feat: implement bounty CRUD, batch operations, and MCP server for Claude Code ( Issue #844)

[Tusharkhadde]

Feature: Bounty Management CLI & Claude Code Skill (MCP)

This PR expands the SolFoundry CLI with full bounty lifecycle management (CRUD), batch operations, and a native Claude Code skill via the Model Context Protocol (MCP). It also resolves critical environment issues and property-mapping bugs found in the existing CLI codebase. #844

🛠️ Key Improvements & Bug Fixes

• Dependency Resolution: Fixed missing tsx and correctly linked the local @solfoundry/sdk to resolve "module not found" errors during development.
• Fixed Property Mapping: Corrected bugs in profile and status commands where incorrect SDK properties (e.g., total_earnings instead of total_earned) were being accessed.
• Type Safety: Fixed TypeScript compilation errors related to private constructors and type casting that prevented the CLI from building.

🚀 New CLI Commands

• Bounty CRUD: Added full support for create, update, and delete commands directly from the terminal.
• Batch Creation: Implemented a batch create <file.json> command for bulk bounty deployment.
• Example Config: Included batch-example.json as a template for batch operations.

🤖 Claude Code Skill (MCP)

• MCP Server Integration: Implemented a JSON-RPC 2.0 server using @modelcontextprotocol/sdk.
• Exposed Tools: list_bounties, get_bounty, create_bounty, and update_bounty are now available natively to Claude Code and other AI agents.

✅ Verification Results

• All 51 unit tests in sdk/cli are passing.
• Verified CLI help menus and command registration.
• Successfully built both sdk and cli packages.
