fix(cli): fix generated Go MCP server run and doc (#104)

This fixes the kmcp run command for mcp servers generated with kmcp init
go and updates the generated README with the accurate file paths

### Before these change
kmcp run results in the following error
```
Running server directly: go run main.go
Server is running and waiting for MCP protocol input on stdin...
Press Ctrl+C to stop the server
stat main.go: no such file or directory
Error: exit status 1
```
### After these changes
- Docs reference the proper file paths
- `kmcp run` uses the right path to main.go to start the server
- The mcp inspector server config uses the right path to main.go
