Warden-Forged Heart mod

• Added the Warden-Forged Heart relic item (Combat tab). It is a pulsing sculk heart with a custom texture and tooltip.
• Right-click triggers Echo Blink: raycasts up to roughly 24 blocks, teleports you to the face of the targeted block (or the air block above it if needed), plays a warden-like thump, and leaves a trail of sculk soul particles.
• Sneak + right-click triggers Sonic Rupture: fires a 30-block sonic beam with sculk and sonic-boom particles, deals sonic boom damage to every mob along the line, applies strong knockback and brief darkness, and ends with a shockwave sound.
• Cooldowns: Blink ~1s (20 ticks), Sonic Rupture ~3s (60 ticks).

Implementation notes:

• Teleportation only completes when there is enough air at the hit face or the block above; otherwise nothing happens.
• The beam checks for entities within about a 1.2-block radius of the line from your eyes and pierces all of them without stopping on blocks.
• Item registration uses the common entrypoint and adds the relic to the Combat item group; language entries and model point at the new custom texture.

Known limitations / future ideas:

• No crafting recipe is provided; obtain the item via creative inventory or commands.
• Beam currently ignores block cover; add collision checks or visual screen distortion if you want a stricter line-of-sight feel.
