chore(baker/prebake): Add comprehensive documentation to prebake module

- Document prebake.rs, bootstrap.rs, and hook.rs with module-level and
  function-level docs
- Rename parse_prebake_config to parse for conciseness
- Change bootstrap() return type from ExecutionResult to ()
- Add dry-run support to bootstrap stage
- Improve test robustness with Docker availability check and unique
  container names

+//! Prebake workflow orchestration module.
+//!
+//! This module provides the main prebake workflow execution logic, orchestrating
+//! the various stages of build environment preparation.
+//!
+//! # Stages
+//!
+//! The prebake workflow executes the following stages in order:
+//!
+//! 1. **Bootstrap**: Sets up the build environment (user, workspace, privileges)
+//! 2. **EarlyHook**: Executes user-defined commands before dependency installation
+//! 3. **DepsSystem**: Installs system-level package dependencies
+//! 4. **DepsUser**: Installs user-level dependencies
+//! 5. **LateHook**: Executes user-defined commands after dependency installation
+//! 6. **Ready**: Signals completion of the prebake workflow
+//!
+//! # Usage
+//!
+//! ```ignore
+//! let result = prebake("/path/to/prebake.yml", &cli, None).await;
+//! ```
