feat: generate JSON schemas for all manifest versions

Browse source 
Updated build script to generate JSON schemas for all historical manifest
versions (v0.1, v0.2, v0.3) in addition to the latest version.

Changes:
- Generate mcpb-manifest-v0.1.schema.json
- Generate mcpb-manifest-v0.2.schema.json
- Generate mcpb-manifest-v0.3.schema.json
- Generate mcpb-manifest-latest.schema.json
- Keep mcpb-manifest.schema.json as alias for latest
- All schemas generated to both dist/ and schemas/ directories
- Added exports in package.json for all versioned schemas

Benefits:
- Tools can validate against specific manifest versions
- Backwards compatibility for all historical versions
- Latest schema always available at predictable path
- JSON schema files match the Zod schema versions

Usage:
import manifestSchema from '@anthropic-ai/mcpb/mcpb-manifest-v0.2.schema.json'
import latestSchema from '@anthropic-ai/mcpb/mcpb-manifest-latest.schema.json'
