Subject: [PATCH] Fix missing files detection - add 'was not found at' pattern

The intelligent recovery system wasn't detecting missing .ibd files because
MariaDB/MySQL error format uses 'was not found at' instead of 'missing'.

Changes:
- Added 'was not found at' pattern to grep searches (3 locations)
- Enhanced tablespace extraction to parse './db/table.ibd' format
- Extracts database/table from error: 'Tablespace N was not found at ./db/table.ibd'
- Falls back to quoted tablespace name extraction if new pattern doesn't match

Now when script detects missing .ibd files it will:
- Show DIAGNOSIS: Missing or unopenable tablespace files
- List exact missing tables with database names
- Provide copy-paste ready cp commands
- Show all recovery options instead of generic troubleshooting
