Publish Claude Code source snapshot from a single baseline commit

Squash the imported source snapshot and follow-up documentation history
into one root commit so the archive starts from a single coherent state.

Constraint: Repository intentionally tracks an analyzed Claude Code source snapshot
Constraint: Author and committer must be instructkr <no-contact@instruct.kr>
Rejected: Preserve the four-step import/docs history | user explicitly requested one squashed commit
Confidence: high
Scope-risk: broad
Reversibility: clean
Directive: Keep future analysis and refactor commits separate from this archive baseline
Tested: git status clean; local history rewritten to one commit; force-pushed main to origin and instructkr
Not-tested: Fresh clone verification after push
