docs: daily update 2026-08-06 (release v4.191.0)

[deco-cms]

Automated daily docs review triggered by the studio.released webhook for v4.191.0 (previous: v4.190.4).

Note: This PR is stacked on top of #5790 (docs/auto-update-2026-08-06-release-4.188.0), the most recently opened docs auto-update PR at the time of this run. It should be merged after #5790 to avoid conflicts.

Commits covered (range v4.190.4...v4.191.0)

• 5329b7cbc feat(sandbox): tenant warm pools — pods already running the dev server (feat(sandbox): tenant warm pools — pods already running the dev server #5830) — warrants docs update, covered below.
• 148aeeda6 feat(scripts): add manual release fallback for Actions outages (feat(scripts): add manual release fallback for Actions outages #5832) — skipped: internal release-tooling script (scripts/manual-release.sh), no user-facing Studio behavior.
• 16c5aa501 [chore]: bump homebrew cask to 4.190.4 — skipped: bot version-bump commit.
• b1b3a18ef [release]: bump changed workspace versions — skipped: release bump, version-only diff.

Files changed

• en/studio/self-hosting/deploy/kubernetes.mdx — added a new Tenant warm pools section (under Sandbox configuration, after the generic Warm pool section) documenting: the tenantPools chart values entry and its -<envName> naming rule, the STUDIO_SANDBOX_TENANT_POOLS Studio-side JSON env var schema (name, orgId, repo, connectionId, branch, workload), the optional GITHUB_WEBHOOK_SECRET / POST /api/_github/webhook immediate-refresh path, and the sandboxwarmpools: get RBAC grant. Also added a tenantPools row to the "Main sandbox values" table.
• pt-br/studio/self-hosting/deploy/kubernetes.mdx — mirrored translation of the above.

Consistency notes

• Checked quickstart.mdx, concepts.mdx, overview.mdx, and architecture.mdx for staleness — none reference warm pools or sandbox pooling, no changes needed.
• No other doc file references "warm pool" outside self-hosting/deploy/kubernetes.mdx, so no cross-reference fixes were needed.

pt-br was auto-translated (prose and headings translated; code blocks, URLs, component names, and product terms like "agent"/"connection"/"MCP" kept in English).
