v1.12.0 — ODP template ecosystem

Closes the last competitive-positioning gap with Anthropic's pptx skill.
Where pptx uses an HTML-design-loop, this release takes the other route:
curated templates the agent picks from, plus tools to inspect them per-slide
and extract new ones from any .odp/.otp/.pptx (PPTX via the v1.11
OOXML bridge).

Added

• inspect_template.py — JSON inventory of master pages, slide layouts,
  named styles, font declarations. The agent's per-slide layout-picking input.
• extract_template.py — distil any .odp/.otp/.pptx into a reusable
  template directory. Filters office:automatic-styles to keep only what
  master pages reference (and parent chains); copies master-page-referenced
  Pictures/; seeds LICENSE.txt/PROVENANCE.md/README.md.
• apply_template.py — one-call inject-styles + embed-pictures +
  validate-refs. Supports --template-name <shipped> and --template PATH.
• Three shipped templates in skills/odp/templates/:
  • dao-conference — deep-blue branded, logo bottom-right (migrated from
    examples/deck/styles.xml).
  • academic-blue — cream background, navy Lato + Source Serif.
  • minimalist-mono — near-white, JetBrains Mono + Inter.
• inspect_styles_xml and load_styles_xml helpers in odp_common.

Changed

• examples/deck/build_deck.py reduced from 90-line orchestration to a thin
  apply_template-based wrapper. The branded styles.xml and the logo
  moved into the shipped dao-conference template.

Installation

Templates live inside skills/odp/, so install_skills.py includes them
in every Smithery / skills.sh / Claude Code plugin install — no extra
download or configuration.
