Bug: multi-platform install race in installVerbatimSkills() deletes source before sibling platforms copy

[alexeyv]

Description

In _config-driven.js, installVerbatimSkills() (around lines 693–702), for records where install_to_bmad === 'false', the cleanup loop unconditionally deletes the source directory after installation. When multiple skill_format platforms (e.g., Kiro and Ona) are installed in the same CLI invocation, the first platform to run this loop deletes the source; the second platform finds nothing to copy and silently installs 0 verbatim skills for those entries.

Steps to Reproduce

1. Install BMAD with two or more skill_format platforms selected simultaneously (e.g., --tools kiro,ona)
2. Include a skill with install_to_bmad: 'false'
3. Observe that only the first platform receives the verbatim skill files

Suggested Fix

// Guard against source already removed by prior platform
if (await fs.pathExists(sourceDir)) {
  await fs.remove(sourceDir);
}

Source

Found during PR review of #1968. Not specific to that PR — this is a pre-existing issue in the shared installer logic.
