feat(mcp): hydrate GitHub source content - #1
Merged
Conversation
OpenSpec proposal/design/spec/tasks, Superpowers Design Doc, and implementation plan for on-demand GitHub source-content hydration.
QueryRepoWithSource truncated the result set to max_candidates when source_content was enabled, silently dropping structural matches beyond the limit. Return every matched node instead, hydrating only the first max_candidates and marking the rest "skipped", matching get_context's enrichment behavior so opting into source content never hides results.
