v0.3.0: Fix daemon, in-module WebUI only, remove standalone server

Daemon fixes:
- Fixed MODDIR detection (removed readlink -f, use directory probe)
- Removed all 'local' keyword usage (Android sh compatibility)
- Removed duplicate network blocklist install
- Removed reference to deleted webui.sh
- Default log level now INFO (was WARN, hiding startup messages)

WebUI:
- Removed standalone webui.sh HTTP server
- WebUI is now in-module only (webroot/index.html via KernelSU manager)
- Uses ksu.exec() API — no server process needed
- Tap module card in KernelSU to open dashboard

Cleanup:
- Removed stealth.sh
- Removed WEBUI_ENABLED/WEBUI_PORT config (not needed for in-module)
- Removed webui CLI command
- Bumped to v0.3.0
