Release Management

For automatic release on merge, add one of these labels:

• release:major - Breaking changes, incompatible API changes (bumps 1.x.x → 2.0.0)
• release:minor - New features, backwards-compatible (bumps x.1.x → x.2.0)

No label = No automatic release (manual release via GitHub Actions later)

• Tested on WSL
• Ran ./osa-cli.zsh --scan-secrets (if touching constructors)

Checklist

• My code follows the zsh style of this project
• I have added #!/usr/bin/env zsh shebang to new scripts
• I have updated documentation (if applicable)

• All files use .zsh extension (unless intentionally .sh for bash)
• I have added appropriate release label (release:major or release:minor)

Pull request overview

This PR adds support for installing and initializing depot_tools, a set of utilities required for Chromium development. The implementation registers depot_tools as a new optional component that can be enabled/disabled through configuration files. However, the PR also includes two unrelated utility installation scripts (tree and cmake) and removes a user-specific path from source control.

• Adds depot_tools component with installation script and shell initialization
• Updates all configuration YAML files to include the new depot_tools option
• Modifies CLI to register and handle depot_tools component installation

src/zsh/snippets:1

• This file should not be tracked in git. According to .gitignore line 10, the entire src/zsh/snippets/ directory is intentionally ignored because it contains downloaded snippets installed during setup. This file appears to contain a hardcoded user-specific path (/Users/fre/dev/osa-snippets) which should never be committed. The deletion is correct, but verify this wasn't accidentally committed in a previous change.

Missing shebang at the beginning of the file. All zsh script files must start with #!/usr/bin/env zsh according to the project's coding guidelines.
