Export the whole overrides array from project-lint and document the lint config

Groups the flat `src/` into cohesive modules and turns on the published lint plugins. No behavior change.

## Module layout

Each module is a direct `src/` subfolder with an `index.ts` barrel and a `#` alias in `package.json` `imports` (layer order, top first):

| Alias | Files |
| --- | --- |
| `#prepare` | `index.ts` (the prepare phase entry point) |
| `#run` | `index.ts` (the run phase entry point) |
| `#post` | `index.ts` (the post phase entry point), `post.ts`, `post.test.ts` |
| `#agents` | `auth.ts`, `opencode.ts` (Codex / Claude Code sign-in, OpenCode args and output) |
| `#processes` | `child.ts`, `isolation.ts` |
| `#runtime` | `runtime.ts`, `credentials.ts` |
| `#profiles` | `profiles.ts` |
| `#common` | `errors.ts`, `json.ts` |
| `#testing` | `index.ts` (unchanged) |

Every top-level entry of `src/` is an aliased module folder. Tests stay next to their code as `*.test.ts`. Each phase's `index.ts` is its entry point, and `action.yml` now runs `node src/<phase>/index.ts`. The post phase's logic moved to `src/post/post.ts` so its test can import it; `index.ts` keeps the env reading and the `import.meta.main` call. `run`'s prompt URL is now `../../prompt.md`. `scripts/protect-source.sh` now copies `src/` recursively (it used to copy `src/*.ts` only), and the workflow test checks that module files get staged too.

## Lint plugins

- New devDependencies: `eslint-plugin-explicit-types@^0.6.1` and `eslint-plugin-import-structure@^0.10.2`, both in `jsPlugins`. The lockfile comes from a real `npm install`.
- Enabled configs: `importStructure.configs.modules`, `explicitTypes.configs.concrete`, `explicitTypes.configs.absence`.
- **explicit-types `naming` is off** (the other app repos turn it on). Its `upper-snake-string-unions` and `no-upper-snake-object-keys` rules fire on wire tokens this repo doesn't choose: profile types `"claude" | "codex" | "opencode"` from `profiles.json`, failure reasons posted to Gitea, Gitea's `"new" | "old"` side, and environment variable names such as `PATH`. Satisfying them would change behavior or need opt-outs. This is logged as an open question for the user.

Lint fixes, all type-level:
- `Pick<BotProfile, "type" | "model">` became a named `ProfileIdentity` interface that `BotProfile`, `ProfileFailure`, and `RuntimeProfile` extend. `RuntimeOutcome` is now `RuntimeSuccess | RuntimeFailure`.
- Inline object types became named interfaces.
- `Record<string, string>` env maps became `NodeJS.ProcessEnv`. `JsonObject` and the verdict table became `NodeJS.Dict<…>`.
- `T | undefined` locals and returns became `T | null` with matching checks. `typeof fetch` became a `Fetcher` type.
- Claude's result fields are held in camelCase (`isError`, `apiErrorStatus`) after parsing, because `id-match` rejects snake_case interface members.
- Duplicate import sources are merged (`import-structure/no-duplicate-import-source`).

## Verification

- `vp check`: clean.
- `vp test`: 61 passed and 5 skipped as a normal user. All 66 passed as root in `node:24-bookworm`.
- Each phase (`node src/<phase>/index.ts`) run from a `protect-source.sh` copy loads its full alias graph under Node.

-- **Size limits match Deno** (2026-10-17, replaces the 2026-10-16 "default
-  limits stay"): repos behave as they did on Deno. bot-agents ran `deno lint`
-  with no config, so it had no size or complexity limit, and every Oxlint

-  anywhere without asking the user.
-- **`vite.config.ts` names no rule.** Every rule id, built-in ones included,
-  lives in `configs.project` of `scripts/project-lint.ts`
-  ([[project-lint-plugin]]). `vite.config.ts` only spreads configs.
-- **Published plugins are consumed through their configs**: ESLint flat config
-  uses `plugin.configs.<name>`; Oxlint lists the package in `jsPlugins` and
-  spreads `plugin.configs.<name>.rules`, since Oxlint plugins carry no configs.
-  Use the configs equivalent to what the repo enabled under Deno.
-- **`maxWarnings: 0`** keeps Deno's "every diagnostic fails" behaviour.
-- **`ignorePatterns`** is only for generated files (compiled output, codegen).
-  Hand-written code is never ignored.
-- **No lint disable comments**: [[lint-no-disable-comments]].
-- **Parity:** [[lint-parity-never-shrinks]]. **Naming:** [[naming-id-match]].
-- Don't add a second import sorter; the import-structure plugin's
-  `enforce-import-order` is the only one, and Oxfmt's `sortImports` stays off.
-
-`perf` came last: in the template it flagged nine `.includes` on constant
-arrays, fixed as `ReadonlySet` + `.has()` rather than by turning a rule off.
-That is the expected response to any new rule: change the code.

+description: Lint config shape: every non-nursery Oxlint category on, plugins via `all`, a blacklist of offs in configs.project, per-file exceptions only in projectOverrides, ignorePatterns only for generated output
+---
+
+Policy (2026-10-19): a blacklist, not a whitelist. Replaces the older
+category-subset and "no overrides" notes.
+
+- **Categories:** `correctness`, `suspicious`, `pedantic`, `perf`, `style`,
+  `restriction` at `error`. `nursery` stays off (no line for it).
+- **Plugins** are enabled whole through their `all` config
+  (`explicitTypes.configs.all.rules`, `importStructure.configs.all.rules`).
+- **Blacklist:** repo-wide offs and option tweaks live in
+  `projectLint.configs.project.rules` in `scripts/project-lint.ts`, spread
+  last in `rules`, each with a one-line reason. Never re-list a rule a
+  category already turns on. bot-agents runs on Node everywhere, so
+  `import/no-nodejs-modules`, `unicorn/no-process-exit`, and `no-console` are
+  off repo-wide.
+- **Per-file exceptions** only via `projectOverrides`, the whole `overrides`
+  array exported from `scripts/project-lint.ts`: the Node code entry
+  (`vite.config.ts`, `scripts/**`, `nodeRules`) first, then one entry per
+  exception with a why-comment. `vite.config.ts` has exactly
+  `overrides: projectOverrides`.
+- **No `allowFiles`** options in custom rules, and no disable comments
+  ([[lint-no-disable-comments]]).
+- **`ignorePatterns`** only for generated or build output, never hand-written
+  code. A hand-written file is linted, with override entries for only what it
+  legitimately breaks. bot-agents has no generated code, so none.
+- **Precedence:** categories < `rules` (a later spread wins) < `overrides` (a
+  later entry wins).
+- Size and complexity limits (`complexity`, `max-lines`, ...) are set to the
+  smallest value the current code passes.
+
+```ts
+// scripts/project-lint.ts
+export const projectOverrides: OxlintOverride[] = [
+  { files: ["vite.config.ts", "scripts/**"], rules: nodeRules },
+  // Why: src/example.ts must ... (a per-file exception, if one is ever needed)
+  // { files: ["src/example.ts"], rules: { "some-rule": "off" } },
+];

+  ...explicitTypes.configs.all.rules,
+  ...importStructure.configs.all.rules,
+  ...projectLint.configs.project.rules,
+},
+overrides: projectOverrides,
+```
+
+A new category hit is fixed in the code; an off or exception is added only
+for a real collision or churn, with its reason. Rules: [[project-lint-plugin]].
