feat(manifest): reject [/] in extraction title (ingest-spec §4)

Ingest-spec §4 (ratified D1, commons bfa5a9b) requires a title to reject
`[` and `]` fail-fast at manifest load. The title is rendered verbatim into
the index link label and frontmatter (§5/§6), where a bracket would break
index-link and navigation parsing (method-spec §3 Step 1). The rule was
specced but unenforced: validation only checked single-line.

Satisfies the commons "Title link-safety" load-bearing §11 seam. Same
`manifest_schema` error code as the sibling single-line/max_rows rules;
parametrized cases added to test_manifest and test_error_codes.
