kevinveenbirkenbachandClaude Opus 5 a423bde6cc refactor(mcp): unify client entrypoints and read provider tokens through one lookup
Every MCP role keeps its task tree under tasks/utils/ without numeric
prefixes, so a caller can reach any of them through include_role
tasks_from. utils/roles/mapping.py holds that path as the single source.

Ansible resolves a relative include against the including file's own
directory when that file was reached by path, but against tasks/ when it
was reached through tasks_from. The same file therefore loaded from its
own role and failed from a caller using tasks_from. Every nested include
now names {{ role_path }}/tasks/utils/..., which holds under both bases,
and a lint walks each tasks_from entrypoint transitively to keep it so.
The exec-gating lint learns the same form, otherwise it loses the include
chain and reports inherited IS_STACK_HOST gates as missing.

The expression resolving a provider's stored token appeared eighteen
times. plugins/lookup/mcp_credential.py replaces it, and mcp_probe_owner
disappears from eight roles: it was only ever a step towards the bearer
and no probe read it.

The Hermes and OpenClaw probes stop aborting the play while it is still
running. Roles deploy in dependency order, so a client probing during its
own role can run before a provider exists at all, and failing there
prevents that provider from ever deploying. The verdict moves to the
reconciliation pass, gated on MCP_RECONCILE_STRICT, which the reconciler
sets and group_vars declares so the readers need no default.

The sys-svc-mcp-reconcile role is added here; wiring it into a stage is a
separate change.
