planetazuzu 5d7a6500fe refactor: Fase 1 - Clean Architecture, refactorización modular y eliminación de duplicidades

- ✅ Ticket 1.1: Estructura Clean Architecture en backend
- ✅ Ticket 1.2: Schemas Zod compartidos
- ✅ Ticket 1.3: Refactorización drugs.ts (1362 → 8 archivos modulares)
- ✅ Ticket 1.4: Refactorización procedures.ts (3583 → 6 archivos modulares)
- ✅ Ticket 1.5: Eliminación de duplicidades (~50 líneas)

Cambios principales:
- Creada estructura Clean Architecture en backend/src/
- Schemas Zod compartidos en backend/src/shared/schemas/
- Refactorización modular de drugs y procedures
- Utilidades genéricas en src/utils/ (filter, validation)
- Eliminados scripts obsoletos y documentación antigua
- Corregidos errores: QueryClient, import test-error-handling
- Build verificado y funcionando correctamente

CRC32 Stream

crc32-stream is a streaming CRC32 checksumer. It uses the crc module behind the scenes to reliably handle binary data and fancy character sets. Data is passed through untouched.

Install

npm install crc32-stream --save

You can also use npm install https://github.com/archiverjs/node-crc32-stream/archive/master.tar.gz to test upcoming versions.

Usage

CRC32Stream

Inherits Transform Stream options and methods.

const {CRC32Stream} = require('crc32-stream');

const source = fs.createReadStream('file.txt');
const checksum = new CRC32Stream();

checksum.on('end', function(err) {
  // do something with checksum.digest() here
});

// either pipe it
source.pipe(checksum);

// or write it
checksum.write('string');
checksum.end();

DeflateCRC32Stream

Inherits zlib.DeflateRaw options and methods.

const {DeflateCRC32Stream} = require('crc32-stream');

const source = fs.createReadStream('file.txt');
const checksum = new DeflateCRC32Stream();

checksum.on('end', function(err) {
  // do something with checksum.digest() here
});

// either pipe it
source.pipe(checksum);

// or write it
checksum.write('string');
checksum.end();

Instance API

digest()

Returns the checksum digest in unsigned form.

hex()

Returns the hexadecimal representation of the checksum digest. (ie E81722F0)

size(compressed)

Returns the raw size/length of passed-through data.

If compressed is true, it returns compressed length instead. (DeflateCRC32Stream)
