Unable to auto attach to an already-running Kubo daemon

[jexjws]

• OS: Linux (Arch Linux x86_64, Kernel 7.2 / Flatpak / native)
• Version of IPFS Desktop: 0.50.0 / 0.50.1

Describe the bug
When a local Kubo daemon is already running, IPFS Desktop should detect and attach to it seamlessly. Currently, this fails due to two sequential issues:

1. Gateway probe false positive (PR fix: probe HTTP gateways independently of the RPC API #3217): checkIfAddrIsDaemon() sends an RPC POST /api/v0/refs... to the gateway port (which returns 404), triggering a false "Ports are busy" prompt instead of recognizing the node.
2. Crash on modern multiaddrs (PR fix: replace ipfs-http-client with kubo-rpc-client #3034): During handshake (id()), legacy multiaddr@10.0.1 fails on modern Kubo addresses (e.g. /tls/, /quic-v1/ from AutoTLS) with Error: no protocol with name: tls, aborting startup and leaving WebUI failing at 127.0.0.1:5001.

To Reproduce
Steps to reproduce the behavior:

1. Start an external Kubo daemon (v0.33+ / 0.43+) on custom ports (e.g. API 5003, Gateway 8084) with "AutoTLS": { "Enabled": true }.
2. Point IPFS Desktop to this repository (via IPFS_PATH or ~/.ipfs).
3. Launch IPFS Desktop.
4. Observe the "Ports are busy" modal dialog:

   "The ports 5003 and 8084 are not available. Do you want to use 5004 and 8085 instead?"

5. With PR fix: probe HTTP gateways independently of the RPC API #3217 applied, observe combined.log:
   error: [ipfsd] start daemon Error: no protocol with name: tls
6. Notice WebUI opens but fails to connect, falling back to http://127.0.0.1:5001.

Expected behavior

• IPFS Desktop recognizes the ports belong to a running daemon ([daemon] ports busy by a daemon).
• It attaches to the existing daemon without spawning a duplicate process or prompting to change ports.
• It parses node addresses without crashing on modern protocols.
• WebUI automatically launches with ?api=/ip4/127.0.0.1/tcp/<API_PORT>.
