[AISOS-2496] Test Forge bug workflow: correct stale draft-attachment documentation

[forgeSmith-bot]

Summary

This PR corrects stale documentation regarding Forge's interactive draft review process. It replaces outdated references to serializing proposed items into JSON draft files and uploading/downloading them as Jira attachments with the correct implementation of using state-backed durable workflow state (plan_draft and tasks_draft).

Changes

Documentation Updates

• docs/guide/labels.md: Updated the forge:direct-mode label description and interactive draft review workflow steps to reference state-backed durable workflow state instead of JSON attachments, and updated the /forge approve command description.
• docs/guide/feature-workflow.md: Updated Epic Decomposition and Task Generation guides to remove references to forge-epics-draft.json and forge-tasks-draft.json attachments, replacing them with state-backed workflow state tracking.
• docs/developer-guide.md: Cleaned up the /forge approve description in the command reference table to remove references to deleting draft attachments.

Implementation Notes

• This is a documentation-only fix intended to align the user guides and developer references with the actual, current implementation of the Forge state machine.
• A repository-wide search was conducted across all Markdown documentation files to ensure no lingering references to the old attachment-based workflow remain.

Testing

• Verified that all documentation changes correctly represent current system behavior.
• Performed a workspace-wide search for deprecated terms such as forge-epics-draft.json, forge-tasks-draft.json, and draft attachment to confirm no other stale occurrences remain.
