Snider f2bc912ebe feat: infrastructure packages and lint cleanup (#281)
* ci: consolidate duplicate workflows and merge CodeQL configs

Remove 17 duplicate workflow files that were split copies of the
combined originals. Each family (CI, CodeQL, Coverage, PR Build,
Alpha Release) had the same job duplicated across separate
push/pull_request/schedule/manual trigger files.

Merge codeql.yml and codescan.yml into a single codeql.yml with
a language matrix covering go, javascript-typescript, python,
and actions — matching the previous default setup coverage.

Remaining workflows (one per family):
- ci.yml (push + PR + manual)
- codeql.yml (push + PR + schedule, all languages)
- coverage.yml (push + PR + manual)
- alpha-release.yml (push + manual)
- pr-build.yml (PR + manual)
- release.yml (tag push)
- agent-verify.yml, auto-label.yml, auto-project.yml

* feat: add collect, config, crypt, plugin packages and fix all lint issues

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
