fix: remove the Pythinker Datasource plugin

The plugin proxied every tool call to api.pythinker.com/coding/v1/tools,
a gateway backend that was never built — every call returned a plain
404, so the plugin never worked. Rather than run a dead marketplace
entry, drop the plugin, its CDN package, and its docs section entirely.

build-cdn.mjs now skips a plugin channel directory that doesn't exist
instead of throwing, since removing the only official-tier zip makes
git drop the now-empty plugins/cdn/official/ directory on checkout.

Also move lint-staged's oxlint invocation into .lintstagedrc.mjs so it
filters out oxlint-ignored paths before running: oxlint exits non-zero
on an all-ignored fileset, which broke committing an isolated change to
a script under apps/*/scripts/ (an intentionally oxlint-ignored path).
