pnpm 10.33.0 added `dedupePeers` to the lockfile settings block. The `LockfileSettings` struct was missing this field (and `peersSuffixMaxLength`), causing them to be silently dropped during deserialization. After `turbo prune --docker`, the pruned lockfile was missing these settings, which made `pnpm install --frozen-lockfile` fail with `ERR_PNPM_LOCKFILE_CONFIG_MISMATCH`. This commit: 1. Adds explicit `dedupe_peers` and `peers_suffix_max_length` fields 2. Adds a `#[serde(flatten)]` catch-all map (matching the existing pattern in `PackageSnapshot`) so any future pnpm settings are preserved through round-trips 3. Adds tests for both the specific field and the generic catch-all Fixes vercel#12442

Hey, thanks for this addition.
I've removed the catch-all behavior because we always want to make sure we handle any configurations that folks are using. It's easier for us to handle and make sure we handle a set of known keys rather than allow for any unknown behaviors.
