Closes #118

directives_path was parsed and displayed by arjev inspect but never read. load_directives now resolves, in order: $ARJEV_DIRECTIVES_FILE, then directives_path, then arjev-directives.md at the first root that has one. With neither set, behavior is unchanged.

arjev inspect reports a set-but-missing directives_path as an advisory warning: line (counted in fold warnings). It is deliberately not a blocked: line: inspect's blocking set is documented as closed (no feeds / no roots / zero identity-bearing notes) and the loader degrades to empty rather than failing. Easy to flip to blocking if preferred.

Evidence

• New tests/test_directives_path.py (9 tests); 5 failed before the fix.
• pytest: 295 passed. ruff check .: clean.
• Docs: precedence in docs/agent-setup.md, entry under Unreleased in CHANGELOG.md.

Note: an ARJEV_DIRECTIVES_FILE that is set but missing still yields empty without fall-through (existing behavior; inspect does not warn about it).

Left as draft deliberately: this PR conflicts with night draft #116 (per-root field mapping) in src/arjev/inspect.py (3 hunks; _fold_lines signature and the warnings block). No conflict with #115 (directives.py, disjoint hunks). CI is green on this branch. Whichever of #116 / #120 lands second needs a small rebase in inspect.py; I did not rebase onto #116 because it is another agent's unmerged lane. Ready to mark ready on request.
