Point AGENTS.md at the issue tracker for outstanding work

The agent instructions now say where new work goes -- an issue on the forge,
labelled by kind and blast radius and carrying status::grooming until its scope
is settled -- and that TODO.md is the record of where the library stands, what
is deliberately not wrapped, and which uncovered lines are uncoverable rather
than untested.

Also: a defect in a dependency is filed against that dependency. Three defects
in libakerror that cost this library a workaround each sat in this repository's
own notes without anybody upstream being able to see them, which is how a
workaround gets written once per consumer.

The KNOWN_FAILING_TESTS and pull-request rules now name the issue rather than a
TODO entry.

 ## Agent-Specific Instructions
 
+**Outstanding work goes in the issue tracker, not in a file.** Open an issue at
+<https://source.starfort.tech/andrew/libakstdlib/issues> — `tea issues create
+--repo andrew/libakstdlib` — naming the file and line, the functional
+consequence, and what closing it would touch. Label it by kind and blast radius
+and leave `status::grooming` on it until its scope and approach are settled.
+**Do not add outstanding items to `TODO.md`**: that file is the record of where
+the library stands, what is deliberately not wrapped, and which uncovered lines
+are uncoverable rather than untested. A description of work still to do goes
+stale the moment somebody does it, which is why the two are separated.
+
+**A defect in a dependency is filed against that dependency.** `libakerror` has
+a tracker on the same forge, and three defects that cost this library a
+workaround each sat in this repository's own notes for months without anybody
+upstream being able to see them. Comment the workaround at its site with the
+words "filed upstream" and delete it when the fix lands.

 Do not modify generated build trees, profiling artifacts, or untracked scratch
 files unless explicitly asked. Prefer small, test-backed changes and update
-`README.md` or `TODO.md` when changing documented workflows or known failures.
