This directory vendors the Zig sqlite3 build package and SQLite 3.51.0 amalgamation sources used by nullclaw.

Why vendored:

• avoid runtime nested zip downloads during zig build
• make builds deterministic across environments where Zig zip temp handling fails (see issue #142)
• integrity is enforced by SHA-256 verification in the root build.zig when SQLite is enabled

Contents:

• build.zig and build.zig.zon based on allyourcodebase/sqlite3 and patched to library-only mode for nullclaw
• sqlite3.c, sqlite3.h, sqlite3ext.h from SQLite 3.51.0 amalgamation
