- Make reqwest::Client a LazyLock singleton instead of per-call allocation
- Parallelize 3 independent DB queries in get_index_advisor_report with tokio::join!
- Eliminate per-iteration Vec allocation in snapshot FK dependency loop
- Hoist try_local_pg_dump() call in SampleData clone mode to avoid double execution
- Evict stale schema cache entries on write to prevent unbounded memory growth
- Remove unused ValidationReport struct and config_path field
- Rename IndexRecommendationType variants to remove redundant suffix
Four new killer features leveraging AI (Ollama) and PostgreSQL internals:
- Data Validation: describe quality rules in natural language, AI generates
SQL to find violations, run with pass/fail results and sample violations
- Test Data Generator: right-click table to generate realistic FK-aware test
data with AI, preview before inserting in a transaction
- Index Advisor: analyze pg_stat tables + AI recommendations for CREATE/DROP
INDEX with one-click apply
- Data Snapshots: export selected tables to JSON (FK-ordered), restore from
file with optional truncate in a transaction

- Fix SQL injection in data.rs by wrapping get_table_data in READ ONLY transaction
- Fix SQL injection in docker.rs CREATE DATABASE via escape_ident
- Fix command injection in docker.rs by validating pg_version/container_name
and escaping shell-interpolated values
- Fix UTF-8 panic on stderr truncation with char_indices
- Wrap delete_rows in a transaction for atomicity
- Replace .expect() with proper error propagation in lib.rs
- Cache AI settings in AppState to avoid repeated disk reads
- Cap JSONB column discovery at 50 to prevent unbounded queries
- Fix ERD colorMode to respect system theme via useTheme()
- Extract AppState::get_pool() replacing ~19 inline pool patterns
- Extract shared AiSettingsFields component (DRY popover + sheet)
- Make get_connections_path pub(crate) and reuse from docker.rs
- Deduplicate check_docker by delegating to check_docker_internal

Extract shared call_ollama_chat helper from generate_sql to reuse
settings loading and Ollama API call logic. Add two new AI commands:
- explain_sql: explains what a SQL query does in plain language
- fix_sql_error: suggests corrected SQL based on the error and schema
UI additions: "AI Explain" toolbar button, "Explain" and "Fix with AI"
action buttons on query errors, inline explanation display in results.

Greenplum 7 (PG12-based) compatibility:
- Auto-detect GP via version() string, store DbFlavor per connection
- connect returns ConnectResult with version + flavor
- Fix pg_total_relation_size to use c.oid (universal, safer on both PG/GP)
- Branch is_identity column query for GP (lacks the column)
- Branch list_sessions wait_event fields for GP
- Exclude gp_toolkit schema in schema listing, completion, lookup, AI context
- Smart StatusBar version display: GP shows "GP 7.0.0 (PG 12.4)"
- Fix connection list spinner showing on all cards during connect
AI SQL generation (Ollama):
- Add AI settings, model selection, and generate_sql command
- Frontend AI panel with prompt input and SQL output
