Move the action from Deno to Node.js and Vite+ (#20)

## Summary

Moves `commons/bot-agents` off Deno. The action's TypeScript now runs directly on the job image's Node.js (`node src/<phase>.ts`, using Node's built-in type stripping), with no build step and still no runtime dependency. Repository checks move to Vite+ (`vp check`, `vp test`).

## What changed

- **Runtime.** `action.yml` runs `prepare.ts`, `run.ts`, and `post.ts` with `node` instead of `deno run -A`. `package.json` (`"type": "module"`, `engines.node >=24.2` for `import.meta.main`) is now copied into the root-owned source copy by `scripts/protect-source.sh`.
- **Profiles.** `profiles.yml` → `profiles.json`, with the same content (encrypted values unchanged), parsed with `JSON.parse`. This drops the only runtime dependency (`@std/yaml`).
- **Deno APIs → Node.**
  - `src/command.ts` wraps `child_process.spawn` with the old `Deno.Command` shapes: `output()`/`spawn()`, `clearEnv`, `uid`/`gid`, and Deno's stdio defaults (stdin inherited; stdout/stderr piped for `output()`, inherited for `spawn()`). A signal exit maps to `128 + signo`. Status settles on process exit.
  - `src/errors.ts` maps `NotFound` to `ENOENT`/`ESRCH`.
  - fs, path, stream, and readline calls are mapped one for one. `makeTempFile` becomes an exclusive `wx` 0600 create.
- **Size refactors.** These are needed for Oxlint's default limits. There are no behavior changes and no overrides for source files.
  - `run.ts` is split into `run-context.ts`, `agents.ts`, and `agent-{claude,codex,opencode}.ts`.
  - `post.ts` is split into `post.ts` and `post-artifacts.ts`.
  - `parseCredentials`, `readOutcome`, and `postRuntime` are broken into helpers.
  - Loops that awaited sequentially became recursion or a `reduce` chain, so they stay sequential. `/proc` status reads became `Promise.all`.
  - `src/json.ts` adds type guards in place of `as` casts.
- **Tests.** The 58 `Deno.test` cases were converted to Vitest with the codemod, and its TODOs were finished by hand.
  - Unit tests are `src/*.test.ts`; the repository-level workflow test is `tests/workflow.test.ts`.
  - Root-only tests are now `test.skipIf(!IS_ROOT)`, so they show as skipped instead of silently passing.
  - New `tests/entrypoints.test.ts` runs each phase under real Node to prove its whole import graph loads.
- **Config.** The only config files are `package.json`, `tsconfig.json`, and `vite.config.ts`, plus `package-lock.json`.
  - Lint uses Oxlint correctness/suspicious/pedantic/perf at error, with default limits and type-aware checks.
  - `scripts/project-lint.ts` holds the rule list. It maps Deno's `recommended` rules that fall outside those categories, adds the template's `id-match`, `no-disable-comments`, and `no-non-ts-imports`, and maps Deno's `no-window`/`no-process-global`/`no-node-globals` to `no-restricted-globals` (so `process`/`Buffer` come from `node:` imports).
- **CI.** `.gitea/workflows/check.yml` runs `node --version`, `npm ci`, `npx vp check`, and `npx vp test` in the default runner image.
- **Formatting.** Oxfmt formatting is a separate first commit, so the second commit shows only the semantic diff.
- **AGENTS.md** is updated for the new toolchain.

## Deviations / risks

- **Live `@main` switch.** Six consumer repos use `commons/bot-agents@main`, so merging switches all of them at once. Suggested before merging: tag the current `main` (e.g. `deno-final`) as a rollback target, and canary this branch from one consumer (`uses: …/commons/bot-agents@node-migration`) on a throwaway PR.
- **Node version.** `post.ts` relies on `import.meta.main`, which needs Node ≥ 24.2. DANNYEC's cached `node:24-bookworm` minor is unknown (`forcePull=false`), and the CI job now prints `node --version` to confirm it.
- **Deno stays in the global install.** `deno` remains in the action's global npm install because agents still verify Deno-based consumers (memona, memona-home). Remove it once those repos move.
- **`prefer-readonly-parameter-types` is off.** This pedantic rule is turned off, as in the explicit-types template and the app repos, because Node/web types (`Response`, `Stats`, `RequestInit`) can never satisfy it. `scripts/**` has one narrow override (`no-unsafe-enum-comparison`) for AST node `type` comparisons.
- **Stricter validation of malformed input.** For valid input, behavior is unchanged. A few validations are stricter where the old code would have used a malformed value:
  - Gitea `/user` and comment responses are checked.
  - The runtime manifest and the outcome's profile type are checked against known values.
  - Some type-check errors are now `TypeError` (same messages).
- **@cunarist lint plugins.** "CI fails until @cunarist/eslint-plugin-* are published" does **not** apply here. This repo's Deno setup enabled no plugin, so it depends on none of `@cunarist/eslint-plugin-*`, and CI can pass as is.

## Verification

- `vp check`: formatting, lint (0 warnings), and type check all pass.
- `vp test` as a normal user: 56 passed, 5 root-only skipped.
- `vp test` as root in `node:24-bookworm` (Node v24.22.0, the CI image): all 61 passed, including the UID isolation, process cleanup, and `prepare.ts` cleanup tests.
- End-to-end smoke as root in `node:24-bookworm`, with fake `codex`/`claude`/`npx` binaries and a fake Gitea, through `protect-source.sh` → `prepare.ts` → `run.ts` → `post.ts`:
  - Codex hit "usage limit" and fell through to Claude.
  - Agents ran as UIDs 20000/20001 without the master key.
  - The Codex login was persisted to `/root/.codex/auth.json` (0600).
  - The PR review with an inline comment was posted with the reviewer token.
  - Runtime credentials were removed and the git author was configured.

+description: Ask one decision at a time with a code example, follow ESLint/ecosystem conventions and ask before deviating, keep config minimal, and never block when the user is away
+---
+
+## Asking
+
+- **One question at a time.** Each decision question stands alone, with the
+  options and a recommendation.
+- **Show code.** The user is new to the ESLint ecosystem and asked for
+  example code blocks whenever possible (2026-10-14): before/after snippets
+  or config examples, not prose alone.
+
+  ```ts
+  // A. per-file override          // B. refactor with a barrel
+  overrides: [{ files: [...] }]    import { a, b } from "#ui";
+  ```
+
+- **Keep answers short.** State the decision and what changed; detail belongs
+  in `.agents/memory/`, not chat.
+- The user often probes with "why?" and "is this the simplest form?". Have
+  the reason ready, and prefer the option with fewer lines, fewer files, and
+  fewer custom types when the result is equivalent.
+
+## Conventions over invention
+
+- Follow ESLint's and the wider ecosystem's conventions (typescript-eslint,
+  unicorn as references): `docs/rules/<rule>.md`, one plugin per package,
+  flat configs at `plugin.configs`, `meta.docs.url`, `index.ts` entries.
+- **Any deviation is a question, not a default**, even one carried over from
+  the Deno version. The user was unhappy when rule docs were quietly placed in
+  `src/` ("You should have asked me about this though. We should respect
+  ESLint's way").
+- Before finishing structural work, compare against well-known projects and
+  list every difference for the user.
+
+## When the user is away
+
+- **Never block on the user.** No approval requests, no waiting. Pick the
+  conservative option consistent with these notes, write the choice and its
+  reason in the PR or report, and continue. (An idle approval request once
+  cost hours; the user was emphatic.)
+- Log open questions where the user will look: the PR body, and the shared
+  questions file the coordinator names (during the migration,
+  `~/.local/share/deno-migration/morning-questions.md`).
+- Hard limits still hold without asking: no merging, no publishing, no
+  archiving, no pushing to `main`, no external state changes.
+
+## Working style the user expects from agents
+
+- Keep the main conversation free: repo edits, commits, and long checks run
+  in background subagents.
+- Fan independent work out to many parallel subagents (more than five when it
+  splits), each in its own worktree when they share a branch.
