Fix PR #25 Review: All AI code reviewer feedback addressed

This commit addresses all recommendations from CodeRabbit, Gemini Code Assist,
and Copilot for PR #25 (FTS security and code quality improvements).

Critical Security Fixes:
- MCP_Thread.cpp: Rollback fts_path on reset failure to keep config consistent
- MySQL_FTS.cpp: Add escape_mysql_identifier() for MySQL query identifier escaping
- MySQL_FTS.cpp: Add unique hash-based fallback to sanitize_name() for empty strings
- MySQL_FTS.cpp: Add where_clause validation to block dangerous SQL patterns

Memory Safety Fixes:
- MySQL_FTS.cpp: Fix indexes_result memory leak on early return in search()
- MySQL_FTS.h: Delete copy/move operations to prevent accidental resource duplication

Thread Safety Documentation:
- MySQL_Tool_Handler.cpp: Add comment explaining FTS lock design rationale

Test Script Improvements:
- test_mcp_fts.sh: Add curl timeouts (5s connect, 30s max)
- test_mcp_fts.sh: Remove unused delete_response variable
- test_mcp_fts_detailed.sh: Make cleanup tolerant of non-existent indexes

Build Fixes:
- Makefile: Fix EXCLUDE_TRACKING_VARAIABLES typo to EXCLUDE_TRACKING_VARIABLES
- vector_db_performance-t.cpp: Fix printf format specifiers to %lld with cast

Schema Fixes:
- Query_Tool_Handler.cpp: Change fts_index_table columns schema from string to array

Code Cleanup:
- MySQL_Tool_Handler.cpp: Remove all remaining debug fprintf statements (34 lines)
- Documentation: Change "Full Text" to "Full-Text" (hyphenated)

Total: ~50 fixes across 10 files

Fix PR #21 review: Security, memory safety, thread safety, and code cleanup

Security fixes:
- Add escape_identifier() helper for proper SQLite identifier escaping
- Replace sanitize_name() with allowlist validation (ASCII letters, digits, underscore only)
- Fix MATCH clause FTS5 operator injection by wrapping query in double quotes
- Apply escape_identifier() to all DDL statements (CREATE, DROP, triggers)

Memory safety fixes:
- Replace VLA with std::vector in MySQL_FTS::init(), add delete on error path
- Fix memory leak: free error string before return in list_indexes()
- Fix reindex_json["error"] potential exception using .value() with default

Thread safety fixes:
- reinit_fts(): Add mutex lock around pointer swap
- reset_fts_path(): Move blocking init() outside lock, only swap pointer under lock

Code cleanup:
- Remove 7 debug fprintf statements from Query_Tool_Handler.cpp
- Remove unused #include <memory> from MySQL_FTS.h

Test script security fixes:
- Use MYSQL_PWD environment variable instead of -p"..." for password
- Add escape_sql() function and apply to INSERT statement
- Fix CURL_OPTS quoting: ${CURL_OPTS:+"${CURL_OPTS}"}
- Remove unused FTS_INDEX_NAME and SEARCH_QUERIES variables

Documentation fixes:
- Fix bare URL to markdown link format
- Add code block language identifiers (text, bash)

Add full-text search (FTS) tools to MCP query server

Implement BM25-ranked full-text search capability for MySQL/MariaDB tables using SQLite-based external FTS index.

Changes:
- Add MySQL_FTS class for managing SQLite FTS indexes
- Add FTS tools: fts_index_table, fts_search, fts_reindex, fts_delete_index, fts_list_indexes, fts_rebuild_all
- Add thread-safe FTS lifecycle management with fts_lock mutex
- Add reset_fts_path() for runtime FTS database path configuration
- Add comprehensive FTS test scripts (test_mcp_fts.sh, test_mcp_fts_detailed.sh)
