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.

-Template: `cunarist/eslint-plugin-explicit-types` on `main`. Read its
-`AGENTS.md`, `vite.config.ts`, `scripts/project-lint.ts`, `package.json`, and
-CI before starting, and copy their shape. Never ask the user mid-way when
-they're away: decide by the memories, record the choice in the PR.

-Branch `node-migration` (apps) or `initial-port` (new plugin repos); one PR
-with everything.
-
-**Inventory first**
-
-- [ ] List every `deno.json` task, import-map entry, lint rule (tags,
-      includes, `@hugoalh`, custom plugins), test, `Deno.*` call, JSON/CSS/SVG
-      import, and every place the output is consumed (Rust, HTML,
-      Containerfile, CI).
-
-**Toolchain**
-
-- [ ] `package.json` in the required key order, `engines.node ">=22"`, no
-      `packageManager`, no `peerDependencies`; `npm install`; commit
-      `package-lock.json`.
-- [ ] `tsconfig.json` from the template; `vite.config.ts` with `fmt:
-      { sortPackageJson: false }` and the category-based `lint` block.
-- [ ] Delete `deno.json`, `deno.lock`, and Deno-only files. `mod.ts` →
-      `index.ts`; `deno.json` imports → `package.json` `imports` (`#x/*`
-      patterns for trailing-slash mappings); `jsr:`/`npm:` → npm packages.
-
-**Code**
-
-- [ ] Only `.ts` files; no non-`.ts` imports: CSS via `<link>`, JSON and SVG
-      as `.ts` modules, icons in memona's style.
-- [ ] `Deno.*` → `node:*` / `process`. Generated JS written as `.ts`, built,
-      gitignored.
-- [ ] Decorators stay standard with `accessor`; add `scripts/decorators.ts`
-      if the repo has any. Lit repos: `scripts/lit-check.ts` + `npm run
-      lit-check`.
-
-**Lint**
-
-- [ ] `scripts/project-lint.ts` copied; old local Deno lint rules ported into
-      it; parity mapping for every former rule; `id-match`; no disable
-      comments; no source `overrides`; refactor size-rule hits.
-
-**Tests**
-
-- [ ] `Deno.test` → Vitest (codemod, then finish TODOs); unit tests next to
-      code, integration in `tests/`; no case dropped.
-
-**Build, ship, CI**
-
-- [ ] `vp build` in app mode with the same output paths, or `vp pack` for
-      packages. Containerfile node stage on `node:24-alpine`. CI with
-      `setup-vp`: `vp check`, build, `vp test` (+ lit-check). Packages:
-      release-triggered `publish.yml`.
-- [ ] `AGENTS.md` with the damem header, `.agents/` notes from the damem kit,
-      README updated (Node.js 22+, no Deno instructions). `damem doctor`
-      clean.
-
-**Finish**
-
-- [ ] `vp check`, `vp test`, build all pass locally; the app runs.
-- [ ] Commit in plain imperative sentences; open the PR (summary, changes,
-      parity mapping, deviations/risks, "CI fails until @cunarist/eslint-plugin-*
-      are published" if relevant, verification, footer line).
-- [ ] Run `review-cycle`. Never merge, publish, or archive.
