Add tablist API for player list data

[jkramer5103]

Summary

• add minescript.tablist() backed by the network entries used by Minecraft's player-list overlay, so server-created fake players are included
• expose each entry's profile and display names, UUID, latency, game mode, team, ordering, skin data, hat state, and optional list score
• expose the tab-list header, footer, and optional scoreboard objective
• preserve displayed text as both convenient plain text and structured Minecraft JSON
• support Python and Pyjinn, with generated API documentation and integration coverage

Usage

current_tablist = minescript.tablist()

players = current_tablist.players()
header_lines = (
    [] if current_tablist.header() is None
    else current_tablist.header().lines()
)
footer = (
    None if current_tablist.footer() is None
    else current_tablist.footer().plain
)

Live example

Tested on Donut SMP with Minecraft 26.2 and Fabric:

Tablist entries: 80
Header: '\nDonut SMP\n17.4K Players\n'
Footer: '\n$ 1.7B • 37 ms\n'
First entries: w00summer, N1ckifyy, 1sand, AhuvadeDih, BabyBeastpont, BurlyCloud_, Clxudyscute, Dkockysnoot_, Eljook, Enderscore24

This demonstrates that the API returns the server-created tab entries as well as the multiline header and footer status text.

Validation

• Fabric 26.2 build
• NeoForge 26.2 build
• Python and Pyjinn syntax compilation
• tab-list result transformation test with fake-player, multiline-header, and footer data
• in-game Fabric test against a real server tab list
• git diff --check

The Forge build could not resolve the repository's configured net.minecraftforge:forge:26.2-60.0.0:userdev dependency; the shared implementation compiled successfully through both Fabric and NeoForge.

Fixes #77.
