up: Add --pull and --build flags for Docker Compose parity (#146)

* up: Add --pull and --build flags for Docker Compose parity

Add `--pull` and `--build` options to `cf up` to match Docker Compose
naming conventions. This allows users to pull images or rebuild before
starting without using the separate `update` command.

- `cf up --pull` adds `--pull always` to the compose command
- `cf up --build` adds `--build` to the compose command
- Both flags work together: `cf up --pull --build`

The `update` command remains unchanged as a convenience wrapper.

* Update README.md

* up: Run stacks in parallel when no migration needed

Refactor up_stacks to categorize stacks and run them appropriately:
- Simple stacks (no migration): run in parallel via asyncio.gather
- Multi-host stacks: run in parallel
- Migration stacks: run sequentially for clear output and rollback

This makes `cf up --all` as fast as `cf update --all` for typical use.

* refactor: DRY up command building with build_up_cmd helper

Consolidate all 'up -d' command construction into a single helper
function. Now used by up, update, and operations module.

Added tests for the helper function.

* update: Delegate to up --pull --build

Simplify update command to just call up with pull=True and build=True.
This removes duplication and ensures consistent behavior.
