Restructure to skill-manager conventions

- Move the TypeScript project under scripts/ (src, tsconfig,
  package.json, pnpm lockfile/workspace, canonical .gitignore);
  drop the npm package-lock
- Add scripts/Taskfile.yml aggregator plus .scripts modules
  (loggers, base, cli) with build, run, and validate tasks
- Move the six SKILL-*.md docs into references/ with kebab names
  and extract the connector-routing sections from SKILL.md into
  references/routing-best-practices.md (SKILL.md 666 -> ~310 lines)
- Add license/metadata/compatibility frontmatter, an Available
  scripts section, and update all CLI paths in README and references

skill-manager validate: 13/13 passed, 0 warnings.
