REUSE-WP-0018-T05: ecosystem rollout convention drafted and proposed

Gate cleared: WP-0017 finished 2026-07-07, federated.yaml now carries 61
real capabilities (was 24). Dogfooded immediately -- plan-check against
'unified interface for issue tracking across Gitea GitHub GitLab' now
correctly returns extend/capability.infotech.issue-tracking instead of new.

Drafted the query-before-build convention in .claude/rules/workplan-convention.md
(gitignored, local -- propagation happens via the custodian rules-template
mechanism, not a reuse-surface git commit). Sent State Hub message to
custodian-agent proposing it be added to the shared template
(13cecd08-14e8-46d9-880c-65b8fef857cb).

Added reuse_check frontmatter to REUSE-WP-0018 and REUSE-WP-0019 themselves
as the reference implementation, both dogfooded for real against the live
federated index (both correctly verdict 'new').

REUSE-WP-0018 is now done except T03 (LLM semantic rerank), deferred
pending a running llm-connect instance. Updated IntentScopeGapAnalysis.md
priority 29 accordingly.
