Add perf-scan.md agentic workflow that runs daily at 01:00 UTC and scans src/apm_cli/ for six algorithmic performance anti-patterns: A. Quadratic or worse loop nesting B. Linear scan inside a loop (set/dict opportunity) C. Unconditional expensive operations on hot paths D. Redundant env-var / config parsing in sequence E. Heavy top-level imports on CLI command modules F. Sequential I/O with no data dependency (parallelism opportunity) Each run creates a GitHub Issue titled: [perf-scan] YYYY-MM-DD -- performance opportunities found [perf-scan] YYYY-MM-DD -- no issues found (when clean) Issues are labelled 'performance' and 'automated'. Output is ASCII-only per the repository encoding rule. The companion instructions file at .github/agents/workflows/perf-scan.md documents the agent prompt, scan scope, and output contract for reference. The .lock.yml was generated with gh aw compile (v0.80.9). Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>

Pull request overview
Adds a new gh-aw agentic workflow (perf-scan) scheduled daily at 01:00 UTC to scan src/apm_cli/ for algorithmic performance anti-patterns and open a tracking issue per run, plus a companion reference doc.
Changes:
- Introduces
.github/workflows/perf-scan.mdwith the scan procedure and issue-format contract. - Adds the compiled workflow
.github/workflows/perf-scan.lock.yml. - Adds
.github/agents/workflows/perf-scan.mdas a standalone reference for scope and output contract.

TL;DR
Adds a daily agentic workflow (
perf-scan) that scanssrc/apm_cli/foralgorithmic performance anti-patterns and opens a GitHub Issue with findings
every morning at 01:00 UTC.
Problem (WHY)
PR #2124 landed four algorithmic perf fixes and a
performance-expertagentwith a full algorithmic lens. Without a recurring automated scan, new regressions
will silently accumulate between manual audits.
Approach (WHAT)
A GitHub Agentic Workflow that:
