Release v1.1.0 - Add WebLN API support for Lightning wallet integration

- Add window.webln API for web app Lightning wallet integration
- Implement webln.enable(), getInfo(), sendPayment(), makeInvoice() methods
- Add WebLN permission prompts with proper amount display for payments
- Dispatch webln:ready and webln:enabled events per WebLN standard
- Add NWC client caching for persistent wallet connections
- Implement inline BOLT11 invoice amount parsing
- Always prompt for sendPayment (security-critical, irreversible)
- Add signMessage/verifyMessage stubs that return "not supported"
- Fix response handling for undefined returns in content script
