czlonkowski b12a927a10 fix: harden signal handlers with robust container detection (Issue #277)
Production-ready improvements based on comprehensive code review:

Critical Fixes:
- Robust container detection: Checks multiple env vars (IS_DOCKER, IS_CONTAINER)
  with flexible formats (true/1/yes) and filesystem markers (/.dockerenv,
  /run/.containerenv) for Docker, Kubernetes, Podman, containerd support
- Fixed redundant exit calls: Removed immediate exit, use 1000ms timeout for
  graceful shutdown allowing cleanup to complete
- Added error handling for stdin registration with try-catch
- Added shutdown trigger logging (SIGTERM/SIGINT/SIGHUP/STDIN_END/STDIN_CLOSE)

Improvements:
- Increased timeout from 500ms to 1000ms for slower systems
- Added null safety for stdin operations
- Enhanced documentation explaining behavior in different environments
- More descriptive variable names (isDocker → isContainer)

Testing:
- Supports Docker, Kubernetes, Podman, and other container runtimes
- Graceful fallback if container detection fails
- Works in Claude Desktop, containers, and manual execution

Code Review: Approved by code-reviewer agent
All critical and warning issues addressed
