AI Summary

Optimizes build performance by reducing redundant writes to the `i18n.lock` file and skipping full-file deduplication during load.

Key Highlights

Significant speedup for projects with many bucket paths and locales.
`i18n.lock` is now written once per pattern rather than per locale/task.
Lockfile loading skips full deduplication unless the file is malformed.
Plain YAML parse is attempted first to avoid unnecessary re-serialization.

New Features

Performance optimization
Optimized lockfile handling

### Patch Changes

- [#2191](https://github.com/lingodotdev/lingo.dev/pull/2191) [`fa77c24`](https://github.com/lingodotdev/lingo.dev/commit/fa77c24701e19be876f746edbc22a188f0812b5a) Thanks [@cherkanovart](https://github.com/cherkanovart)! - Speed up `lingo.dev run` on projects with many bucket paths and locales.

  Every translation task rewrote the whole `i18n.lock`, so a run performed
  `patterns × locales` full read-modify-write cycles to persist `patterns`
  sections. Since every target locale of a bucket path derives its checksums from
  the same source data, all but the first write per pattern stored identical
  bytes. A run now writes a pattern's section once, and those writes are
  serialized against each other.

  Loading the lockfile also ran the deduplication pass — a full CST parse plus a
  re-serialization of the entire file — on every load. Deduplication only repairs
  a hand-merged lockfile, which is exactly the case `YAML.parse` rejects, so the
  load now tries the plain parse first and falls back to the repair path only when
  that fails. Malformed and hand-merged lockfiles keep loading exactly as before.

  The contents of `i18n.lock` are unchanged.
