Three classes of drift cleaned up across 85 .md files:
- Em-dashes: replaced ` — ` with the contextually correct separator
(colon for `term: explanation`, period to split clauses across
sentences/source lines, parentheses for asides, semicolon for
tight-linked continuations). Two intentional exceptions remain
in `docs/contributing/documentation.md` (the rule literal) and
inside a fenced ```sh block in `docs/contributing/actions/debugging/ci.md`.
- SPOT self-labels: rewrote "This is the SPOT for X" to describe
the subject directly ("This directory holds X" / "This file
describes X"). Cross-references to other artefacts' canonical
role remain unchanged.
- Heading-emoji position: moved leading-emoji headings (`# 🧩 Title`)
to trailing position (`# Title 🧩`) per the headline rule that
emojis MUST come after the title text.

Add tests/lint/repository/test_markdown_links.py — a hard-fail lint
test that scans all git-tracked markdown files for broken relative and
repo-root-absolute links. Skips external URLs, anchor-only links, fenced
code blocks, and placeholder targets.
Apply documentation.md rules to all staged files: add emojis after
headlines in docs files, remove emojis from role README headings,
standardize Credits sections to the canonical format, remove empty
sections and orphaned sentences referring to missing documentation files,
fix raw URLs and incorrect link text across role READMEs and docs.
