5e28cbe4bf refactor: modularize root.zig into specialized modules 
Split monolithic root.zig (4200 lines) into 9 focused modules:
- c.zig: centralized @cImport for SQLite
- errors.zig: Error enum and resultToError
- types.zig: OpenFlags, ColumnType, Limit, enums
- database.zig: Database struct with all methods
- statement.zig: Statement struct with bindings/columns
- functions.zig: UDFs, hooks, and C callbacks
- backup.zig: Backup and Blob I/O
- pool.zig: ConnectionPool (thread-safe)
- root.zig: re-exports + tests (~1100 lines)

Total: ~3600 lines (74% reduction in root.zig)
All 47 tests passing.

7229c27c80 Fase 4: Window functions, URI, pragmas y connection pool 
- Window functions: createWindowFunction() con 4 callbacks
  (xStep, xFinal, xValue, xInverse)
- URI connection string: openUri() y openUriAlloc()
  (file:path?mode=ro&cache=shared)
- Pragmas adicionales: setAutoVacuum, setCacheSize,
  setCaseSensitiveLike, setDeferForeignKeys, setLockingMode,
  setQueryOnly, setRecursiveTriggers, setSecureDelete,
  setPageSize, setMaxPageCount, setTempStore, setWalAutoCheckpoint
- Maintenance: vacuum, incrementalVacuum, optimize,
  integrityCheck, quickCheck, walCheckpoint
- ConnectionPool: pool thread-safe con acquire/release

733533ec83 feat(v0.5): Fase 3B - Callbacks avanzados, limits y timestamps 
Implementa todas las funcionalidades restantes de la paridad con go-sqlite3:

Callbacks y Hooks:
- Authorizer callback para control de operaciones SQL
- Pre-update hook con acceso a valores antes/despues del cambio
- Progress handler para interrumpir queries largos
- Busy handler personalizado (custom callback)

APIs adicionales:
- Limits API (getLimit/setLimit) para control de limites SQLite
- Column metadata extendida (columnDatabaseName, columnTableName, columnOriginName)
- Expanded SQL (stmt.expandedSql)
- Timestamp binding (bindTimestamp, bindCurrentTime) con formato ISO8601

Build:
- Habilitado SQLITE_ENABLE_PREUPDATE_HOOK en build.zig
- Definido @cDefine en @cImport para exponer APIs opcionales

Tests:
- Tests para authorizer, progress handler, limits, expanded SQL
- Tests para column metadata y pre-update hook
- Tests para timestamp binding

Documentacion actualizada con todos los nuevos APIs y ejemplos.
