feat: implement OPTIMAL npx solution following 2024 best practices, bump to 0.1.9

Based on comprehensive research of successful scoped packages:

BEFORE (suboptimal):
- Bin: {"ccstatus": "src/context-status.js"}
- Usage: npx -p @this-dot/claude-code-context-status-line ccstatus

AFTER (optimal):
- Bin: "src/context-status.js" (string format)
- Usage: npx @this-dot/claude-code-context-status-line (direct!)

Key improvements:
✅ String bin format auto-creates bin name from package name (without scope)
✅ Direct npx execution without -p flag (cleaner UX)
✅ Follows 2024 working example pattern: @myscope/mod-hook01 → npx @myscope/mod-hook01
✅ Tested and confirmed working locally

Research shows successful scoped packages use bin names matching unscoped package names.
