v0.2.8 — completion install + fuzzy preset hint + troubleshooting + templates

[0.2.8] - 2026-05-17

Added

• dvr completion install — friendlier wrapper around Typer's built-in
  --install-completion. Auto-detects the shell from $SHELL (zsh / bash /
  fish), runs the install, prints a clear "open a new shell" next-step.
  Pass --shell to override detection.
• dvr render submit fuzzy preset hint — when the preset name doesn't
  match exactly, the error now includes up to five close-match suggestions
  (difflib.get_close_matches, cutoff 0.4). e.g. H264 Master → hint
  Did you mean one of: 'H.264 Master'?
• README Troubleshooting — five expand/collapse Q&As covering the
  most common installation and bridge pitfalls (Resolve-not-running,
  Free vs Studio, Python 3.9 incompat, Windows custom install path,
  WI plugin not showing in Workspace menu).
• GitHub issue & PR templates under .github/:
  • ISSUE_TEMPLATE/bug_report.yml — structured form with dvr --version,
    Resolve version+edition, OS, dvr doctor --format json paste.
  • ISSUE_TEMPLATE/feature_request.yml — problem / proposed CLI shape /
    alternatives / scope dropdown.
  • ISSUE_TEMPLATE/config.yml — blank issues disabled, directs general
    questions to Discussions.
  • PULL_REQUEST_TEMPLATE.md — TDD/schemas/MCP-mirror checklist.

Tests

• 197 (was 186). Eleven new tests cover shell detection, the three
  completion failure modes, and the fuzzy preset hint.

No code-breaking changes.
