[tests, docker, docs, scripts, ops] chore: remove internal-only assets and references

Drop internal build/CI assets and replace internal-infrastructure defaults
with neutral placeholders so a fresh clone is self-contained for external
users.

Packaging / infra:
- drop the internal pip index and --trusted-host from ops/requirements.txt
- remove the internal XPU docker assets and the P800 install tutorial
- ignore local AI-assistant rule directories

Examples / configs:
- default the Kimi NVFP4 blobfile install to the public PyPI index, with
  BLOBFILE_PIP_INDEX / BLOBFILE_PIP_TRUSTED_HOST as opt-in mirror overrides
- replace internal cluster paths and dataset locations in examples, configs
  and tests/embodied/config/prepare.sh with placeholders

LLM/VLM E2E suite:
- remove prepare_env.sh / download_datasets.sh, which bootstrapped models
  and datasets from internal object storage, plus their invocations in
  main_start.sh and pipeline_runner.sh
- drop the --ak / --sk credential passthrough and --skip_env
- remove per-model bos_path entries from the test configs
- remove the internal docker build assets and unreleased-chip baselines
