Brian Madison 1f488c956a feat(skills): TOML-based agent customization with stdlib Python resolver
Re-applies PR #2282's three-layer customization model (skill defaults →
team → user) but swaps YAML for TOML and uv for stdlib tomllib. Users
no longer need uv, pip, or a virtualenv — plain python3 (3.11+) is
sufficient, since tomllib shipped in the standard library.

## Schema changes vs PR #2282

- Flat agent schema: fields live directly under [agent], no nested
  metadata/persona sub-tables. Easier to author, less indentation.
- Non-configurable identity: name and title are declared in
  customize.toml as source-of-truth metadata (for future skill-manifest
  generation) but SKILL.md ignores overrides there — identity is
  hardcoded to preserve brand recognition.
- role redefined: now describes what the skill does for the user
  within its module phase, not a restatement of the title.
- persistent_facts replaces the activation-time file-context load AND
  the old memories concept. Entries can be literal sentences or
  file: prefixed paths/globs; avoids collision with the upcoming
  runtime memory sidecar.
- activation_steps_prepend / activation_steps_append harmonized across
  agents and workflows (replaces agent-specific critical_actions).
- [workflow] namespace mirrors [agent] for workflow customization.
  Same four structural rules, same field vocabulary.

## Resolver (src/scripts/resolve_customization.py)

Four purely structural merge rules, zero field-name hardcoding:

  - Scalars: override wins
  - Tables: deep merge
  - Arrays of tables where every item has `code` or `id`: merge by
    that key (matching keys replace, new keys append)
  - Any other array: append

No removal mechanism — overrides cannot delete base items. Fork the
skill or override by code with a no-op value to suppress defaults.

## Agents ported (6)

All six BMad agents now ship customize.toml + rewritten SKILL.md:
analyst (Mary), tech-writer (Paige), pm (John), ux-designer (Sally),
architect (Winston), dev (Amelia). Each uses the same 8-step
activation template: resolve → execute prepend → adopt persona →
load persistent facts → load config → greet (with {agent.icon}) →
execute append → dispatch or present menu.

Step 8 supports fast-path invocation: "hey Mary, let's brainstorm"
dispatches the matching menu item directly after greeting, skipping
the menu render when intent is clear. Chat, clarifying questions,
and bmad-help remain available when nothing on the menu fits.

## Installer + tooling

- _bmad/scripts/ provisioned on install (copies src/scripts/)
- _bmad/custom/ seeded with .gitignore for *.user.toml on fresh install
- Non-module-dir filter extended to skip _memory, memory, docs,
  scripts, and custom when scanning for modules
- Dead _config/agents/ directory no longer created
- metadata.capabilities removed from agent-manifest.csv and schema
- eslint config extended to cover src/scripts/**
- validate-file-refs.js knows about custom/ as install-only

## Deferred for follow-up

- bmad-product-brief workflow port (the pilot that demonstrates
  [workflow] + on_complete)
- Translated docs (cs/fr/vi-vn/zh-cn) — regenerate from English
