fix(workplans): adopt ADR-007 derived identifiers for unregistered records 
These workplans exist only in the retired local hub. Their random pre-ADR-007
identifiers are refused by C-06 as stale references, so they cannot be
registered. Deriving from the canonical record id takes no identity from
anything: central does not hold them and the old ids die with the cache.

Records central already holds were deliberately left untouched.

ESRC-WP-0003 — Metadata enrichment

Today ingestPdf only passes through caller-supplied title/uri/metadata. This workplan extracts intrinsic document metadata (PDF info dictionary, embedded XMP, page-derived signals like author/creation date/title) and folds it into the Document record without breaking the pure-over-bytes contract.

Enumerate available PDF metadata sources (info dict, XMP) via PDF.js and decide precedence vs. caller-supplied options (caller wins).

Implement extraction into a normalized metadata shape; keep it optional so minimal-metadata PDFs still ingest cleanly.
