docs(prompts): align install / runbook / test-writer with LISA loader and CI lint

[LiliDeng]

• install-lisa: capture LISA_HOME / PYTHON / VENV after install, write them to /memories/session/lisa-install.md, set env vars, and add troubleshooting for venv-related 'lisa not found' / wrong Python. Require verifying the running LISA's root via python -c 'import lisa, pathlib; print(pathlib.Path(lisa.file).parent.parent)' and recording that path (not pwd) as LISA_HOME.

• lisa_runbook_generator: add Step 0 to resolve LISA_HOME (session memory -> env var -> workspace probe -> ask user) before emitting YAML; require absolute extension: paths (Rule 8); reflect venv activation in the run command shown to the user; add troubleshooting for ModuleNotFoundError: No module named 'microsoft'. Document _fix_path_for_old_code_layout semantics so 'import_builtin_tests: true' is the primary pattern for microsoft tests.

• lisa_test_writer: add Step 9 Lint Gate documenting the CI stack (black, isort, flake8, mypy, pylint) inline so generated test cases satisfy pyproject.toml / pylintrc, and require running the five local commands before reporting completion.

Pull request overview

This PR updates the GitHub Copilot prompt docs used for LISA install/runbook/test-writing workflows, aiming to better align the guidance with LISA’s runbook loader behavior and the project’s CI linting expectations.

Changes:

• Add a mandatory “Lint Gate” step to the test-writer prompt to require local lint/type-check verification before completion.
• Add a “Locate the executing LISA install” step and clearer guidance around import_builtin_tests vs extension: for Microsoft testsuite loading in runbooks.
• Extend the install prompt with steps to capture and persist LISA_HOME/PYTHON/VENV in session memory and add troubleshooting for common venv / module import failures.
