feat(git-sync): phase 3 — PUSH reads native gitmost_id + derives title/parent from path

Browse Source 
PUSH now consumes the native-Obsidian format end-to-end:
- identity from the gitmost_id frontmatter (parsePageFile), not docmost:meta;
- title from the FILENAME, parentPageId from the enclosing folder's folder-note
  (parentFolderFile is now FOLDER-NOTE aware: a child's parent is dir/dir.md, and
  a folder-note's own parent is one level up), spaceId from the run (every vault
  file belongs to the vault's space);
- CREATE derives title/parent/space from path + run and writes the assigned
  pageId back as gitmost_id frontmatter (serializePageFile);
- UPDATE pushes the STRIPPED body (current + 3-way-merge base), so the frontmatter
  never leaks into Docmost content; the loop-guard hashes the body.

The PURE delete-sensitive classifier (computePushActions/classifyRenameMoves) is
UNCHANGED — only the injected IO resolvers (metaAt, parent, create write-back)
switched source. nativeMeta always carries the run spaceId, so the legacy
'create-without-spaceId' skip no longer fires through runPush.

Tests rewritten to native fixtures + folder-note parent paths; the noop case is
now a child under a renamed parent folder (filename=title, so a path-only-noop
needs an ancestor rename). parentFolderFile tests cover leaf/folder-note/nested/
dotted. 612 engine tests green; engine rebuilt.
