Use folded description: >- instead of | so WORKFLOW_DESCRIPTION reaches threat detection as one line #402

Most workflows here write their frontmatter description as a literal block (description: |): 20 of them, against 3 that use > and the rest that use a plain string. The descriptions are prose wrapped at about 80 columns, so | keeps that source wrapping as real newlines in the value. Switching them to >- (folded, no trailing newline) would give the sentence as written.

Where the description ends up

gh aw compile copies description into two places in the lock file:

1. The header comment at the top of *.lock.yml.

2. WORKFLOW_DESCRIPTION, an env var on the threat-detection job. setup_threat_detection.cjs substitutes it into the detector's prompt, where the template puts it inside a bullet:

   - Workflow name: {WORKFLOW_NAME}
   - Workflow description: {WORKFLOW_DESCRIPTION}
   - Full workflow instructions and context in the prompt file
   

The second one is what the description is for at runtime: it tells the detector what the workflow is meant to do, so it can judge whether the agent's output fits.

What | does to it

With issue-triage.md as it is today, the compiled value is:

WORKFLOW_DESCRIPTION: "Triages new and reopened issues by assessing completeness, setting issue type\nand priority labels, finding duplicates, and posting a concise maintainer-facing\nreport with actionable next steps."

so the detector receives:

- Workflow description: Triages new and reopened issues by assessing completeness, setting issue type
and priority labels, finding duplicates, and posting a concise maintainer-facing
report with actionable next steps.

The line breaks come from the editor's wrap column, not from the meaning, and they break the bullet the template sets up. A model will most likely still read it correctly, so this is a tidiness fix, not a bug. But the value is going into a prompt, and >- gives exactly the one-line string the template expects:

- Workflow description: Triages new and reopened issues by assessing completeness, setting issue type and priority labels, finding duplicates, and posting a concise maintainer-facing report with actionable next steps.

Cost

The source .md looks the same: same indentation, same wrapping, one changed indicator. When compiled with gh-aw v0.89.21, the only other lock-file changes are frontmatter_hash and the header comment, which becomes one long line instead of three wrapped ones. Nobody needs to read that comment closely, since the .md is right there.

I made this change to a copy of issue-triage.md in my own repo: shbernal/pptx-ts#276.

Suggestion

Change description: | to description: >- in the workflows that use it and recompile. The three that use > could become >- too, which drops the trailing newline (the compiler already trims it, so in practice they produce the same output). If you'd take a PR for this, I'm happy to send one.
