fix(process): reconcile canon and hints with the pipeline after #707–#730 (#748)

Five places still described the pipeline as it was before code that is
already in dev:

- the S3 hint of the task packet told the author to push the branch, while
  the spec lives in the issue body (§2.3, #517) and nothing is pushed
  before S5 (§11.8);
- process-gate printed «FAIL п.9 Gates: light» for a trailer nobody writes
  or reads, while §10.2 item 9 is the unimplemented release:prerelease
  verdict check. The check is removed; a contract test ties every RULES key
  to an implemented item of §10.2 and every finding number to a RULES key;
- §10.4 item 4 demanded a heredoc in run:, while #723/#730 and their tests
  demand the opposite: commit messages echo line by line into a file,
  comment and summary texts come from code;
- the ship merge comment, AUTHOR.md, REVIEWER.md and AGENTS.md named only
  the pre-beta document, though since #727 the night reads ship code first;
- the nightly publication committed «docs: ship review for nightly …
  перед бетой» with the beta step's Issue: #696. It now has its own
  subject (the document name), body and Issue: #727; the beta message is
  unchanged.

The browser-guard inventory note still said growth above 200 fails
mutation-gate --check; since #699 it is a guideline and --check warns. Its
counts now match the inventory: 205, lifecycle 90.

Issue: #748
