What

• Comment job: final-check.yml's comment job now cleans the report before TechEngineBot posts it:
  • Every @ is dropped.
  • #123, GH-123 and /issues/N, /pull/N and /discussions/N links are broken with a zero-width space.
  • The body is capped at 65,000 characters, under GitHub's comment limit.
• Token wording: it no longer says "for this repository only". One fine-grained TechEngineBot token, with Pull requests: read and write, covers the five GetTechAPI repos that now have a final check.
• README: one sentence on the above.

Why

The check job runs the PR's code. On a GitHub-hosted runner, that code can rewrite anything later in the job, the report included, and until now only the check job cleaned it. The comment job runs none of the PR's code, so cleaning there means the bot can't be used to mention people or cross-reference issues, whatever a PR contains.

The same lines are going into the other repos' final checks: GetTechAPI/TechEngine#128, GetTechAPI/TechMachine#8, GetTechAPI/game-catalog#2 and GetTechAPI/cpu-engineering-samples#37.

Checks

I ran the script, extracted from the YAML, in node against stubs:

• A normal report, with the marker, the run link and Mermaid colours, is posted unchanged.
• @user, #12, GetTechAPI/TechEngine#127, GH-7 and an issue URL are neutralised.
• A report without the marker posts nothing.
• A 70,000-character body is cut to 65,000.
• Re-running against an identical existing comment writes nothing.
