Phase 1 of the config refactor. Splits configuration into three clearly-owned
layers and removes per-install duplication:
- Global tier (~/.bmad/, $BMAD_HOME override): one-time identity + machine-wide
defaults. config.user.toml holds scope:user core answers (user_name, language)
so they're asked once per machine, not once per project.
- Per-module shipped-defaults floor (_bmad/{module}/module.toml): regenerated
every install; the resolver's lowest-priority layer.
- Project overrides (_bmad/config.toml): lean — only emits deltas from module
defaults. No more [agents.X] sections (agents live in module.toml floor).
Resolver chain (src/scripts/resolve_config.py) is now 7 tiers and supports
global-only operation (no _bmad/config.toml required). Customization cascade
(resolve_customization.py) splits cleanly from config: customize.toml files at
global, project, and custom tiers; never reads config.toml.
Installer (tools/installer/):
- New global-config.js: cross-platform resolver + dependency-free TOML reader.
- official-modules.js: silently reuses scope:user globals; logs a friendly note
showing what was reused/seeded and where to edit it.
- manifest-generator.js: writes per-module module.toml with placeholder
resolution for cross-key references (e.g. {output_folder}); routes core
scope:user answers to ~/.bmad/config.user.toml.
- Removed --ask flag.
Tests: 11 new Python resolver tests, 8 new customization-cascade tests,
suites 35/37/38/45/46 in test-installation-components.js updated/added for the
new contract (with BMAD_HOME isolation to avoid touching real ~/.bmad).
