Major improvements to docs:create UX for both Claude Code and external tool integration:
**New `docs` CLI command:**
- Add scripts/docs-cli.js - main CLI with subcommand routing
- Add bin field to package.json for `docs` command
- Usage: `docs create` and `docs edit` (cleaner than yarn commands)
**Smart piping detection:**
- Auto-detect when stdout is piped (\!process.stdout.isTTY)
- When piping: automatically output prompt text (no flag needed)
- When interactive: output prompt file path
- --print-prompt flag now optional (auto-enabled when piping)
**Updated help text:**
- Show `docs create` syntax first, yarn as alternative
- Simplify examples with new CLI
- Document smart piping behavior
- Focus on two main workflows: Claude Code vs external agents
**Usage examples:**
# Inside Claude Code - automatic execution
docs create drafts/new-feature.md
# Pipe to external AI - prompt auto-detected
docs create FILE --products X | claude -p
docs create FILE --products X | copilot -p
# Pipe from stdin
echo 'content' | docs create --products X | claude -p
Benefits:
- Cleaner syntax (no yarn --silent needed)
- No manual --print-prompt flag when piping
- Consistent with industry tools (git, npm, etc.)
- Backward compatible with yarn commands
