Add support for template formats (.dotx, .potx, .xltx) across validation
and the helper scripts.
Consolidate the shared office helpers into a single module, replacing the
pack/unpack pipeline with explicit zip/unzip steps. Extraction now rejects
symlink and path-traversal archive entries. Move run merging to a
standalone docx script, since it only ever applied to Word documents.
Fix the redlining validator so it compares against the original even when
a document has no tracked changes, which is when an untracked edit would
otherwise go unreported.
Provision a LibreOffice user profile per invocation so conversions work in
sandboxed environments.
Trim the skill docs to the guidance that earns its place.
docx: Add commenting and track-changes support. Reorganize OOXML
tooling into a shared office/ module.

bundle html2pptx as a tgz. Reorganize OOXML tooling into a shared
office/ module.

office/ module for OOXML pack/unpack/validate.
