Package the reusable prompt collection under prompts/

HF-WP-0005. The prompts used to drive work across HelixForge repositories
existed only as text pasted between sessions. They are now Canned Prompt Format
v0.2 packages with declared inputs, parameters and output contracts.

Seven packages: repo-orient (merging "what is this repo about" with "what
should we do now" as a `depth` parameter), repo-register, repo-advance,
commit-sync, scope-audit, gap-workplan, session-close.

"Go on implement, please" is deliberately not packaged. It is conversational
continuation with no contract to declare, and packaging it would produce an
artifact whose only content is the word "continue".

Every one of these prompts assumed the operator's setup — the State Hub is a
read model, workplans originate as files and are never registered by hand, a
session closes with a progress event. That assumption is what made them
personal rather than reusable. helix/custodian-conventions states those rules
once as a fragment composed by every package, so they are versioned,
improvable in one place, and present for an agent that has never seen this
fleet.

helix/commit-sync-routine exists for a narrower reason. repo-advance first
composed the whole commit-sync package, which itself composes the conventions,
so the rendered prompt carried the conventions block twice — CPF inclusion does
not deduplicate, and a diamond dependency renders shared content once per path.
Factoring the routine out removes the diamond and is a better factoring
regardless. Recorded upstream as canned-prompts CANP-WP-0004-T03.

helix/session-close composes practice/pqrst-estimate, so the canonical PQRST
block is embedded verbatim. hall-of-helix CLOSING.md says the canonical prompt
still governs when you have no pqrst-practice checkout, without saying how it
reaches you; this is how. evals/pqrst-embedded.yaml fails if the canonical text
stops being embedded verbatim, rather than letting the package quietly become a
paraphrase.
