chore: add agents/reports to gitignore and update agent infrastructure with timestamp streaming, write budget, and codename generation

- Add `agents/reports/` to `.gitignore` to prevent generated agent report files from being tracked
- Implement `_TimestampStream` class and `install_timestamps()` function in `agents/agent.py` for prefixing stdout/stderr with timestamps and elapsed time
- Export `install_timestamps`, `set_write_budget`, `clear_write_budget`, and `set_shell_restricted` from `agents/base.py`; add `_RUN_LOCK`, `AGENT_ICONS` dictionary, and `WRITE_BUDGET = 20` constant
- Add `report_codename()` function and `CODENAME_ADJECTIVES`/`CODENAME_ANIMALS` tuples to `agents/core/__init__.py` for generating random agent report codenames
- Expand `WRITE_TOOLS` tuple in `agents/core/__init__.py` to include `replace_lines`, `insert_lines`, and `delete_lines`; remove `SWARM_TOOLS` from `payloads_for` exclusion list
- Update `CLAUDE.md` and `AGENTS.md` documentation with dataset column initialization rules and new agent infrastructure details
- Reorder route table in `README.md` to list `/uploads` before `/messages` and document Swagger/ReDoc/OpenAPI schema endpoints
