Integrate local skills CLI after mainline drift

PR #1162 adds local skills discovery and CLI management. Current main already changed startup heap handling and knowledge graph corruption-test isolation, so the merge keeps the skills CLI fast-path while preserving main's unconditional NODE_OPTIONS heap guard and searches corruption artifacts from the resolved Orama path.

Constraint: Resolve PR #1162 against main at f102b60 without dropping either the skills CLI bypass or the mainline heap/knowledge-graph fixes.

Rejected: Keep the PR's older CCR-only heap guard | main intentionally expanded the heap guard for local long-running agents.

Rejected: Search corrupted Orama files from a broad config root | the resolved persistence path is the authoritative location under redirected config state.

Confidence: high

Scope-risk: moderate

Directive: Keep skills management commands available before provider startup validation so broken provider config does not block local skills inspection.
