Tool & CI updates

[Copilot]

Adds infrastructure for CI/CD tool management: registration of pre-installed tools, environment variable generation, and unified setup automation.

New Commands

Tool Registration

• fcli tool * register - Register existing tool installations (auto-detect from PATH, env vars, or explicit path)
• fcli tool * env - Output environment variables for tool paths in shell/GitHub/Azure/GitLab formats

Tool Installation Enhancement

• fcli tool fcli install --copy-from - Bootstrap fcli from existing installation (Docker multi-stage builds)

New Actions

fortify-setup

Unified CI/CD tool setup with support for:

• Auto-detection of pre-installed tools
• Dynamic installation with signature verification
• Platform-specific tool caching (GitHub Actions, Azure Pipelines, GitLab CI)
• Air-gapped environments (pre-installed tools only)

# Install specific versions with tool cache
fcli action run fortify-setup \
  --use-tool-cache \
  --sc-client-version 24.4.0 \
  --fod-uploader-version latest

# Air-gapped with pre-installed tools
fcli action run fortify-setup \
  --air-gapped \
  --sc-client-version auto \
  --fod-uploader-version auto

ci-vars Enhancement

Extended with tool cache detection for GitHub Actions (RUNNER_TOOL_CACHE), Azure Pipelines (AGENT_TOOLSDIRECTORY), GitLab CI, and Jenkins. Provides global.ci.toolCacheBaseDir and global.ci.toolCacheDirPattern for platform-aware tool installation paths.
