The April 2026 IDX ownership PDF omits the zero-valued scrip column for
some holders, causing the parser to leave holdings_scripless/scrip as
empty strings. This broke normalize_ksei_row which called parse_id_number
on empty input.
Two-layer fix:
- Parser: pop_numeric_tail handles 2-column (missing scrip) rows by
defaulting scrip to "0"
- Normalizer: parse_id_number_or_zero backstop treats empty component
share fields as 0 while still requiring total_shares
Also includes AGENTS.md refresh, formatting cleanup (rustfmt), and
version bump to 0.2.2.

Add a compact parser fixture excerpted from the real 2026-03-10 IDX above1 lamp1 mutool stext output and assert the first live row still parses as expected.
This keeps the post-merge ownership parser coverage grounded in the supported above1 layout instead of relying only on synthetic line fixtures.
Refactor KSEI PDF parsing for the live above-1 holder-register layout, add IDX announcement discovery plus browser-impersonated PDF fetches, and update the ownership docs to mark Batch 1 complete and scope Batch 2 around above1 hardening and unsupported legacy inputs.
