ci: post-merge fixes — Vercel deploy cwd, try-runtime snapshots, gittensor indexer

[unarbos]

Summary

Consolidated fixes for the CI breakages surfaced by the first post-merge runs on main:

• Deploy Docs failed (ENOENT): vercel build ran from website/, but the Vercel project's root directory (website/apps/bittensor-website) is resolved against the CLI's cwd, doubling the path. Dropped working-directory: website from the staging deploy (deploy-docs.yml) and the production promotion (watch-mainnet-release.yml).
• All three try-runtime snapshot jobs failed: in refresh-mainnet-snapshot.yml, create-snapshot --uri <ws> <name>.snap fails because --uri is variadic and swallows the trailing snapshot path ("not a valid WS(S) url"). Moved the positional path before --uri. (The mainnet clone snapshot job in the same workflow succeeded and already published its artifact.)
• ai-review-index-gittensor fails every scheduled run: the pinned gittensor commit declares requires-python >=3.12; bumped the job's Python from 3.11 to 3.12 (pin unchanged).

Related cleanup handled outside this PR:

• ai-review: handle PRs over the 300-file diff cap in prefetch #2845 closed as superseded — its prefetch.sh large-diff fallback and cargo-audit rework already landed on main via bittensor-core: one Rust core (keys, keyfiles, timelock, codec, RFC-0078 digest, Ledger) under a thin Python SDK #2846.
• Benchmark weight drift needs no action — main already carries the reference-runner weights (5fc21c1).

Test plan

• After merge, workflow_dispatch Deploy Docs → staging deploy succeeds
• After merge, workflow_dispatch Refresh Mainnet Snapshot → all four snapshot artifacts publish
• Next scheduled ai-review-index-gittensor run installs and indexes cleanly

🛡️ AI Review — Skeptic (security review)

VERDICT: SAFE

MEDIUM scrutiny by account age, mitigated by repository write access and substantial contributions; no Gittensor association. CI/deployment hotfix targets main.

Static review found the workflow-only changes consistent with the documented failures. Since the prior SAFE verdict, the only addition changes the indexer from Python 3.11 to the pinned Gittensor dependency’s required Python 3.12. No review-policy files, runtime code, dependencies, permissions, triggers, or secret handling are changed.

Findings

No findings.

Conclusion

The patch remains small and mechanical, with no apparent security vulnerability or malicious behavior.

🔍 AI Review — Auditor (domain review)

VERDICT: 👍

UNKNOWN Gittensor association; established high-volume contributor with repository write access and substantial merged work.

This deployment-only CI hotfix appropriately targets main. The workflow changes consistently address the documented Vercel cwd issue, variadic --uri parsing, and gittensor's Python requirement.

The overlap with broad monorepo PR #2841 is incidental rather than duplicate work. Static inspection was sufficient; runtime code, dependencies, and spec_version are unaffected.

Findings

No findings.

Conclusion

The changes are minimal, internally consistent, and match the reported CI failures. Ready to merge.
