feat(trail): scaffold default runners when tune runs in a repo with none

`entire trail tune` now doubles as onboarding. In a repo with no .entire/runners/*.json, it offers to create the default set first (interactive confirmation, or --yes for non-interactive/CI runs) and then tailors them as usual — so a single `tune --run` bootstraps a repo end to end.
The defaults are embedded in the binary (new runnerdefaults package: the 7 canonical runners with correct contract fields + generic templates) rather than generated by the model, so the structural schema (output adapters, result types, runtime/automation) is always valid and only the templates get tailored. Non-interactive runs without --yes error rather than silently scaffolding.
Tests cover the embedded set's validity/completeness and the create/no-op paths of ensureRunnersPresent.

// Package runnerdefaults embeds the canonical generic trail runner configs, so
// \`entire trail tune\` can scaffold them into a repository that has none yet.
// These are the structural contract (output adapters, result types, runtime)
// plus generic prompt templates; tune tailors the templates to the repo.
