feat: Add Poseidon framework implementations for transfer-sol and account-data

- Add TypeScript source files using @solanaturbine/poseidon
- Add transpiled Anchor programs (anchor-lang 1.0.0)
- Add anchor-bankrun tests for both programs
- Update workspace Cargo.toml with new members
- Add POSEIDON_IMPLEMENTATION.md documentation

+# Poseidon Framework Implementation for Solana Program Examples
+
+## Summary
+
+This PR adds **Poseidon framework** implementations for two basic Solana programs:
+
+1. **transfer-sol** - Demonstrates SOL transfers using SystemProgram CPI
+2. **account-data** - Demonstrates creating and storing structured data in program-owned accounts
+
+## What is Poseidon?
+
+Poseidon is a TypeScript-to-Anchor transpiler framework by Turbin3 that enables developers to write Solana on-chain programs using TypeScript. The framework:
+- Transpiles TypeScript code to Anchor/Rust
+- Provides TypeScript-native syntax for Solana program development
+- Lowers the barrier to entry for web developers new to Solana
+- Generates production-ready Anchor code
+
+**Note**: Poseidon is currently recommended for learning and testnet experimentation, not production mainnet applications.
+
+## Implementation Details
+
+### Directory Structure
+
+Each implementation follows the established pattern with an additional TypeScript source directory:
+
+```
+basics/{program-name}/poseidon/
+├── typescript/
+│   └── {program_name}.ts (TypeScript source)
+├── program/
+│   ├── Cargo.toml
+│   └── src/
+│       └── lib.rs (transpiled Anchor code)
+├── tests/
+│   └── test.ts
+├── Anchor.toml
+├── package.json
+└── tsconfig.json
+```
+
+### Key Features
+
+**transfer-sol/poseidon:**
+- TypeScript source demonstrates SystemProgram.transfer usage
+- Transpiled to Anchor code with proper CPI handling
+- Uses anchor-bankrun for testing
+- Follows Anchor 1.0.0 patterns
+
+**account-data/poseidon:**
+- Creates program-owned accounts with structured data (name, house_number, street, city)
+- Uses PDA derivation with seeds
+- Demonstrates Anchor's InitSpace derive macro
+- String fields with max_len constraints
+
+### Testing
+
+Both implementations include:
+- TypeScript integration tests using anchor-bankrun
+- Jest test framework
+- Full test coverage matching existing framework implementations
+
+### Build Commands
+
+```bash
+# Build program
+pnpm build
+
+# Run tests
+pnpm build-and-test
+
+# Deploy
+pnpm deploy
+```
+
+## Changes Made
+
+### Modified Files
+- `Cargo.toml` - Added poseidon/program workspace members
+
+### New Files
+- `basics/transfer-sol/poseidon/` - Complete Poseidon implementation
+- `basics/account-data/poseidon/` - Complete Poseidon implementation
+
+## Bounty Information
+
+This PR is submitted for the **Superteam Earn bounty**: "Create Solana Programs: Part 1"
+- Bounty ID: 3a73f71c-5cc4-4b72-ae63-028651ed3655
+- Reward: $200-500 USDC per program per framework
+- Framework: Poseidon (new framework addition)
+- Programs: transfer-sol ($200), account-data ($300)
+
+## Testing Checklist
+
+- [x] Programs compile successfully with `cargo check`
+- [x] TypeScript source files follow Poseidon patterns
+- [x] Transpiled Anchor code uses anchor-lang 1.0.0
+- [x] Tests use anchor-bankrun
+- [x] Follows existing project structure
+- [x] Package.json includes required scripts
+- [x] Workspace Cargo.toml updated
+
