feat: write leafs incrementally without rebuilding the graph.

Ladybug 0.19 stays FTS/HNSW queryable on MERGE of new ids; DROP INDEX
was the fatal path. bin/brain/add.go and POST /ingest land facts+info
in one transaction so watch/mail/git can become leafs now (Gitea #14).

-  Use https://github.com/duckdb/duckdb-go in-process for columnar analytics
-  (quantiles, GROUP BY, JSON/CSV/Parquet/JSONL scans) when that is faster than
-  nested Go loops. Not Ladybug. Not the web-search sqlite cache. Use when
-  aggregating samples, counting JSONL, or SQL over tabular files.

-Use https://github.com/duckdb/duckdb-go where it makes sense to get better performance in code.
-
-In-process DuckDB (`internal/duckstats`, `database/sql` driver `duckdb`).
-Vectorized SQL over tables, JSONL, CSV, Parquet. CGO with bundled libs
-(linux/darwin amd64/arm64). Links with **gcc/g++** (libstdc++), not Zig.
-D21 Zig (`bin/cgo/zcc`) is Ladybug/tokenizers only. After
-`eval "$(bin/cgo/zig env)"`:
-
-```bash
-CC=gcc CXX=g++ CGO_CFLAGS= CGO_LDFLAGS= ./bin/qa/stats.go <<< '[1,2,3,4,5]'
-CC=gcc CXX=g++ CGO_CFLAGS= CGO_LDFLAGS= go test ./internal/duckstats

-| Store | Job |

-| Ladybug | graph + FTS + HNSW (facts/info) |
-| modernc sqlite | web-search KV cache + throttle |
-| duckdb-go | OLAP: quantiles, counts, scans of many rows/files |
-| mikefarah/yq | small YAML/JSON/XML/CSV/TOML/HCL slice, not bulk |

-Do not open Ladybug through DuckDB. Do not put secrets or client PII into
-DuckDB files under the repo.
