Plan: Apply escapeIdentifier consistently across all methods

Based on the feedback, I need to apply the escapeIdentifier function to all SQL queries that use schema and table names, not just the iterator() method.

• Understand current implementation and identify all methods that need updates
• Apply escapeIdentifier to get() method (line 80)
• Apply escapeIdentifier to getMany() method (line 87)
• Apply escapeIdentifier to set() method (line 96)
• Apply escapeIdentifier to setMany() method (line 110)
• Apply escapeIdentifier to delete() method (lines 118-119)
• Apply escapeIdentifier to deleteMany() method (lines 131-132)
• Apply escapeIdentifier to clear() method (line 144)
• Apply escapeIdentifier to has() method (line 199)
• Apply escapeIdentifier to constructor's createTable (lines 48, 51)
• Build and lint the code
• Run targeted tests to validate changes
• Run full test suite
• Code review
• Security check with CodeQL
