refactor(packages): merge timeout/ into guard/, rename cordis/ to self-modification/

git mv timeout-policy beside repeat-tool-guard (both are loop-hygiene
policies on the tool-execution pipeline, and the timeout/ group name
collided with util/timeout) and tool-cordis into self-modification/
(naming the role the framework name obscured). Merged/renamed group
README triplets, tsconfig globs, generator sources, hierarchy tables,
catalogs, and the timeout-policy design note's group references
follow. Adds the fifth FIXME marker (dsh-timeout-guard, recorded as a
suggestion to settle at resolution time).

guard + self-modification suites: 197 passed.
