refactor: merge deps into hooks provisioning pipeline

[stepandel]

Summary

• Eliminates the parallel deps pipeline (phase_deps_root + phase_deps_post) by merging dep scripts into postProvisionHooks with runAs metadata
• Gives brave-search a real postInstallScript instead of a hardcoded special case in provisioner-config.ts
• Adds optional runAs field to hook entries, defaulting to "ubuntu" in the bash template
• Cleans up dead braveApiKey/tools fields from config-generator.ts

Test plan

• pnpm build — all packages compile
• pnpm test — all 344 tests pass
• Verify generated cloud-init script has no phase_deps_root/phase_deps_post
• Verify postProvisionHooks contains dep:* entries with correct runAs
• Verify brave-search config is no longer in configSetCommands

🤖 Generated with Claude Code

Summary by CodeRabbit

• New Features

  • Added runAs field to provisioning hooks for per-hook user execution control (root or ubuntu).

• Improvements

  • Brave Search configuration is now handled automatically via dependency post-install scripts.
  • Simplified configuration by integrating dependency hooks into postProvisionHooks.
  • Removed unnecessary public configuration fields for cleaner interfaces.
