chore: move root config files to .config/

Cascaded from socket-wheelhouse. Moves the root config files into
.config/ (with leading dot dropped from the names since they're
already collected):

  .oxlintrc.json    → .config/oxlintrc.json
  .oxfmtrc.json     → .config/oxfmtrc.json
  lockstep.json     → .config/lockstep.json (if present)
  lockstep.schema.json → .config/lockstep.schema.json (if present)
  tsconfig.json     → .config/tsconfig.json
  tsconfig.dts.json → .config/tsconfig.dts.json (if present)
  tsconfig.test.json → .config/tsconfig.test.json (if present)

Internal updates:
* .config/tsconfig.json paths re-rooted (../src etc.)
* .config/oxlintrc.json jsPlugins → './oxlint-plugin/index.js'
* tools that auto-discover tsconfig.json now pass -p .config/tsconfig.json
* lint / format / lockstep scripts pass -c / -p flags pointing at
  the new paths
* package.json scripts (format, type, lockstep) updated to reference
  .config/ paths
* CI workflows: lockstep.json refs updated to .config/lockstep.json
