fix: Make 'Saved to:' regex patterns case-insensitive in install workflow

Fixed case-sensitivity bug where regex patterns failed to match output messages
due to case mismatch between 'saved to:' (lowercase in regex) and 'Saved to:'
(uppercase in actual output).

Changes:
- Line 529: Added (?i) flag to config path extraction regex
- Line 668: Added (?i) flag to package path extraction regex

This fixes the issue where 'skill-seekers install --config react' would:
1. Successfully download and save config to disk
2. Output: '📂 Saved to: output/react.json'
3. But fail with '❌ Failed to fetch config' due to regex mismatch

The workflow now correctly continues to Phase 2 (scraping) after fetching config.

Also updated comment on line 528 to reflect actual output format with emoji.

Fixes #236
