feat: promote by explicit content sha + build Step Summary with copy-…

…paste promote commands (#4)

- promote <fn> --sha <64hex>: promote one explicit content sha (bypasses the
  catalog), validated 64-hex, refuses 'all'. Lets a promotion target the exact
  artifact a build run reported, no catalog round-trip.
- build --json-out <file>: write the build summary JSON array to a file so CI can
  render it deterministically (stdout stays the human view).
- Reusable build.yml: render a Step Summary per run - a table (function, outcome,
  content sha, dev key) plus, per function, the prod pin snippet and a ready-to-run
  'gh workflow run' promotion command. The promotion target is caller-supplied
  (promotion_repo / promotion_workflow / project inputs); the reusable workflow
  hardcodes no consumer or infra repo.

Bumps to 0.6.0. builder_version folds into the content hash, so this re-keys
artifacts on the next consumer rebuild (byte-identical zips, new keys).
