fix: restore agent files accidentally modified in Docusaurus merge (#1191)

* fix: restore agent files accidentally modified in Docusaurus merge

Restores 25 agent files to their pre-merge state:
- Trigger format with shortcuts (WS, CH, BP, etc.) restored
- Fuzzy matching syntax restored
- BMB module: restores separate agent-builder, module-builder,
  workflow-builder agents; removes consolidated bmad-builder

Also updates test to match restored trigger format.

Note: Schema validation needs update in follow-up commit.

* fix: normalize trigger fuzzy match format for schema validation

- Add dashes to fuzzy match text to match kebab-case triggers
- Add missing 'chat' kebab in CH triggers (CH or chat or fuzzy match on chat)
- Relax schema to allow 1-3 char shortcuts and skip shortcut derivation check
- Remove compound-wrong-shortcut test fixture (no longer validated)

All 24 agent files now pass schema validation.
