Update for PSI 0.34 compat, Literate cleanup and add precommit

[kdayday]

This pull request introduces several improvements to the documentation build pipeline, tutorial generation scripts, and test utilities. The main changes focus on making tutorial download links and image notes context-aware (working correctly for previews, dev, tags, and stable deployments), improving DataFrame rendering in documentation, and updating test logic for compatibility with changes in how simulation data is stored (PSI 0.34).

Testing and Simulation Updates:

• Test utilities have been updated for compatibility with PSI 0.34+: simulation results are now detected via the presence of a data_store directory rather than JSON files, and system population is requested explicitly when fetching decision problem results. [1] [2] [3]
• Obsolete helper functions for finding system files in test data have been removed.

Documentation and Tutorial Generation Improvements:

• Apply cleanup from Add literate.jl docs infrastructure PowerFlows.jl#356
• The tutorial build pipeline (docs/make_tutorials.jl) now computes the documentation base URL dynamically based on the deployment context, ensuring that download/view links work correctly for preview, dev, tagged, and stable builds. Download links can be absolute or relative depending on the environment or override variables. [1] [2]
• Image "view online" notes in generated notebooks are now appended only once per cell and detect multiple image formats, improving the user experience for Jupyter notebook viewers.
• DataFrame rendering in tutorials is now bounded by environment variables, preventing large outputs from overwhelming documentation pages. The output size can be configured with SIENNA_DOCS_DF_MAX_ROWS and SIENNA_DOCS_DF_MAX_COLS.
• The tutorial generation process is more robust: it cleans up both .md and .ipynb artifacts, and the pipeline is better documented and organized. (docs/make_tutorials.jlL56-R141, F59bbd0eL406R463)

CI and Formatting Enhancements:

• The documentation preview cleanup workflow now only runs for non-forked pull requests, preventing permission issues.
• The docs CI workflow sets the DOCUMENTER_CURRENT_VERSION environment variable appropriately for previews, tags, and branches, ensuring correct URL generation in all contexts.
• A pre-commit hook for Julia code formatting has been added, improving code quality and consistency.

Other Minor Changes:

• The hardcoded _DOCS_BASE_URL in docs/make.jl has been removed in favor of dynamic computation.
• The serialize keyword argument was removed from a build! call in a tutorial scenario script, reflecting upstream API changes.
