Move the read-only inspection verbs — stat, log, leaves, timeline, branch, tag, info, ls, cat, artifact, annotate — together with the name-resolution and rendering helpers private to them out of src/main.zig into the new src/cmd/history.zig, mirroring the S2 sync and S3 tracking extractions.

Pure behaviour-preserving move: every relocated declaration is byte-identical to its main.zig source. The only changes are the new import prologue and the pub forced on the eleven dispatch-called handlers. Helpers shared with the still-in-main checkout verbs (repoReadFail, openRepo, reasonOf, firstCommentLine, renderBranchList, lessByHash, mintControlArtifact, and the per-verb help strings) stay pub in main.zig and are aliased back in the prologue.

The extraction is non-contiguous: the checkout family — update, bisect, merge, revert, undo, redo, commit, amend — is interleaved among the moved verbs and is left exactly in place.

main.zig keeps the verb-dispatch switch, now calling cmd_history.runStat and its siblings; its test root imports the new file so the moved inline test keeps running. closed check-in: 8e2c31c8ba user: dmestas tags: s4-history
