Slack Notifications, Agent Reliability & Bug Fixes

This release consolidates changes from v0.1.8–v0.1.10.

New Features

• Slack Draft Notifications — Product admins can now configure users to receive a direct message when a manually-triggered agent run completes a draft, keeping teams informed without manual polling. Includes a guided bot installation flow for first-time setup.
• Auto-Launch Slack Sharing — The Slack sharing dialog now opens automatically after publishing an entry, streamlining how updates are announced to your team. Slack posting is restricted to product admins only.

Bug Fixes

• Webhook Deduplication & Agent Resilience — Resolves an issue where GitHub release events triggered duplicate agent runs for the same release. Also improves agent job observability and overall fault tolerance for more reliable automated generation.
• Atlassian Tool Restrictions — The changelog agent now strictly limits which Atlassian tools it can access, preventing unintended calls to unauthorized services during automated generation.
• Configuration Fixes — Corrects Atlassian integration environment variable names to align with the production deployment, resolving connectivity issues in live environments.
• UI Stability — Fixes runtime errors and build warnings in the notifications interface for a smoother admin experience.
