fix: patch flatted CVE-2026-32141 unbounded recursion DoS (#27)

Resolves Dependabot alert
[#78](https://github.com/BYK/superset/security/dependabot/78).

## Summary

Adds a pnpm override for `flatted >=3.4.0` to fix
[CVE-2026-32141](https://nvd.nist.gov/vuln/detail/CVE-2026-32141) (HIGH,
CVSS 7.5) — an unbounded recursion DoS in `flatted.parse()` that can
crash Node.js with a single crafted payload.

## Details

The transitive dependency chain is:
```
eslint → file-entry-cache → flat-cache@4.0.1 → flatted@3.3.4 (vulnerable)
```

`flat-cache@4.0.1` declares `flatted@^3.2.9`, which is semver-compatible
with `3.4.0+`, so the override safely forces resolution to the patched
version (`3.4.2`) without breaking the dependency contract. This follows
the existing override pattern used for `serialize-javascript` and
`diff`.

## Changes

- **package.json**: Added `"flatted": ">=3.4.0"` to `pnpm.overrides`
- **pnpm-lock.yaml**: Regenerated (`flatted@3.3.4` → `flatted@3.4.2`)

All 38 tests pass ✅

 ### Gotcha
 
-<!-- lore:019cc484-f0e1-7016-a851-177fb9ad2cc4 -->
-* **AGENTS.md must be excluded from markdown linters**: AGENTS.md is auto-managed by lore and uses \`\*\` list markers and long lines that violate typical remark-lint rules (unordered-list-marker-style, maximum-line-length). When a project uses remark with \`--frail\` (warnings become errors), AGENTS.md will fail CI. Fix: add \`AGENTS.md\` to \`.remarkignore\`. This applies to any lore-managed project with markdown linting.

-* **Consola prompt cancel returns truthy Symbol, not false**: When a user cancels a \`consola\` / \`@clack/prompts\` confirmation prompt (Ctrl+C), the return value is \`Symbol(clack:cancel)\`, not \`false\`. Since Symbols are truthy in JavaScript, checking \`!confirmed\` will be \`false\` and the code falls through as if the user confirmed. Fix: use \`confirmed !== true\` (strict equality) instead of \`!confirmed\` to correctly handle cancel, false, and any other non-true values.

 * **Craft v2 GitHub App must be installed per-repo**: The Craft v2 release/publish workflows use \`actions/create-github-app-token@v1\` which requires the GitHub App to be installed on the specific repository. If the app is configured for "Only select repositories", adding a new repo to the Craft pipeline requires manually adding it at GitHub Settings → Installations → \[App] → Configure. The \`APP\_ID\` variable and \`APP\_PRIVATE\_KEY\` secret are set in the \`production\` environment, not at repo level. Symptom: 404 on \`GET /repos/{owner}/{repo}/installation\`.

-* **Zod z.coerce.number() converts null to 0 silently**: Zod gotchas in this codebase: (1) \`z.coerce.number()\` passes input through \`Number()\`, so \`null\` silently becomes \`0\`. Be aware if \`null\` vs \`0\` distinction matters. (2) Zod v4 \`.default({})\` short-circuits — it returns the default value without parsing through inner schema defaults. So \`.object({ enabled: z.boolean().default(true) }).default({})\` returns \`{}\`, not \`{ enabled: true }\`. Fix: provide fully-populated default objects. This affected nested config sections in src/config.ts during the v3→v4 upgrade.
