IndexError in Info.__init__: spot market with out-of-range token index crashes SDK initialization

[massimilianopetra]

Description

Since SDK version 0.23, Info.__init__() crashes with IndexError: list index out of range
when the spotMeta API returns a spot market whose token index exceeds the length of the
tokens list.

Steps to reproduce

from hyperliquid.info import Info
info = Info('https://api.hyperliquid.xyz', skip_ws=True)

Traceback:
File ".../hyperliquid/info.py", line 48, in init
base_info = spot_meta["tokens"][base]
IndexError: list index out of range

Root cause

The spotMeta API currently returns a market named @367 in universe with
tokens: [479, 0], but the tokens list has only 464 entries (indices 0–463).
So spot_meta["tokens"][479] raises IndexError.

Verified with:

import requests
resp = requests.post('https://api.hyperliquid.xyz/info', json={'type': 'spotMeta'})
data = resp.json()
for u in data['universe']:
    base, quote = u['tokens']
    if base >= len(data['tokens']) or quote >= len(data['tokens']):
        print('OUT OF RANGE:', u['name'], 'base=', base, 'quote=', quote, 'tokens len=', len(data['tokens']))
# OUT OF RANGE: @367 base= 479 quote= 0 tokens len= 464

Suggested fix

Wrap the offending lines in a try/except IndexError: continue to skip incomplete
markets gracefully:

base, quote = spot_info["tokens"]
try:
    base_info = spot_meta["tokens"][base]
    quote_info = spot_meta["tokens"][quote]
    self.asset_to_sz_decimals[asset] = base_info["szDecimals"]
    name = f'{base_info["name"]}/{quote_info["name"]}'
    if name not in self.name_to_coin:
        self.name_to_coin[name] = spot_info["name"]
except IndexError:
    continue

Impact

This bug makes the SDK completely unusable — Info() crashes on import,
breaking all read and trading operations.

Environment

• hyperliquid-python-sdk version: 0.23
• Python: 3.10
