Add Week 6: Grant Proposal Writing

22-slide deck (NIH-heavy with NSF mentioned, HBN/Pixar practicum anchor),
17 SVG icons, 3 source screenshots showing research-skills running on
Claude Code, Codex CLI, and Copilot in VS Code.

Companion blog page covers the 5-stage grant pipeline (NOFO, Aims,
Strategy, self-review, figure QA), the three rigor defences (NOFO
contract, cite-the-card, review boomerang), and the workflow for
/grant:grant-writing, /grant:grant-review, and /grant:grant-figure-qa.

Source-of-truth deck lives in the agent-presentation repo at
examples/week-06/. Adds Week 5 and Week 6 to the courses nav.
