fix: sync multiplayer exploration via vote system and fix combat bugs

- Add room vote system for multiplayer exploration (prevents players from independently moving the party to different rooms) - Fix Healer skill targeting: use ally cursor (Shift+Tab) instead of monster cursor, preventing wrong-target or out-of-bounds access - Prevent duplicate action submissions in the same combat turn - Drain stale actions from channel between turns - Block dead players from submitting actions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

+## Deployment (tolelom.xyz)
+
+The game runs as a Docker container on the Mac Mini server, behind Caddy reverse proxy.
+
+**Server structure:**
+```
+~/server/
+├── docker-compose.yml      # All services (caddy, gitea, catacombs, etc.)
+├── caddy/Caddyfile          # Reverse proxy config
+└── apps/catacombs/          # Git clone of this repo
+```
+
+**First-time setup:**
+```bash
+cd ~/server
+git clone https://git.tolelom.xyz/tolelom/Catacombs.git apps/catacombs
+```
+
+Add to `docker-compose.yml` services:
+```yaml
+  catacombs:
+    build: ./apps/catacombs
+    restart: always
+    logging: *default-logging

+        limits:
+          memory: 64m
+          pids: 200
+```
+
+Add `catacombs_data:` to the `volumes:` section.
+
+Add to `caddy/Caddyfile`:
+```
+catacombs.tolelom.xyz {
+    encode gzip zstd
+    reverse_proxy catacombs:8080
+}
+```
+
+**Deploy / Update:**
+```bash
+cd ~/server/apps/catacombs && git pull

Now web users enter nickname + password: - New accounts: set password (min 4 chars, bcrypt hashed) - Existing accounts: verify password to log in - On success: deterministic fingerprint SHA256(web:nickname) assigned - SSH users with real key fingerprints skip password entirely New files: store/passwords.go, store/passwords_test.go Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-26 07:16:20 +09:00

tolelom	206ac522c5	fix: Q returns to lobby instead of killing SSH session Pressing Q in game now cleans up the session and returns to lobby, instead of calling tea.Quit which terminates the SSH connection and shows "Connection lost" on web. Only Ctrl+C force-quits now. Also cleans up room on exit so abandoned rooms don't persist in lobby. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-25 23:18:36 +09:00
tolelom	24d9982b15	feat: increase turn timeout to 10s and expand help screen - Turn timeout 5s → 10s for more comfortable gameplay - Help screen now covers: lobby, exploration, combat, shop, classes, multiplayer tips, and general tips including skill tree controls Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-25 23:15:12 +09:00
tolelom	f6419b7984	fix: sort rooms by physical position so map numbers match layout Rooms were shuffled randomly before assignment, causing room 1 and 2 to be physically far apart on the map despite being logically connected. Now rooms are sorted top-to-bottom, left-to-right after BSP placement, so adjacent room numbers are also physically adjacent on the map.

tolelom	1efb78149c	fix: corridor visibility flood-fill so connected rooms appear linked Long L-shaped corridors had invisible middle sections because corridorVisible only checked 8 adjacent tiles for room proximity. Replace with flood-fill from room edges along corridor tiles so the entire path between connected rooms is visible.

tolelom	08d97b3f89	fix: use binary WebSocket frames for SSH PTY output SSH PTY output contains non-UTF-8 bytes (terminal escape sequences). Sending as TextMessage caused WebSocket decode errors. Switch to BinaryMessage and handle arraybuffer on the client side. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-25 22:30:24 +09:00
tolelom	1563091de1	fix: 13 bugs found via systematic code review and testing Multiplayer: - Add WaitingScreen between class select and game start; previously selecting a class immediately started the game and locked the room, preventing other players from joining - Add periodic lobby room list refresh (2s interval) - Add LeaveRoom method for backing out of waiting room Combat & mechanics: - Mark invalid attack targets with TargetIdx=-1 to suppress misleading "0 dmg" combat log entries - Make Freeze effect actually skip frozen player's action (was purely cosmetic before - expired during tick before action processing) - Implement Life Siphon relic heal-on-damage effect (was defined but never applied in combat) - Fix combo matching to track used actions and prevent reuse Game modes: - Wire up weekly mutations to GameSession via ApplyWeeklyMutation() - Implement 3 mutation runtime effects: no_shop, glass_cannon, elite_flood - Pass HardMode toggle from lobby UI through Context to GameSession - Apply HardMode difficulty multipliers (1.5x monsters, 2x shop, 0.5x heal) Polish: - Set starting room (index 0) to always be Empty (safe start) - Distinguish shop purchase errors: "Not enough gold" vs "Inventory full" - Record random events in codex for discovery tracking Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-03-25 20:45:56 +09:00
