v0.2.12

[0.2.12] - 2026-09-09

Fixed

• Generate the git-backend fork timestamp as strictly 14 digits: lib/engine.mjs stripped only - and : from toISOString() before slicing 14 characters, so the ISO T survived (20260909T13523), forkFileName's /^\d{14}$/ check failed, and every git-backend conflict fork silently fell back to the epoch stamp 19700101000000. The stamp now removes -, : and T exactly like lib/encrypted.mjs, yielding a real yyyyMMddHHmmss UTC stamp; the encrypted backend was already correct and no other behavior changes. Regression tests assert a 14-digit non-epoch stamp on a real fork path plus the acceptance/fallback contract in test/paths.test.mjs.
