Update to cmem-plugin-template v9.7.0

[seebi]

💪 What

• Updates .copier-answers.yml from template v9.5.0 to v9.7.0
• Replaces the &preparation YAML anchor in Taskfile.yaml with two internal tasks, prepare and package:exists, so a task declaring its own deps can no longer silently drop what the anchor added
• Restores poetry:install as a dependency of build, and removes it from both format tasks, so the PostToolUse formatting hook keeps working while pyproject.toml is ahead of the lock file
• Removes the template:feedback-check and check:prepare tasks; the Stop hook now runs python3 .claude/hooks/template-feedback.py directly instead of through task
• Adds a least-privilege permissions: block to check.yml, pins xportation/junit-coverage-report to v1.0.3 and marks both reporting steps continue-on-error
• Adds the deliberately empty [tool.pytest.ini_options] table to pyproject.toml
• Refreshes every dependency via poetry update — notably cmem-cmemc 25.6.2 → 26.2.1, cmem-cmempy 25.4.0 → 25.5.0, click 8.4.2 → 8.5.0, packaging 24.2 → 26.3
• Updates the shipped copier-update and plugin-implementation skills and .claude/rules/

🤔 Why

• This is the only way a generated project picks up template changes; there is no self-updating automation
• Two of the fixes matter here directly: without the pytest table, a pytest.ini, tox.ini or setup.cfg anywhere above this checkout could set the project's rootdir and inject its own addopts into this suite; and without the permissions: block, a pull request from a fork reds the whole check on a token it cannot be given
• The cmem-cmemc bump moves past the click 8.5 incompatibility (Unknown color '') that took several sibling repositories' pipelines red

👩‍🔬 How to validate

• task format:fix on a checkout whose lock file is behind pyproject.toml — it formats rather than failing on poetry install
• package_dir= task check — package:exists fails loudly instead of checking nothing
• task build on a fresh clone with no virtualenv — it creates one rather than failing in poetry run
