fix: round 2 — completion speed, octal numbers, dead files

- Reduce asyncomplete popup delay 200ms→50ms for snappier completion
- Add nrformats-=octal: Ctrl-A on 007 now goes to 008, not 010
- Add formatoptions+=j: joining comment lines removes duplicate leaders
- Remove coc-settings.json (vestigial, CoC not used)
- Fix .gitignore: was blocking all *.json files unnecessarily
- Update README: Python LSP is pylsp only (pyright removed)
