- Cargo.toml: remove `thiserror` from kb-config, kb-parse-types, kb-app
(unused — none of those crates' src trees reference thiserror; CoreError
in kb-core is the only consumer).
- kb-config keeps the `kb-core` dep with a one-line comment marking
CoreError reserved for P1-* config-error wiring per the review thread.
- ids.rs: switch `validate_hex32` from a hand-rolled `matches!` byte range
to `is_ascii_hexdigit()` so the hex check is the canonical idiom (and
satisfies `clippy::manual_is_ascii_check` under `-D warnings`).

Adds the kb-parse-types crate per design §3.7b. Depends only on kb-core
+ serde/thiserror — never on parser libraries. Defines:
- ParsedBlock + ParsedBlockKind + ParsedPayload (8 variants matching
Block variants in kb-core).
- Warning + WarningKind for parser diagnostics.
- Forward-declared ParsedImageRegion / ParsedPdfPage / ParsedAudioSegment
shells for P6/P7/P8.
`cargo tree -p kb-parse-types` shows only kb-core, serde, and thiserror.
