fix(deps): include e2b in full extra

[dannyward630]

Summary

This is a small follow-up for SWE-agent#792.

The upstream pylint workflow installs .[full] and then lints the whole minisweagent/ package. The E2B environment imports e2b lazily, but pylint still resolves those imports while checking the new module. Adding the e2b extra to full makes the workflow install the optional SDK before linting the E2B backend.

Validation

• .venv/bin/python -m pip install -e '.[e2b]'
• .venv/bin/pylint src/minisweagent/environments/extra/e2b.py --errors-only
• .venv/bin/python -m pytest tests/environments/extra/test_e2b.py
• .venv/bin/ruff check pyproject.toml src/minisweagent/environments/extra/e2b.py tests/environments/extra/test_e2b.py
• git diff --check

Closing this follow-up because it is now obsolete. Its patch is byte-equivalent to 21d7e63d, which is already present on SWE-agent#792, and the current upstream PR head includes mini-swe-agent[e2b] in the full extra.

I also verified the current SWE-agent#792 head:

• focused E2B and SWE-bench tests — 50 passed, 8 skipped
• Ruff on the affected modules/tests — passed
• git diff --check — passed
