refactor: rename pack command to build

[pavelanni]

Summary

• Rename skillctl pack to skillctl build to align with Docker/Podman conventions (build, push, pull, inspect)
• Rename all internal types: PackOptions → BuildOptions, PackBundle → BuildBundle, etc.
• Update user-facing docs (README, CLAUDE.md, deploy/README, landing page)
• Design docs and historical plans left unchanged as records

Test plan

• go build ./... compiles cleanly
• go test ./... all pass
• make lint zero issues
• Verify bin/skillctl build examples/hello-world/ works end-to-end

📝 Walkthrough

Walkthrough

The pull request refactors terminology across the codebase, renaming the OCI packaging operation from "pack" to "build." This affects CLI commands, exported API methods/types, documentation, and test suite references, while preserving all underlying functionality and logic.

Changes

Cohort / File(s)	Summary
Documentation Updates README.md, CLAUDE.md, deploy/README.md, docs/index.html	Updated workflow descriptions, command examples, and module documentation to use "build" instead of "pack" terminology. Changes are primarily in comments, section titles, and command references.
CLI Implementation internal/cli/build.go, internal/cli/root.go	Renamed CLI subcommand and dispatch functions from pack to build. Updated help text, function names (runPack → runBuild), method calls (Pack → Build), and option types (PackOptions → BuildOptions) throughout the command implementation.
Core OCI Package API pkg/oci/build.go, pkg/oci/bundle.go, pkg/oci/client.go	Renamed exported types and methods: Pack → Build, PackBundle → BuildBundle, PackOptions → BuildOptions, BundlePackOptions → BundleBuildOptions. Method signatures and field names updated while preserving parameter order and return types.
Test Suite pkg/oci/oci_test.go, pkg/oci/bundle_test.go	Updated test function names and method calls to match new API naming. Replaced all client.Pack calls with client.Build, client.PackBundle with client.BuildBundle, and updated error message assertions to reference the new method names.
