chore: sync catalog with upstream docs

[github-actions]

Auto-generated by Catalog drift (workflow).

Upstream sources changed; this PR re-runs the sync scripts:

• npm run sync:settings
• npm run sync:env-vars
• npm run sync:hooks
• npm run sync:sub-agents
• npm run sync:mcp
• npm run sync:permissions
• npm run sync:keybindings
• npm run sync:cli-reference
• npm run sync:model-config

Drifted catalogs:

catalog/settings.json
catalog/env-vars.json
catalog/hooks.json
catalog/sub-agents.json
catalog/cli-reference.json

Review the diff, then merge to land. If something looks wrong,
close this PR and dig into the offending sync script — the
fetchedAt-only case is normalised out before this body is
generated, so anything here is real content drift.
