Fix evaluation.yml run-name: quote expression so '#' isn't a YAML comment

[YuliiaKovalova]

Problem

Every evaluation.yml run on main has failed since #746 merged (13:50), with GitHub reporting "This run likely failed because of a workflow file issue" and no jobs starting. This is not caused by #754 (baseline reuse) — that feature's eval run succeeded at 13:17; the first failure is the #746 merge commit.

Root cause

#746 added a run-name as an unquoted plain YAML scalar:

run-name: ${{ inputs.pr_number != '' && format('Evaluate PR #{0} @ {1}', inputs.pr_number, inputs.head_sha) || '' }}

In YAML, a space followed by # begins a comment. So #{0} @ {1}', inputs.pr_number, inputs.head_sha) || '' }} is stripped as a comment, leaving an unterminated ${{ expression. The file still parses as valid YAML (which is why yaml.safe_load and a casual review pass), but the GitHub Actions workflow parser rejects the broken expression and refuses to start any run.

Fix

Wrap the value in double quotes so the # stays inside the scalar:

run-name: "${{ inputs.pr_number != '' && format('Evaluate PR #{0} @ {1}', inputs.pr_number, inputs.head_sha) || '' }}"

The inner expression only uses single quotes, so double-quoting is safe.

Verification

• actionlint on the fixed file: 0 errors (previously: got unexpected EOF while lexing end of string literal at line 34).
• One-line change; no behavioral change to the run name itself.

Pull request overview

Fixes a GitHub Actions workflow parsing failure introduced by an unquoted run-name expression containing #, which YAML treats as a comment delimiter in plain scalars—resulting in a truncated/invalid ${{ ... }} expression and preventing the workflow from starting.

Changes:

• Quote the run-name value in .github/workflows/evaluation.yml so # remains part of the string and the expression remains intact.
