Add four new infrastructure packages with CLI commands: - pkg/config: layered configuration (defaults → file → env → flags) - pkg/crypt: crypto primitives (Argon2id, AES-GCM, ChaCha20, HMAC, checksums) - pkg/plugin: plugin system with GitHub-based install/update/remove - pkg/collect: collection subsystem (GitHub, BitcoinTalk, market, papers, excavate) Fix all golangci-lint issues across the entire codebase (~100 errcheck, staticcheck SA1012/SA1019/ST1005, unused, ineffassign fixes) so that `core go qa` passes with 0 issues. Closes #167, #168, #170, #250, #251, #252, #253, #254, #255, #256 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
