fix(daemon/specs): strip trailing-ws + reconcile advisor.lead role.md with deprecation curation

Forward-fix #2 on Phase 05d guard-3 narrow re-verify at 0f92966.

(1) Whitespace strip: openrig-architect SKILL.md line 48 had 3 trailing
    spaces. git diff --check now clean across the worktree.

(2) Role/profile reconciliation: advisor.lead/guidance/role.md still
    referenced `mental-model-ha` as the compaction-survival skill even
    though the prior forward-fix dropped it from the profile (per the
    2026-05-10 2f56163 curation that deprecated the bundled copy).
    Resolution: replace the bundled-skill reference with an inline
    compaction-survival discipline note that names the durable
    substrate primitives (`rig whoami` / `rig transcript` / `rig
    queue`) and leaves a hook for operator-installed richer skills.

    Chose this over packaging mental-model-ha as the 6th skill because
    spec-library-starters.test.ts asserts BOTH (a) shared pool MUST
    NOT contain mental-model-ha AND (b) public builtin agent profiles
    MUST NOT reference it — the curation is binding, not opportunistic.

(3) Test gate widened: the "public builtin agent profiles do not
    reference deprecated HA skill" check previously walked only
    AGENT_SPECS (which excluded kernel agents). Kernel agents are
    now built-in surface and must respect the same curation, so the
    test now also walks the 3 kernel agent specs. Caught at Phase 05d
    forward-fix #2 when advisor.lead reintroduced the reference.

Tests: kernel-boot 16/16 + kernel-rig-spec-validate 8/8 + spec-
library-starters 18/18 all green. git diff --check clean.
