Renames DDIR's columnar runtime module from src/corgi/ to src/runtime/. Today crate::corgi::… (DDIR's runtime) and corgi::… (the external crate) both appear throughout, and a reader can't tell which is meant. This is a pure rename, with no behaviour change. 33 files, +95/−95.

What changes

• git mv interactive/src/corgi/** interactive/src/runtime/**: 14 files, so history follows.
• 66 crate::corgi:: paths become crate::runtime::.
• 27 interactive::corgi:: paths become interactive::runtime::, in the server crate, the tests, bench/ldbc/client.py and the server README.
• pub mod corgi; becomes pub mod runtime; in lib.rs.
• The README's Architecture section names runtime/.

Filtering the diff for lines that aren't one of these path rewrites leaves only the mod line and that README line.

Unchanged on purpose

• Every reference to the external crate: corgi::Value, corgi::Shape, use corgi::…, corgi::bytes, and the Cargo dependency.
• backend/corgi.rs, tests/corgi_backend.rs and tests/corgi_chunk_merge.rs. They name the corgi-backed implementation and what it's tested on.
• Type names with the Corgi prefix. A follow-up could rename the ones that name a role rather than corgi-valued data:
  • data types, which keep the prefix: CorgiChunk, CorgiContainer, CorgiChunker, CorgiDistributor;
  • role types, which could be named for their role: CorgiBackend, CorgiImport, CorgiPact, CorgiHalfJoin, CorgiJoinBackend, CorgiReduceBackend.
• runtime/mod.rs's header still reads "The corgi rendering substrate's internals". It describes the code, not the path.

Checks:

• cargo test -p interactive -p ddir-server.
• Clippy: 226 warnings on this branch and 226 on master-next, and the two lists are identical once src/runtime/ is mapped back to src/corgi/.
• Every step of the release LDBC job, against a release server built from this branch, including authored/check.py --fixture --workers 4.
• Release explain suite: 29/29.
• Differential testing, seeds 20,261,023–20,266,022 with all nine oracles: 5,000 passed.
• git grep "crate::corgi\|interactive::corgi\|src/corgi" returns nothing.
