Dead functions `show_active_diagnostics_on_cursor_line` and `enable_inlay_hints` defined but never called in nvim-lspconfig.lua

[ooloth]

Current state

lua/config/plugins/specs/nvim-lspconfig.lua defines two functions — show_active_diagnostics_on_cursor_line (lines ~97–105) and enable_inlay_hints (lines ~107–110) — whose only call sites are commented-out lines at ~136–137 (-- show_active_diagnostics_on_cursor_line() and -- enable_inlay_hints(event) with speculative notes "let's see if I miss this" and "toggle on with leader-ui"). No uncommented code calls either function. A reader encountering these definitions cannot tell whether they represent planned-but-deferred behaviour or abandoned experiments.

Ideal state

• Both functions are deleted from the file, or
• Their call sites are uncommented and the functions execute at the intended edge (the LspAttach autocmd callback); the speculative notes are removed.
• No function definition exists in the file whose only call site is a comment.

Out of scope

• Deciding whether inlay hints or cursor-line diagnostics are desirable features — that is a separate question from removing dead code

Starting points

• lua/config/plugins/specs/nvim-lspconfig.lua lines ~97–137

QA plan

1. Open lua/config/plugins/specs/nvim-lspconfig.lua — expect neither show_active_diagnostics_on_cursor_line nor enable_inlay_hints appears as a function definition.
2. Run nvim --headless -c "qall" — expect a clean exit with no Lua errors.
3. Open a file with an attached LSP server — expect diagnostics and inlay hints to behave consistently (not broken by the removal).

Done when

Neither show_active_diagnostics_on_cursor_line nor enable_inlay_hints is defined in nvim-lspconfig.lua.
