feat: optimized AIOX agents and skills for Grok Build (#800)

* feat: add optimized AIOX agents and skills for Grok Build

Introduce .grok/ integration with token-efficient agent profiles,
slash skills, roles, personas, and compact rules. Add regenerable
sync script (npm run sync:skills:grok) so Grok stays aligned with
.source agents under .aiox-core/development/agents/.

* fix: improve grok-skills-sync purpose metadata for IDS registry

Clarify the generator module purpose so entity-registry extraction no
longer picks an unrelated CodeRabbit comment string.

* test: harden flaky pre-push suites for local agent pollution

Make Claude subagent governance validate the core aiox-* set instead of
exact directory equality, and guard dev-context-loader cacheHits when
status/shape is incomplete.

* fix: regenerate install manifest for entity-registry hash

CI Install Manifest Validation failed because data/entity-registry.yaml
hash no longer matched install-manifest.yaml after IDS updates.

* fix: address CodeRabbit review on Grok skills sync

Escape YAML/TOML scalars, constrain generated write paths under .grok/,
block git push for squad-creator, label markdown fences, and keep the
cacheHits > 0 assertion in dev-context-loader.

* chore: sync entity-registry and install manifest after IDS hook

Keep install-manifest hash aligned with entity-registry so CI
Install Manifest Validation stays green.

+# Grok Skills/Agents Sync
+
+Gera artefatos otimizados do AIOX para o **Grok Build TUI**.
+
+## Usage
+
+```bash
+# From repo root
+npm run sync:skills:grok
+npm run sync:skills:grok:dry
+```
+
+## Outputs
+
+| Path | Content |
+|------|---------|
+| `.grok/agents/*.md` | Agent profiles nativos (frontmatter Grok) |
+| `.grok/skills/aiox-*/SKILL.md` | Skills de ativação de persona |
+| `.grok/skills/aiox-sdc/` etc. | Skills de workflow |
+| `.grok/roles/*.toml` | Defaults de capability para subagents |
+| `.grok/personas/*.toml` | Overlays comportamentais |
+| `.grok/rules/aiox-core.md` | Regras compactas always-on |
+| `.grok/README.md` | Documentação da integração |
+
+## Design
+
+- **Token-efficient:** prompts condensados; YAML completo fica em `.aiox-core/development/agents/`
+- **Authority-safe:** matriz de autoridades AIOX embutida (ex.: só devops faz push)
+- **Regenerável:** re-rode o sync após mudanças nos agents fonte
+
+## Source
+
+Lê agents via `ide-sync/agent-parser` a partir de `.aiox-core/development/agents/`.
+Overlays de perfil Grok: `AGENT_PROFILES` em `index.js`.
