Expand repository instruction discovery for ReAct prompts

[Copilot]

Repository context loading previously only considered AGENTS.md/agents.md, which missed equivalent instruction files used by other agent ecosystems. This change broadens discovery while keeping deterministic precedence and existing prompt-safety behavior.

• Instruction source expansion

  • Extend candidate files to include:
    • AGENTS.md, agents.md
    • CLAUDE.md, claude.md
    • GEMINI.md, gemini.md
    • .github/copilot-instructions.md
  • Keep first-match-wins behavior using fixed candidate order and first non-empty readable file.

• Deterministic precedence made explicit

  • Replace helper indirection with a single static candidate array.
  • Preserve one-time load/caching via OnceLock.

• Prompt section generalization

  • Rename injected section label from AGENTS-specific wording to:
    • Repository agent instructions:
  • Retain existing markdown-fence sanitization before insertion.

static INSTRUCTION_FILE_CANDIDATES: &[&str] = &[
    "AGENTS.md",
    "agents.md",
    "CLAUDE.md",
    "claude.md",
    "GEMINI.md",
    "gemini.md",
    ".github/copilot-instructions.md",
];

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
