Replace the hardcoded 4-server list in doctor LSP check with getAllServers()
from server-resolution.ts, which covers all 40+ builtin servers plus user
config. Output now shows server count with supported extensions, and verbose
mode expands to per-server detail lines.
Status: LSP 3 servers (.go, .py, .pyi, .ts, .tsx)
Verbose: LSP 3 servers (.go, .py, .pyi, .ts, .tsx)
typescript (.ts, .tsx, .js, .jsx)
pyright (.py, .pyi)
gopls (.go)
