fix(lint): force-ignore output.ts from Biome type analysis (200k limit) (#1536)

## Problem

`Lint & Typecheck` fails on an internal Biome error, with no real lint
violation in the changed code:

```
src/lib/formatters/output.ts  project  INTERNAL
  ! Biome encountered an unusually large amount of types which exceeded the limit of 200,000.
```

`output.ts` imports valibot's `GenericSchema`, whose recursive generic
graph pushes Biome's project-mode type inference over its 200,000-type
ceiling — the **same internal Biome bug already handled for
`custom-ca.ts`** in this config (see the existing
`"!!src/lib/custom-ca.ts"` force-ignore).

It surfaces **non-deterministically**: `main` passes by a hair, but the
exact type count tips over on PR runners, so unrelated PRs fail this job
identically — e.g. #1499, #1501, and #1535. Re-running does not clear it
(deterministic per branch state).

## Fix

Force-ignore `src/lib/formatters/output.ts` the same way as
`custom-ca.ts`, until Biome raises/fixes the limit.

```jsonc
"!!src/lib/custom-ca.ts",
"!!src/lib/formatters/output.ts"
```

## Verification

`pnpm run lint` (the CI invocation) now passes:

```
Checked 1025 files in 3s. No fixes applied.   (exit 0)
```

Unblocks #1535 (and the other PRs above) once merged. Trade-off is the
same one already accepted for `custom-ca.ts`: `output.ts` (a leaf
formatter) is skipped by Biome; it stays covered by `tsc`.
