fix(preamble): teach the model to prefer mcp__*__AskUserQuestion when registered

When a host launches Claude Code with --disallowedTools AskUserQuestion
(Conductor does this by default — verified via ps on the live conductor
claude process), the native AskUserQuestion tool is removed from the
model's tool registry. Skill templates that say "call AskUserQuestion"
silently fail in that environment: the model can't ask, the user never
sees the question, the skill auto-proceeds without input.

The fix is preamble guidance, not a skill-template change:

  generate-ask-user-format.ts: new "Tool resolution" section at the top
  of the AskUserQuestion Format block. Tells the model that
  "AskUserQuestion" can resolve to two tools at runtime — the host MCP
  variant (e.g. mcp__conductor__AskUserQuestion, registered when the
  host injects it) and the native tool — and to PREFER any
  mcp__*__AskUserQuestion variant. Same questions/options shape; same
  decision-brief format. If neither variant is callable, fall back to
  writing a "## Decisions to confirm" section into the plan file plus
  ExitPlanMode (the native plan-mode confirmation surfaces it). Never
  silently auto-decide.

  generate-completion-status.ts: the plan-mode-info block (preamble
  position 1) now explicitly notes that AskUserQuestion satisfies plan
  mode's end-of-turn requirement for "any variant" and points at the
  Tool resolution section for the fallback path.

This puts the resolution rule in front of every tier-≥2 skill via the
preamble, so plan-mode review skills (plan-ceo-review, plan-eng-review,
plan-design-review, plan-devex-review, autoplan, office-hours) all gain
the fix without per-template surgery.

Includes regenerated SKILL.md files for all 41 skills + the 3 host-ship
golden fixtures used by test/host-config.test.ts.
