feat: Implement all analysis commands with daemon routing

Add complete implementation for all stub commands:
- Symbol operations (list, get, create, rename, delete)
- Type operations (list, get, create, apply)
- Comment operations (list, get, set, delete)
- Graph operations (calls, callers, callees, export)
- Find operations (string, bytes, function, calls, crypto, interesting)
- Diff operations (programs, functions)
- Patch operations (bytes, nop, export)
- Script operations (list, run, python inline)
- Disasm command (disassembly at address)
- Batch operations (execute commands from file)
- Stats command (program statistics)

Fix critical routing bug where new commands fell through to
"Command not yet implemented" instead of being routed to daemon.

Add ExecuteCli IPC command for forwarding CLI commands through daemon.
Add comprehensive integration tests for all new commands.
