chore: add templates, CLAUDE.md, release-version check

[GigaHierz]

Bootstraps this repo onto pm-kit — templates and CLAUDE.md only. The repo's existing CI (lint, build, jest, CLI smoke test) is untouched.

What this adds

• Issue/PR templates: .github/ISSUE_TEMPLATE/ (bug_report, task, user_story, config) and .github/PULL_REQUEST_TEMPLATE.md
• Shared rules (synced from pm-kit): .claude/shared/engineering-rules.md, money-path-checklist.md, tester-mode-pattern.md
• CLAUDE.md: repo-owned router for Claude sessions — project overview, commands, architecture pointers, shared-rule imports, and gotchas (notably: template changes must be verified by scaffolding and building a generated project, since the generated output is the product)
• renovate.json: dependency update config
• .github/workflows/verify-release-version.yml: thin caller of pm-kit's reusable workflow; on push of tags v*, verifies the git tag equals package.json version and that CHANGELOG.md has an entry (this is a published npm package — publish.yml already triggers on v* tags)

What this does NOT do

• No changes to existing CI (ci.yml), publish workflows, source code, tests, or templates — 0 existing files modified, 11 files added.

Branch-protection note

This repo's CI job is named test, so the required-status-check context in the branch-protection ruleset must be test (not ci / ci).
