add SREBOT, SHARED, TSSBOT contents (fixup for #1223)

PR #1223 only staged the deletions of the old paths because the new
top-level directories were still untracked when the commit was authored.
This commit adds the actual restructured tree: SREBOT/ (existing bot),
SHARED/ (vromfs, data_parser, ICONS/MAPS/FONTS, DAGOR_FILES,
update_game_files), and TSSBOT/ (skeleton).

+# TSSBOT
+
+Sibling bot under `BOTS/`. Skeleton only — actual logic to be implemented.
+
+Shared game-data assets (vromfs, data parser, MAPS, ICONS, FONTS, DAGOR_FILES,
+`update_game_files.py`) live in `../SHARED/`. Add `../SHARED` to `sys.path`
+before importing `data_parser`:
+
+```python
+import sys
+from pathlib import Path
+sys.path.insert(0, str(Path(__file__).resolve().parents[2] / "SHARED"))
+from data_parser import UnitTags, LangTableReader  # etc.
+```
+
+## Layout
+- `BOT/`        — Python source for the bot (placeholder)
+- `web/`        — front-end / API server for TSSBOT (placeholder)
+- `start_bot.py` — entry point stub
