fix(ci): sudo for ripgrep + submodule clone auth notes

[POWERFULMOVES]

Summary

• Add sudo to apt-get install ripgrep in chit-contract verify job (self-hosted runner is non-root)

Root Cause

chit-contract.yml verify job runs on [self-hosted, ai-lab] where the runner process is non-root. apt-get requires sudo on these runners.

Systemic Notes

Multiple workflows use submodules: recursive which fails on private submodules (PMOVES-transcribe-and-fetch) without a PAT token. This is tracked separately — affects PRs #633, #642 Audit Gate failures.

Affected PRs

• feat(codex): archon-hirag stability, CHIT encryption, hyperdimensions topology #633 (verify failure) — will pass after this merge
• ci: harden workflows and add integration branch triggers #642 (verify failure) — will pass after this merge
• feat(mesh): v2 namespace publishing + docs #644 (verify pending) — will pass after this merge
