Subject: [PATCH 02/11] fix(shared): slashed extensionless inline code with a
 line suffix stays plain code

`I/W217:220` and `foo/TODO:12` no longer become file chips. A relative
slashed inline-code path with a position now needs a file extension or a
conventional extensionless name (Makefile, Dockerfile, ...); explicit
./, ../, ~/ and absolute paths are unchanged.

Fixes #22181

Subject: [PATCH 05/11] test: store the #22181 placeholder source as .txt so
 knip ignores it

seed.py renames it back to markdownLinks.ts in the runtime workspace, so the
seeded bytes and paths are unchanged.
