PBGC had shrunk to a single module that converts pulsar_std's #[blueprint] registry into Graphy node metadata, and this plugin was its only user. This PR moves that conversion into the plugin, so PBGC can be removed.

Changes

• New src/std_nodes.rs with the conversion code taken from PBGC's metadata.rs. It exposes extract_node_metadata, node_metadata (built once on first use) and StdNodeProvider, Graphy's NodeMetadataProvider for the data-flow checks.
• The three call sites (palette loading, the validation stage and the compiler's preflight check) now use it.
• The plugin depends on pulsar_std directly instead of on PBGC. The rev is the same Pulsar-Native rev the other Pulsar-Native dependencies use.
• PBGC's three tests are now tests/std_nodes.rs.
• Comments that described PBGC as the source of the metadata now name pulsar_std or Graphy.

extract_node_metadata never fails, so its Result is gone. So are PBGC's helpers that nothing here called (get_categories, get_nodes_by_category, find_node).

This also fixes the check that failed on Far-Beyond-Pulsar/PBGC#12. That PR's standalone build used an old pulsar_std whose delay node had no Completed exec output. The plugin builds against the current one, and the test passes.

Pulsar-Native drops the PBGC submodule and pins this branch in a companion PR (link below).

Checked

Inside a Pulsar-Native checkout with PBGC removed:

• cargo test -p blueprint_editor_plugin --tests: io_formats 8 pass, std_nodes 3 pass.
• rustfmt --check passes on the touched files.
