fix(config): enable bittensor CLI arg parsing (BT_NO_PARSE_CLI_ARGS)

[Thykof]

Problem

On bittensor 10.4.x, the validator (and miner) crash at startup:

File "synth/utils/config.py", line 58, in check_config
    config.neuron.name,
AttributeError: 'NoneType' object has no attribute 'name'

Root cause

bittensor 10.4.x disables CLI argument parsing by default: bittensor.core.config.Config.__init__ early-returns when no_parse_cli() is true, and no_parse_cli() reads BT_NO_PARSE_CLI_ARGS which defaults to "true". So bt.Config(parser) skips parsing entirely and returns only DEFAULTS:

• config.neuron is None → check_config crash above
• config.netuid is dropped
• config.subtensor.network stays finney (ignores --subtensor.network test)

i.e. every --flag from entrypoint-validator.sh / entrypoint-miner.sh was silently ignored. This regressed when the repo moved to bittensor==10.4.1.

Fix

Set BT_NO_PARSE_CLI_ARGS=false inside config() before building bt.Config, so the neurons are configured from their CLI flags again. It's scoped to config() (not module import) so it never makes bittensor's logging machine parse pytest's argv during the test suite, and uses setdefault so an operator can still override.

One line covers both validator and miner (they share config()).

Verification

With the fix, Validator.config() built from a realistic argv resolves correctly and check_config() passes:

• netuid=247, subtensor.network=test, wallet.name, neuron.name/nprocs, retention.low.days, validator.mode, storage.backend
• check_config() no longer raises; neuron.full_path computes
• unit tests green; black/flake8 clean

Pull request overview

This PR fixes startup crashes/regressions introduced with bittensor==10.4.1 by ensuring Bittensor parses CLI arguments when building neuron configs (miner/validator), restoring expected behavior for --netuid, --subtensor.network, --neuron.*, etc.

Changes:

• Set BT_NO_PARSE_CLI_ARGS=false (via os.environ.setdefault) inside config() before constructing bt.Config(parser) to re-enable CLI arg parsing under Bittensor 10.4.x.
