fix(nvim): purge lingering telescope back-references

Four plugin specs still listed telescope (or telescope-dap) as a
dependency, causing :Lazy sync to silently re-install telescope
after Phase 3. Drop the explicit telescope dep from venv-selector
(v2 has its own picker UI) and from dap (telescope-dap was unused).
Delete cheatsheet.nvim and gitignore.nvim entirely — both are
pure-telescope frontends with no fallback, and removing telescope
broke them.
