[DEMO, do not merge] Validate #107's recipes-check on a real PR

[wjhrdy]

Throwaway PR to validate that #107's recipes-check workflow actually fires on a real pull_request event (its own PR doesn't touch a server.yml, so the path filter never triggers there).

Deliberately touches Qwen/Qwen3.6-35B-A3B/performance/server.yml to exercise all three finding tiers the check produces:

• reasoning-parser: deepseek_r1 (pre-existing on this branch, predates INFERENG-8300: Fix reasoning-parser and VL model attention backend for ROCm #104's fix) — high-confidence correctness diff
• tool-call-parser: hermes (deliberately wrong) — advisory-tier diff
• mm-encoder-tp-mode left unset — generic missing_local note

Will push a follow-up commit reverting both once the check's output is confirmed, then close without merging (base branch ci/recipes-check still has the stale pre-#104 reasoning-parser value, so this must never land).

Local dry run confirms all three findings render correctly; this PR exists to confirm the same on GitHub Actions infra + the PR-comment step.

Closing — validation confirmed (see comment history above). ci/recipes-check is about to be rebased onto main, which would make this branch's diff confusing to keep open.
