fix(sync): guard putPage 0-row RETURNING + reclassify sync failure copy (#2189)

Root cause of #2189's opaque per-file crash: putPage's INSERT … ON CONFLICT
DO UPDATE … RETURNING can yield 0 rows when brain-local DB state (e.g. a
BEFORE trigger) suppresses the write, and rowToPage(rows[0]) then died with
"undefined is not an object (evaluating 'row.deleted_at')". Both engines now
throw a descriptive error naming the slug + source_id so the failure is
diagnosable per-file instead of an anonymous TypeError.

Also lands the salvageable parts of community PR #2586 (takeover): the
"failed to parse / fix the frontmatter" copy misclassified runtime import
errors as YAML problems — reworded to "failed to import" — plus its
first-code-sync PGLite smoke test.

New regression test reproduces the exact 0-row RETURNING state via a
suppressing trigger: fails pre-fix with the reported crash signature,
passes with the guard.
