feat: add issue and PR templates

Add structured GitHub templates based on analysis of 200+ closed PRs
and 50+ closed issues to improve submission quality:

Issue templates (YAML form-based):
- Bug Report: requires reproduction steps, expected/actual behavior,
  OS/Python/Hermes version. Optional root cause analysis field.
- Feature Request: requires problem/use case, links to skill-vs-tool
  guidance in CONTRIBUTING.md to reduce misguided tool PRs.
- Setup/Installation Help: requires install method, hermes doctor
  output, error logs, steps already tried.
- Template chooser config with links to Discord, docs, contributing guide.

PR template:
- Type of change selector (bug/feature/security/docs/tests/refactor/skill)
- Mandatory issue reference, changes list, testing steps
- Checklist: conventional commits, no duplicates, focused changes,
  tests pass, tests added, platform tested
- Dedicated 'New Skills' section asking if skill is broadly useful
  and properly formatted/tested

Key problems these templates address:
- Bug reports with no reproduction steps or environment info
- Duplicate/racing PRs (multiple people fixing same issue)
- Stale branches with 85+ unrelated file changes
- Junk skill PRs that should go to Skills Hub instead of bundled
- Missing tests on bug fix PRs
- No issue references on PRs
