chore: untrack deliverables committed by mistake, and home the stray files

The previous commit used git add -A and swept in four binaries that were
deliberately untracked: the week-1 client report as .docx and .pdf, a duplicate
of it under output/documents, and imagem-teste.jpg, an input dropped in to test
with. None of them are the repository's to version. They are untracked here,
left on disk, and covered by .gitignore so the mistake cannot repeat.

Three files had no sensible home. The meeting notes sat at the repository root
under a 78-character name with spaces and accents, the roadmap generator lived
in tmp/ — a directory otherwise ignored as scratch — and its output in output/,
which is otherwise generated evidence. They are now docs/reuniao-2026-09-09-
anotacoes.pdf, tools/generate_dtf_report.py and docs/roadmap-cliente.pdf, with
CONTEXT.md and ROADMAP.md updated to match and a docs/README.md saying what each
document is for.

.gitignore no longer needs four rules to keep one generator out of an ignored
directory; tmp/ is scratch again.
