* refactor(duckdb): extract shared json-safe bigint helper
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* feat(duckdb): add and register the duckdb primary connector
Add KtxDuckDbDialect, KtxDuckDbScanConnector (local file-backed, read-only,
never-create, main-schema introspection via information_schema and
duckdb_constraints() for foreign keys), and register the duckdb driver across
the dialect factory, driver registry, connection-type enum, warehouse descriptor,
config schema, scan normalization, connection test drivers, and status display.

* feat(duckdb): route live-database ingest through the DuckDB connector
Add the DuckDB live-database introspection bridge and dispatch duckdb
connections to it in local-adapters, matching the SQLite path. Repoint the
config-rejection test off duckdb (now a valid driver) onto the no-driver case.

* feat(duckdb): add duckdb to the setup database flow
Offer DuckDB in the interactive checklist and via ktx setup --database duckdb,
with a file-path prompt and duckdb-local default connection id, parallel to SQLite.

* feat(duckdb): attach native duckdb files in federation
Native .duckdb members ATTACH with (READ_ONLY) and no TYPE/INSTALL/LOAD, since
the duckdb format needs no extension. attachTypeForDriver returns null for the
native case; buildAttachStatements builds load statements from non-null types
only and emits a conditional ATTACH clause.

* docs(duckdb): document the duckdb primary-source connector
Add a DuckDB section to the primary-sources integration page (config, read-only
never-create behavior, main-schema scope, federation) and update the
supported-driver assertion in dialects.test.ts to include duckdb.

* fix(duckdb): use single-namespace display shape for main-only refs
DuckDB v1 introspects the main schema and sets db=null on every table, so its
display refs are single-namespace like SQLite. The ansi shape emitted a 1-part
table display it then refused to parse, breaking column-level display resolution.
Switch the dialect to the sqlite display shape and add a round-trip test plus a
composite-foreign-key test that were missing.

* refactor(duckdb): resolve connector dialect via getDialectForDriver
Route the connector's dialect through the shared factory like every other
connector, now that duckdb is registered. Single construction path.

* fix(duckdb): skip schema picker for single-file duckdb setup
DuckDB is a single-file, single-namespace ('main') database like SQLite,
but the setup scope step only skipped the schema picker for sqlite. DuckDB
fell into the multi-schema path with an empty schema list, rendering a
broken picker ("No matches found" for main). Extend the file-based-driver
early-return to cover duckdb so it ingests every table directly.

* refactor(duckdb): reuse shared config helper and derive scope skip
Route duckdb path resolution through the shared resolveStringReference
helper instead of a local third copy of env:/file: handling. Derive the
setup scope-picker skip from SCOPE_DISCOVERY_SPECS membership rather than
a hardcoded sqlite/duckdb driver list.

* test(duckdb): use a genuinely unknown driver in the rejection test
The merged "rejects unknown drivers" test used `driver: duckdb` as its
unknown-driver stand-in, which stopped being unknown once this branch
added the duckdb connector. Switch to `nonsense` so it again exercises
the unsupported-driver config error.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* test(duckdb): cover dialect, connector, and live-introspection branches
Codecov flagged uncovered branches as dead code; all are real connector,
dialect, and live-ingest behavior. Add unit tests instead of removing them.
- dialect: precedence ladder, sample/clause builders, profiling expressions
- connector: url/env config forms, error throws, never-create guard,
cardinality cap branches, table-scope empty/non-empty paths
- live-introspection: full-schema and table-scope extraction
Functions 100%, lines ~99% across the duckdb connector dir.

* docs: add DuckDB to supported-driver references
The DuckDB connector PR documented the connector itself but left the
scattered supported-driver enumerations stale. Add duckdb to the
federation concept page (participation table, activation, table naming,
limitations), the ktx setup CLI reference, the ktx.yaml warehouse-driver
table, the primary-sources field reference, and the quickstart driver
list (which also restores the missing ClickHouse entry).
