fix: invalid // comment headers in YAML/Justfile

[hyperpolymath]

Problem

The estate-standardization script wrote the Owner: header line using C-style // comment syntax into files that use # comments. // is not a valid comment in YAML or in just, so it breaks those parsers.

Fix

Changed the leading // Owner: to # Owner: in the four affected files only:

• .gitlab-ci.yml (line 2) — YAML
• .pre-commit-config.yaml (line 2) — YAML
• Justfile (line 2) — just
• container/.gatekeeper.yaml (line 2) — YAML

Each was // Owner: Jonathan D.A. Jewell <j.d.a.jewell@open.ac.uk> and is now # Owner: ....

Left as-is (correct)

.adoc files (e.g. README.adoc) keep // — that is a valid line comment in AsciiDoc, so they were intentionally not touched. No .md or .rs files were modified.

Verification

git grep -nI '^// Owner:' -- '*.yml' '*.yaml' Justfile '**/Justfile' returns no matches after the fix.
