Implement non-interactive logic: use AI suggestions regardless of confidence, provide defaults on failure

[shayonpal]

Description

Implement the non-interactive execution logic when --popclip-mode flag is set. The script should never prompt for user input and should handle all scenarios automatically.

Acceptance Criteria

• When --popclip-mode is set, always use AI suggestions regardless of confidence level
• If AI categorization fails completely, implement sensible fallback defaults
• Remove all input() calls when in PopClip mode
• Provide appropriate exit codes for success/failure scenarios
• Return status messages suitable for PopClip feedback

Context

This is the core implementation work for PopClip integration, building on the flag added in issue #14. This will make the script fully autonomous when triggered from PopClip.

Technical Implementation

Default Fallback Strategy

When AI fails in PopClip mode:

• Collection: "General" or analyze content for keywords
• Name: First 50 characters of content, cleaned up
• Keyword: Generate from content (e.g., first word + timestamp)
• Description: "Snippet created via PopClip"

Error Handling

• Never use input() when --popclip-mode is True
• Log errors but continue with defaults
• Exit with appropriate codes (0 for success, 1 for failure)

Notification Changes

• Suppress or modify macOS notifications in PopClip mode
• Consider returning status via stdout for PopClip to display

Dependencies

• Requires issue Add --popclip-mode flag to add_alfred_snippet.py for non-interactive execution #14 to be completed first (--popclip-mode flag)

Priority

Medium (P2) - Critical functionality for PopClip integration
