feat: implement latest oca-sdk-rs

Replace oca-bundle-semantics and oca-ast-semantics (external) with
oca-sdk-rs (local) to consolidate dependencies and leverage the
comprehensive API already available in oca-sdk-rs v2.0.0-rc.5.

This migration maintains backward compatibility while improving
dependency management and reducing external dependencies.

Update README with:
- Installation instructions
- Feature overview
- Multiple usage examples covering:
- Build process explanation
- Migration notes from oca-bundle-semantics
- Available overlay types reference
- Dependencies information

Completely rewrite the WASM bindings to remove OCABox and Overlay remnants,
focusing on OCABundle parsing and manipulation:

New Features:
- parseOCABundle() - parse JSON to OCABundle object
- validateBundle() - validate OCABundle (placeholder for now)
- bundleToJSON() - convert OCABundle to JSON string
- getBundleDigest() - extract bundle digest (SAID)
- getBundleVersion() - extract bundle version
- getBundleType() - extract bundle type
- getBundleClassification() - extract classification
- getBundleAttributes() - get all attributes
- getBundleFlaggedAttributes() - get all flagged attributes
- hasOverlays() - check if bundle has overlays
- getOverlayCount() - get number of overlays
- getOverlayNames() - get all overlay names

OCABundle Creation:
- createEmptyBundle() - create empty bundle with classification
- createBundleWithAttributes() - create bundle with attributes
- createBundleWithOverlay() - create bundle with overlay
- addAttributeToBundle() - add attribute to bundle
- removeAttributeFromBundle() - remove attribute from bundle
- addOverlayToBundle() - add overlay to bundle
- removeOverlayFromBundle() - remove overlay from bundle

-## JS WASM bindings
+## JavaScript WASM Bindings
 
-### Build
+This package provides JavaScript bindings for OCA (Overlays Capture
+Architecture) using WebAssembly.
 
-Building local NPM package  
-in `js/wasm` directory:  
-`bash build-pkg.sh`  
+It expose oca-sdk-rs into Java Scritp Ecosystem.
 
-### Run [tests](example/test)
+### Features
 
-Go to js/example directory and install dependencies  
+- ✅ **Load and validate OCA bundles** from JSON
+- ✅ **Build OCA bundles** with attributes, overlays, and metadata
+- ✅ **Parse and generate AST** (Abstract Syntax Tree)
+- ✅ **Attribute validation** with overlay definitions
+- ✅ **Multiple attribute types**: Text, Numeric, Boolean, DateTime, Binary, Reference, Array, etc.
+- ✅ **Overlay support**: Meta, Label, Format, Information, CharacterEncoding, Unit, Conformances, EntryCodes, Entry, Link, and more
+- ✅ **Framing support** for ontology alignment
 
+### Installation
+
+```bash
+# Install locally
+cd oca-bindings/js
+yarn install
+
+# Or use npm
+npm install
+
+# Build the WASM package
+cd wasm
+bash build-pkg.sh
+
+# The package will be built in the `pkg` directory
+```
+
+### Usage Examples
+
+#### Basic OCA Bundle Creation
+
+```javascript
+const { OCABox, Attribute, create_nested_attr_type_from_js } = require('oca.js');
+
+// Create a new OCA bundle
+const oca = new OCABox()
+  .addClassification("GICS:35102020")
+  .generateBundle();
+
+console.log('OCA Bundle:', oca);
+```
+
+#### Adding Attributes
+
+```javascript
+const numericType = create_nested_attr_type_from_js("Numeric");
+const oca = new OCABox()
+  .addClassification("GICS:35102020")
+  .addAttribute(
+    new Attribute("age")
+      .setAttributeType(numericType)
+      .setLabel({ eng: "Age", pol: "Wiek" })
+      .setFormat("0-120")
+  )
+  .generateBundle();
 ```
+
+#### Working with Multiple Languages
+
+```javascript
+const oca = new OCABox()
+  .addClassification("GICS:35102020")
+  .addMeta("name", {
+    eng: "Driving Licence",
+    pol: "Prawo Jazdy"
+  })
+  .addMeta("description", {
+    eng: "DL desc",
+    pol: "PJ desc"
+  })
+  .generateBundle();
+```
+
+#### Parsing Existing OCA Bundles
+
+```javascript
+const oca_bundle_json = require('./path/to/oca.json');
+const oca_box = new OCABox()
+  .load(oca_bundle_json)
+  .addClassification("test_classification");
+
+const attributes = oca_box.attributes();
+const meta = oca_box.meta();
+
+console.log('Attributes:', attributes);
+console.log('Metadata:', meta);
+```
+
+#### Generating AST
+
+```javascript
+const oca_box = new OCABox().load(oca_bundle_json);
+const ast = oca_box.toAST();
+
+console.log('AST Version:', ast.version);
+console.log('Commands:', ast.commands);
+```
+
+#### Attribute Types Support
+
+```javascript
+const textType = create_nested_attr_type_from_js("Text");
+const numericType = create_nested_attr_type_from_js("Numeric");
+const booleanType = create_nested_attr_type_from_js("Boolean");
+const dateTimeType = create_nested_attr_type_from_js("DateTime");
+const binaryType = create_nested_attr_type_from_js("Binary");
+
+// Create array types
+const arrayType = create_nested_attr_type_from_js(["Text"]);
+const arrayTypeWithRef = create_nested_attr_type_from_js(["refs:ABC123"]);
+
+// Reference to another bundle
+const refType = create_nested_attr_type_from_js("refs:EF5ERATRBBN_ewEo9buQbznirhBmvrSSC0O2GIR4Gbfs");
+```
+
+#### Overlays
+
+The OCA bundle supports various overlay types:
+
+```javascript
+const oca = new OCABox()
+  .addClassification("GICS:35102020")
+  .addMeta("name", { eng: "Name" })
+  .addMeta("description", { eng: "Description" })
+  .addAttribute(
+    new Attribute("attr_name")
+      .setAttributeType(numericType)
+      .setLabel({ eng: "Name: " })
+      .setInformation({ eng: "En info" })
+      .setEntries({
+        o1: { eng: "Option 1", pol: "Opcja 1" },
+        o2: { eng: "Option 2", pol: "Opcja 2" }
+      })
+      .setLinks({ "target_bundle_said": "name" })
+      .setFramings({
+        frame_id: "SNOMEDCT",
+        frame_label: "Clinical Terms",
+        frame_location: "https://bioportal.bioontology.org/ontologies/SNOMEDCT",
+        frame_version: "2023AA"
+      }, {
+        "http://purl.bioontology.org/ontology/snomedct/703503000": {
+          predicate_id: "skos:exactMatch",
+          framing_justification: "semapv:ManualMappingCuration",
+        }
+      })
+  )
+  .generateBundle();
+```
+
+### Validation
+
+```javascript
+const { Validator } = require('oca.js');
+const oca = new OCABox().addClassification("GICS:35102020").generateBundle();
+const validator = new Validator();
+
+const result = validator.validate(oca);
+console.log('Valid:', result.success);
+if (!result.success) {
+  console.log('Errors:', result.errors);
+}
+```
+
+### TypeScript Support
+
+The bindings include TypeScript definitions. You can use them in TypeScript projects:
+
+```typescript
+import { OCABox, Attribute, create_nested_attr_type_from_js } from 'oca.js';
+
+const numericType = create_nested_attr_type_from_js("Numeric");
+const oca = new OCABox()
+  .addClassification("GICS:35102020")
+  .addAttribute(
+    new Attribute("age")
+      .setAttributeType(numericType)
+      .setLabel({ eng: "Age" })
+  )
+  .generateBundle();
+```
+
+### Running Tests
+
+```bash
+# Install dependencies
+cd example
 yarn install
+# or
+npm install
+
+# Run all tests
 yarn test
+# or
+npm test
+
+# Run a specific test
+yarn test parsing-oca.test.ts
 ```
+
+### Build Process
+
+The build process uses `wasm-bindgen` to compile Rust code to JavaScript:
+
+1. **Rust compilation**: `cargo build --target wasm32-unknown-unknown --release`
+2. **WASM generation**: `wasm-bindgen` converts .wasm to JS bindings
+3. **Package generation**: Creates npm package in `pkg/` directory
+4. **TypeScript definitions**: Automatically generated from Rust code
