v0.6.5

• Add the plan-mode-report-problem skill, registered with ctx.register_skill. Ask the agent to "report a problem
  with Plan Mode": it checks /planmode status, collects versions and log lines, searches existing issues, drafts a
  report with the bug form's headings, and files it with gh only after you approve that draft. Security problems go
  to a private advisory instead, and problems in Hermes itself to the Hermes tracker. Hermes 0.21.6 and newer list the skill for the agent; older Hermes loads it by name
  (plan-mode:plan-mode-report-problem). While plan mode is on, the agent hands you the draft and the form link.
• Add contributor docs: AGENTS.md, CONTRIBUTING.md, SECURITY.md, a bug report form and a README troubleshooting
  section (#56).
