Initial commit: ia_dev pilot repo, agents and deploy scripts
**Motivations:**
- Provide a single repo for IA-driven piloting of all projects (agents, rules, deploy scripts).
- Reusable as git submodule; project-specific config in projects/ (no slug from submodule path).
**Evolutions:**
- Cursor agents: deploy-by-script, push-by-script, branch-align, fix, evol, fix-lint, fix-search, code, docupdate, gitea-issues-process, change-to-all-branches.
- Deploy scripts: pousse.sh (build_dirs from project config), bump-version.sh (version from project config), branch-align.sh, change-to-all-branches.sh.
- Project config schema in projects/README.md; lecoffreio.json as example.
**Pages affectées:**
- .cursor/agents/*.md, .cursor/rules/*.mdc, deploy/*.sh, projects/README.md, projects/lecoffreio.json, README.md, CLAUDE.md, config files.
