fix(typegen): preserve fmodata customizations with clearOldFiles

[eluce2]

Note

Medium Risk
Changes the clearOldFiles behavior to delete files after regeneration via a recursive cleanup, which could remove unexpected entries if the output path is misconfigured, but is otherwise localized to type generation output.

Overview
Fixes fmodata type generation so clearOldFiles no longer nukes the output directory before merging with existing files; existing schemas are now always parsed so field-level customizations (e.g. validators) are preserved.

When clearOldFiles is enabled, stale files/directories are now removed after generation by tracking regenerated files (including index.ts) and deleting any other entries in the output tree. Adds an e2e test covering customization preservation plus stale file cleanup, and includes a patch changeset.
