feat: added mini game in every classic level

[Satvik-Singh192]

Description

This PR introduces a functional Tic-Tac-Toe mini-game triggered by an interactable pillar in the Level1 scene.
The design ensures the mini-game is played in a fully paused environment, with the AI logic running independently of the main game's time scale.

---

Methodology Overview

The integration relies on three distinct architectural components working together:

🧱 Physical Trigger and Prompt

• The PillarInteractor.cs uses a trigger collider (Is Trigger) to detect when the player (tagged "Player") is in range.
• It manages the display of the "Press E" prompt text.

⏸️ Flow Control (Pause/Resume)

• Upon pressing E, the interactor activates the game canvas and immediately sets Time.timeScale = 0f, fully pausing the main game loop, movement, and physics.
• The TicTacToeManager handles the close function, resetting Time.timeScale back to 1f when the player exits the mini-game.

🧠 Time-Independent AI Logic

• we handle AI turn execution inside the Update() function, driven by a simple boolean flag (isAwaitingAIMove).
• This ensures the AI moves instantly after the player's turn, bypassing the paused time scale and preventing the game from freezing.

Additonal Fixes:

I fixed a bug in Level 1 and level 3 where after any collison the velocity given to the player after knockback became residual and hindered the player movement. now there are no residual velocities on player if there is no input

@Just-Here-TO-Code please review my latest commit , i caught a bug where the game crashed cuz a script was accessing a absent property of a material on a collectible.
