Fourth of five PRs that re-ship #14665 on current main, ordered from lowest to highest risk. Branched off main, independent of the others.

What's in it

sdk error-handling fixes, with a patch changeset, so merging this publishes an sdk version.

• Storage uploads: tus doesn't await onSuccess, so a polling failure became an unhandled rejection and start() never settled. Polling results now go to resolve/reject.
• Aborted uploads: the abort check sat inside the polling try, so the abort error was caught and retried every 3s for up to an hour. It's checked before the try.
• StorageNodeSelector: if the first node list fetch failed, selection ordered the bootstrap nodes and kept that order after a later fetch succeeded. The ordering is now dropped when the list refreshes, and selection holds a local reference so a refresh mid-selection can't swap the list out from under it. New test covers it.
• Request signature middleware: after logout or a signing failure it kept attaching the previous user's cached signature. The cache is cleared on error. New test covers it.
• SolanaRelayWalletAdapter.connect(): connecting stayed true forever if getFeePayer threw.
• SolanaRelay.relay(): a non-JSON or null error body replaced the real ResponseError with a parse error.
• SolanaClient.buildTransaction(): the 1.5x priority multiplier can produce a fractional fee, and setComputeUnitPrice throws on it when converting to BigInt. The fee is rounded. New test covers it.
• ChatsApi: a rejected public key lookup was cached, which broke create/invite for that user until reload. Websocket handler rejections were unhandled; they're now logged.

Why this tier

Published package, and uploads now reject in cases where they used to hang. Callers that never handled a rejection from upload.start() will now see one.

Dropped from #14665

• The constructor-time updateAvailableStorageNodes unhandled rejection: main now fetches the node list lazily with its own catch.
• isNodeHealthy getting the sdk logger: skipped here to keep this PR independent of tier 1, which moves the function.

Verified

• tsc and eslint (changed files): clean.
• sdk vitest: all files pass, including the new tests.

Not verified

No end-to-end upload against a real node.
