sprout-agent had zero support for AGENTS.md or SKILL.md — the only context it got was a hardcoded 1-line system prompt plus whatever sprout-acp assembled. Other harnesses (goose, Claude Code) handle their own loading, so this belongs in sprout-agent, not sprout-acp. At session/new time, walks from git-root to CWD collecting AGENTS.md files, scans .agents/skills/, .goose/skills/, .claude/skills/ for SKILL.md entries with YAML frontmatter, and prepends the combined content to the system prompt. SPROUT_AGENT_NO_HINTS=1 disables.
Reuse mcp::truncate_at_boundary instead of duplicating it in hints.rs, store effective_system_prompt as Arc<str> to avoid a 128KB clone per session/prompt, and strip WHAT doc comments per project style.
…archy sprout-agent only loaded hints from the git-root→CWD chain, missing user-level instructions entirely. Adds home directory as the first layer: ~/AGENTS.md is prepended before project hints, and ~/.agents/skills/ is scanned after CWD-relative dirs (project wins on name conflict). Includes dedup guard when ~ is already in the chain.
