Document two new Redis connection reliability settings merged in
open-webui/open-webui#23573 and open-webui/open-webui#23571:

- REDIS_HEALTH_CHECK_INTERVAL: application-level PING on idle pooled
  connections before reuse, preventing 'Connection reset by peer' errors
  when the Redis server reaps stale connections via its timeout setting.

- REDIS_SOCKET_KEEPALIVE: TCP SO_KEEPALIVE on all Redis client sockets,
  enabling kernel-level dead-peer detection for half-closed connections
  caused by silent firewall/LB resets or NIC flaps.

Also updates REDIS_SOCKET_CONNECT_TIMEOUT description to reflect that
it now applies to all client types (plain, cluster, sentinel), not just
sentinel connections.

Updated files:
- reference/env-configuration.mdx: new env var entries with tips
- getting-started/advanced-topics/redis.md: connection health checks
  section, complete example configs, and new troubleshooting entry

…or builtin tools

Document changes from the automation tools PR:

Automation builtin tools:
- New 'Automations' builtin tool category with 5 tools: create_automation,
  update_automation, list_automations, toggle_automation, delete_automation
- Added to builtin tools table, tool reference (with parameters/output),
  and granular categories table in tools/index.mdx
- New 'Managing Automations from Chat' section in automations.mdx with
  available tools, requirements, and usage examples

User-level RBAC permission gating:
- Builtin tools now respect features.* RBAC permissions (not just
  per-model toggles and global config flags)
- Added warning admonition documenting which tool categories require
  which features.* permission (memory, web_search, image_generation,
  code_interpreter, notes, channels, automations)
- Admins always pass these checks

Also updated models.md Builtin Tools list to include Task Management
and Automations categories.

Document two new admin-configurable limits for automations:

- AUTOMATION_MAX_COUNT: caps the number of automations a non-admin
  user can create (checked on creation only)
- AUTOMATION_MIN_INTERVAL: enforces a minimum recurrence interval in
  seconds (checked on creation and update; one-time schedules exempt)

Both are PersistentConfig variables (env + Admin Panel), default to
empty (no limit), and admins bypass all checks.

Updated files:
- reference/env-configuration.mdx: new env var entries with tip table
- features/chat-conversations/chat-features/automations.mdx: new
  'Admin Limits' section with settings table and behavior notes

Reflects the 0.9.0 builtin task-management tool split: one tool to lay
out the initial checklist, another to update a single task's status by
id after each step.
