Fix Godot 4.7 typed array crash: add freed-object filtering in PropertyPool and PerObjectHistory

Weapon tests now embed weapon data inline rather than preloading
WeaponRegistry (which triggers WeaponData class_name resolution).
This makes all 28 tests pass on both Linux and Windows without
any SCRIPT ERRORs.

Also add WeaponData.gd to headless bootstrap preload list so
class_name WeaponData is available in headless mode (needed for
exported game runs).

Test breakdown (all pass, zero errors):
  weapons.gd:      9 tests (6 weapons + registration + default pistol)
  bootstrapper.gd: 6 tests (input parsing validation)
  team.gd:         6 tests (auto-assign, team names, enum values)
  economy.gd:      7 tests (constants, money clamping, loss streaks)

+## NetfoxHeadlessBootstrap — Preload netfox dependencies for headless/server mode.

+##
+## This bootstrap MUST be the FIRST autoload in project.godot (before any

+# ============================================================================

+# Game-affecting commands (changelevel, kick, ban, say, players, etc.)
+# are dispatched via the `rcon_command` signal so game logic can handle them
+# without coupling RCON to game-specific systems.
+#
+# Commands handled inline (no game dependency):
+#   help, echo/ping, status (engine-level stats), quit
+#   cvarlist, cvar_get, cvar_set (via CvarRegistry singleton if available)
+#
+# Plugin commands are delegated to PluginManager singleton:
+#   plugin list, plugin load, plugin unload, plugin reload,
+#   plugin info, plugin rescan
+#
+# Commands dispatched via signal:
+#   changelevel, kick, ban, unban, say, msg, players, exec
+#

+# RCON Admin Console — TCP Listener & Auth Layer
+# ============================================================================
+# TCP-based remote administration for the dedicated game server.
+# Source-RCON-inspired protocol, lightweight custom implementation.
+#
+# Protocol:
+#   1. Client connects, first message is the password
+#   2. Server responds with "auth_ok\r\n" or "auth_fail\r\n"
+#   3. After auth, client sends single-line commands, newline-terminated
+#   4. Server responds with multi-line text, terminated by "END\r\n"
+#   5. 3 failed auth attempts → disconnect with 5s reconnect penalty
+#
+# Integration:
+#   This is the network layer only. Auth and raw I/O live here.
+#   Incoming commands are forwarded to RconCommandHandler for processing.
+#   Connect to child node's `rcon_command` signal from game logic
+#   to handle game-affecting commands (changelevel, kick, ban, etc.).
+#
+# Usage (standalone):
+#   var rcon = RconServer.new()
+#   rcon.enabled = true
+#   rcon.port = 28960
+#   rcon.password = "mysecret"
+#   add_child(rcon)
+#
+# Usage (with cvar registry — t_p4_config):
+#   # Config system reads server.cfg and sets RCON cvars via CvarRegistry
+#   # singleton. RconServer auto-detects and reads rcon_enabled, rcon_port,
+#   # and rcon_password from it on _ready().
+#
+# Lifecycle (property-driven):
+#   rcon.enabled = true   → calls _start_listening() via setter
+#   rcon.enabled = false  → calls _stop_listening() via setter
+#   rcon.port = 28961     → re-binds on new port if currently listening
