Feature: Issue workflow (Forest note -> GitHub issue)

[bwl]

Use case

• Capture a bug/feature once in Forest, then optionally promote to a GitHub issue.
• Keep a durable knowledge record (repro/context/links) even if issue trackers change.

Current workaround

• Manually run forest capture with a template, then gh issue create.
• External skills/personas (like JACK) glue this together.

Proposal

• Add: forest issue bug and forest issue feature (interactive prompts).
• Flow:
  1. Prompt for required fields (bug: symptom/repro/expected/actual/context; feature: use case/workaround/proposal)
  2. Create a Forest note tagged project/forest + bug/* or feature/*
  3. Optionally create a GitHub issue via gh (repo/labels/title/body), including the Forest note short id
• Flags:
  --repo, --label, --dry-run, --no-gh, --json

Acceptance criteria

• One command produces both the Forest note and (optionally) the GitHub issue URL.
• Works non-interactively when flags provide required fields.
