What

Adds the Week 1 deliverable: a one-page summary of the sources we found and the case study's salient points.

Closes #10

• docs/reports/week-1-summary.md: the summary, readable on GitHub.
• docs/reports/week-1-summary.tex and docs/reports/week-1-summary.pdf: the LaTeX source and the compiled one-page PDF for submission.
• docs/SATCHEL_PROJECT.md: ticks the last three "Primary sources to collect" boxes, now that media ([Research] Collect media coverage of the S3 migration (context only) #5), cloud pricing ([Research] Collect current AWS S3 and Azure Blob Storage pricing pages and calculators #6) and on-prem prices ([Research] Collect hardware, power, colocation and bandwidth price references for the on-prem estimate #7) are merged.

Why

Week 1's deliverable. It covers:

• Sources: 57 logged, 27 of them primary.
• Problem: why Dropbox left S3.
• Solution: Magic Pocket in brief.
• Outcome: with the S-1 caveat that "Infrastructure Optimization" isn't Magic Pocket alone.
• Cost inputs so far: for the exercise.
• Open questions for Week 2.

How to check it

Read the PDF and check it fits on one page. Every figure has a Source Log ID.

Checked the source totals and all summary figures against the merged research notes. The Markdown and LaTeX agree, the PDF is valid and renders as one readable A4 page with no clipping, every required issue #10 section is present, and CI is green.
