Feature/jira GitHub integrations

[ahmad-ajmal]

What and Why
Added Jira, GitHub, and X (Twitter) as external communication platforms, allowing the agent to listen for and respond to events from these services. Users can configure watch tags/labels to filter which events trigger the agent, avoiding unnecessary noise.

Changes

• Jira integration: authentication, issue polling, comment watching, and actions (add comment, search issues, search users, set watch labels/tags)
• GitHub integration: authentication, issue/PR polling, comment watching, and actions (add comment, search issues, set watch labels/tags)
• X (Twitter) integration: authentication and mention polling
• Mention-based triggers: agent only activates when a configurable tag (e.g. @craftbot) is found in comments
• Watch labels: filter events to only issues with specific labels
• Listener settings UI for Jira and GitHub (tag and label configuration)
• Integration icons for Jira and GitHub in the settings page
• Settings page refactor: split SettingsPage.tsx (4124 lines) into 11 focused module files

Behaviour

• When a watched tag is set (e.g. @craftbot), the poller only dispatches events where a comment contains that mention
• When watch labels are set, only issues with matching labels are polled
• If no tag or labels are configured, all events are watched
• Users can configure tags and labels from the web UI under each integration's listener settings
