🏗️ refactor(kebab-app): consolidate PARSER_VERSION + clarify intent (fb-27)

Replace kebab-app's private `KEBAB_PARSE_MD_VERSION` literal with a
direct reference to `kebab_parse_md::PARSER_VERSION` so the parser
version cascade has a single source of truth (design §9 invariant).

Add maintenance comment on schema.rs WIRE_SCHEMAS const pointing to
docs/wire-schema/v1/ + kebab-cli wire helpers as the authoritative
sources to keep in sync.

Tighten open_existing doc comment to match the actual SQLITE_OPEN_READ_WRITE
flag (needed for WAL pragma application) — callers should still avoid
issuing mutations through this connection.
