fix(handleFileUpload): reliably pin and announce uploaded directory CID

[akhileshthite]

When uploading large files via handleFileUpload, the CID is generated locally but never shows up on the public DHT (IPFS Checker reports “0 working providers”).

What we tried

• After unixfs.addAll(), we now
  • Pin the root CID (node.pins.add(rootCid))
  • Manually advertise it (await node.routing.provide(rootCid))

Console:

Pinned root CID: bafybeidthg7n5lg67eawgyxtliftty2aeebs3a4fhw7wcbf2trlz2f7iem
Pinned root CID: bafkreibdhnynbrqiihdwcauqwywx4a7kkggw2ixnoa6yuhehlcz5d5ylfa
Provided CID on DHT: bafybeidthg7n5lg67eawgyxtliftty2aeebs3a4fhw7wcbf2trlz2f7iem

async function handleFileUpload(request, sendResponse) {

libp2p: https://github.com/p2plabsxyz/peersky-browser/blob/fix/enable-dht-provider/src/protocols/helia/libp2p.js

Current behavior:

Despite those calls, the checker still reports zero providers for the CID:
Http gateway: https://bafybeidthg7n5lg67eawgyxtliftty2aeebs3a4fhw7wcbf2trlz2f7iem.ipfs.dweb.link/

IPFS check: https://check.ipfs.network/?cid=bafybeidthg7n5lg67eawgyxtliftty2aeebs3a4fhw7wcbf2trlz2f7iem

❌ Found 0 working providers (out of 4 provider records sampled from Amino DHT and IPNI) that could be connected to and had the CID available over Bitswap:

Based on the results you shared from IPFS Check, it appears that the CID is successfully advertised to the DHT, but that the node providing is either offline or unreachable because it's behind NAT. Currently, NAT traversal is only supported in js-libp2p (used by Helia) by the webrtc network transport.

From the looks of it, your Helia nodes are only listening on TCP and WS. My recommendation would be to add a webrtc listener as follows: https://github.com/ipfs/helia/blob/313e2c10a71c4f42533c3f077c6720563dd09ce5/packages/helia/src/utils/libp2p-defaults.browser.ts#L46-L51

But if you are running these Helia nodes behind NAT, you are likely to experience such problems, because NAT traversal fails on some networks.
