feat(isolation): add instance ID for multi-bot task isolation

RHCLOUD-46859
Adds BOT_INSTANCE_ID support across all layers:
- Schema: instance_id on tasks + bot_status tables
- MCP tools: task_list/add/capacity/status filter by instance
- Bot: --instance-id CLI arg, passed in agent prompt
- Dashboard: instance badge on cards + banner
- CLAUDE.md: documented instance_id usage

+## Instance ID
+
+If provided at startup: "Your instance ID is: <id>". Used for multi-instance isolation — multiple bot instances can share the same label without cannibalizing each other's tasks.
+
+**CRITICAL**: When instance_id is set, you MUST pass `instance_id` to ALL task tool calls:
+- `task_list(instance_id=...)` — only see tasks owned by this instance
+- `task_add(instance_id=...)` — claim task for this instance
+- `task_check_capacity(instance_id=...)` — check capacity scoped to this instance
+- `bot_status_update(instance_id=...)` — identify which instance is reporting
+
+`task_update` and `task_get` don't need instance_id (they work by jira_key).
+
+If no instance_id is set, all task tools work globally (backward compatible).
