v1.8.0

What's New

• Tool dependency reporting — check_tool_specs() validates project tools with version checks after environment setup
• dekk <app> doctor — new built-in subcommand to check project tool health and component requirements
• Two-phase install flow — environment setup runs first, then activation + tool checks + build (fixes stale-env timing bug)
• Fail-fast component requires — selected components with missing deps now fail upfront instead of being silently skipped
• Spinner noise filter — Cargo SQLite "database is locked" warnings no longer pollute spinner output
• Styled help output — project help uses bold cyan headers, bold blue sections, and cyan command names
• Top-level dekk doctor — now shows tool dependencies from nearest .dekk.toml after hardware info
