Document that package.json aliases may target only direct subfolders of src (#21)

Follow-up to #20, which was merged before this landed.

bot-agents has no `package.json` `imports` aliases (`src/` is flat and everything imports relatively), so no code changes. This records the new rule in the docs:

- `.agents/memory/imports-aliases-barrels.md`: aliases may target only a direct subfolder of `src/` (its `index.ts` or a `#x/*` pattern); nothing outside `src/`, not `src/` itself, not deeper folders; such code imports relatively.
- `.agents/memory/tests-layout-vitest.md`: `tests/` reach the public entry through a relative import, not a `#plugin` alias.
- `.agents/skills/migrate-deno-repo/SKILL.md` and `AGENTS.md`: same rule.

`vp check`, `vp test`, and `damem doctor` pass.
