removes the `llama model` and `llama download` subcommands
from the CLI, replacing them with recommendations to use the Hugging
Face CLI instead.

Rationale for this change:
- The model management functionality was largely duplicating what
Hugging Face CLI already provides, leading to unnecessary maintenance
overhead (except the download source from Meta?)
- Maintaining our own implementation required fixing bugs and keeping up
with changes in model repositories and download mechanisms
- The Hugging Face CLI is more mature, widely adopted, and better
maintained
- This allows us to focus on the core Llama Stack functionality rather
than reimplementing model management tools

Changes made:
- Removed all model-related CLI commands and their implementations
- Updated documentation to recommend using `huggingface-cli` for model
downloads
- Removed Meta-specific download logic and statements
- Simplified the CLI to focus solely on stack management operations

Users should now use:
- `huggingface-cli download` for downloading models
- `huggingface-cli scan-cache` for listing downloaded models

This is a breaking change as it removes previously available CLI
commands.

chore: more mypy fixes (#2029)
# What does this PR do?

Mainly tried to cover the entire llama_stack/apis directory, we only
have one left. Some excludes were just noop.

Add a verify-download command to llama CLI (#457)
# What does this PR do?

It is important to verify large checkpoints downloaded via `llama model
download` because subtle corruptions can easily happen with large file
system writes. This PR adds a `verify-download` subcommand. Note that
verification itself is a very time consuming process (and will take
several **minutes** for the 405B model), hence this is a separate
subcommand (and not part of the download which can already be
time-consuming) and there are spinners and a bit of a "show" around it
in the implementation.

## Test Plan

API Updates (#73)
* API Keys passed from Client instead of distro configuration

* delete distribution registry

* Rename the "package" word away

* Introduce a "Router" layer for providers

Some providers need to be factorized and considered as thin routing
layers on top of other providers. Consider two examples:

- The inference API should be a routing layer over inference providers,
  routed using the "model" key
- The memory banks API is another instance where various memory bank
  types will be provided by independent providers (e.g., a vector store
  is served by Chroma while a keyvalue memory can be served by Redis or
  PGVector)

This commit introduces a generalized routing layer for this purpose.

* update `apis_to_serve`

* llama_toolchain -> llama_stack

* Codemod from llama_toolchain -> llama_stack

- added providers/registry
- cleaned up api/ subdirectories and moved impls away
- restructured api/api.py
- from llama_stack.apis.<api> import foo should work now
- update imports to do llama_stack.apis.<api>
- update many other imports
- added __init__, fixed some registry imports
- updated registry imports
- create_agentic_system -> create_agent
- AgenticSystem -> Agent

* Moved some stuff out of common/; re-generated OpenAPI spec

* llama-toolchain -> llama-stack (hyphens)

* add control plane API

* add redis adapter + sqlite provider

* move core -> distribution

* Some more toolchain -> stack changes

* small naming shenanigans

* Removing custom tool and agent utilities and moving them client side

* Move control plane to distribution server for now

* Remove control plane from API list

* no codeshield dependency randomly plzzzzz

* Add "fire" as a dependency

* add back event loggers

* stack configure fixes

* use brave instead of bing in the example client

* add init file so it gets packaged

* add init files so it gets packaged

* Update MANIFEST

* bug fix
