Refresh tool category docs

[abhinavgautam01]

Closes #44.

Summary

Refreshes the generated README tool list so detection-only libraries are shown under a separate Library section instead of being mixed into Build.

Also updates CONTRIBUTING.md to document the current category set, including library, codegen, database, infrastructure, monorepo, environment, i18n, release and coverage.

Validation

go test ./...
go run ./cmd/brief list -readme tools | rg '^\*\*(Build|Library):'

The CONTRIBUTING.md table looks right and matches report.CategoryOrder.

The README block is generated though, and it's gone stale since #94 merged ten more library defs. Main now produces 534 tool definitions (this PR has 524) and the Library line is missing Busboy, Celery, Fabric, JDOM, Laravel Sanctum, Spring Security, Tera, Velocity, cross-spawn and dom4j.

Could you rebase on main and re-run go run ./cmd/brief list -readme tools to refresh the block between the brief:tools:start/end markers? After that this is good to go.

Thanks, fixed.

Rebased this branch onto current main and refreshed the generated README block with go run ./cmd/brief list -readme tools.

The README now reports 534 tool definitions and the Library section includes the ten definitions merged in #94: Busboy, Celery, Fabric, JDOM, Laravel Sanctum, Spring Security, Tera, Velocity, cross-spawn and dom4j.
