Adds the kb-app crate (§7) as the single facade between UI crates
(kb-cli / kb-tui / kb-desktop) and the rest of the workspace. Public
surface mirrors the task spec exactly:
- init_workspace(force) — XDG dir creation + config.toml seed; idempotent
unless force=true. Honors XDG envs and tilde-expands the workspace
root to $HOME/KnowledgeBase.
- doctor() — emits a doctor.v1 report with config_loaded +
data_dir_writable checks; downstream checks land in later phases.
- ingest / list_docs / inspect_doc / inspect_chunk / search / ask —
bail!("not yet wired (P<n>-<i>)") so kb-cli surfaces exit code 2
cleanly per §10.
- AskOpts + DoctorReport + DoctorCheck.
- doctor_signal::{DoctorUnhealthy, RefusalSignal, NoHitSignal} —
signal types the CLI downcasts on for §10 exit-code mapping.
- logging::init() — daily-rolling file appender at
$XDG_STATE_HOME/kb/logs/kb.log, plus stderr-fallback EnvFilter.

Adds the kb-config crate per design §6. Provides the frozen Config
schema (§6.4) with serde + toml round-trip, defaults() that exactly
match the reference values (e.g. score_gate=0.30, target_tokens=500,
embedding.dimensions=384, rrf_k=60), and XDG path resolvers that honor
XDG_CONFIG_HOME / XDG_DATA_HOME / XDG_CACHE_HOME / XDG_STATE_HOME.
Layer order in load(): defaults → file → env (KB_<SECTION>_<KEY>);
CLI overrides apply later in kb-cli. Env mapping covers the keys
needed by P0 smoke tests; the rest land as their config sections wire
up.
5 unit tests cover serde round-trip, defaults pinned to design,
KB_RAG_SCORE_GATE / KB_SEARCH_DEFAULT_K env override, and
XDG_CONFIG_HOME handling.

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.
