Agent Plugins 0.14.12

Skills that start from what a repository already has, and plans that say what the other host needs.

• ess:init checks a specification that is already there first: it runs ess specify validate and
  the repository's own conformance command, reports the counts, and recommends
  ess:testing-conformance when the suite is green. (#32)
• Every b10x init or upgrade command a plugin prints names --host, with the wording of
  b10x:init; agentplugins-check refuses one that does not. (#32)
• ess:testing-conformance shows a TypeScript refusal recorder (err.cause === ErrUnsupported)
  beside the Go one. (#32)
• The ESS syntax reference lists the structured predicate forms (all, any, not, none, map
  operators, quantifiers, .count) that when, invariants and filter accept, no longer tells
  authors to split "A or B" into two views, and names the forms synthesize still refuses.

• b10x init/upgrade --host <one> says what a plan for the other host would do when it holds
  Beyond10x installs — action count and legacy, missing and marketplace changes — and prints
  "Nothing to change for ." while that plan has changes. When the other host is current, one
  line says so. (#33)
