Add four config-type preset rosters (general, coding, research, hybrid) with
exactly one orchestrator each using the claude runtime; worker agents use pi
with model_hint openai-codex/gpt-5.5:high. Extend `mosaic fleet init` with a
readline-based interactive wizard (AI-free) that prompts for preset selection
when no --profile is given and stdin is a TTY; falls back to "general" with a
note when non-interactive. Export parseInitProfile, resolvePresetFilename,
countOrchestrators, FLEET_PROFILES, and FleetProfile for testability. Add 24
new tests covering preset shape, sanitization, wizard TTY/non-TTY paths, and
R8 idempotency. All gates green: test (428/428), typecheck, lint, prettier,
and the sanitization gate.
