feat(hooks): seed fresh-clone tier wiring across all 3 layers (FPLAN-0284 P5)

Closes the deployment gap — cadence_config.json + the settings.json bridge are machine-local (gitignored), so fresh clones needed the tiered wiring seeded from committed sources:
- cadence.py DEFAULTS (keystone): adds tier0(period 1) + navmap(period 5) to the code fallback, so a fresh clone with no cadence_config.json gets tiered cadence automatically (was defaulting tier0 to period 5).
- setup.sh: fresh-install bridge seed now emits tier0_kernel + navmap, drops global_prompt.
- provider_manifest.json: doctor update path adds the tiered entries on existing machines, drops global_prompt.

Convergence: the committed hooks.json (global_prompt enabled:false) means even a stale settings.json with a global bridge is skipped by the engine. 615/615 tests (1 new: test_defaults_include_tiered_loaders), seedgo 100%.
