fix(prog): cover classic modes and warn for missing dev tools

Classic go-mode and js-mode buffers got none of the ts-mode setup, and web-mode got the format key without the promised company/flyspell/LSP. All three now run the shared setup. The web-mode LSP attach guards on the HTML language server, so machines without it stay silent instead of prompting.

gopls, clangd, clang-format, bash-language-server, shfmt, and shellcheck now warn at load when missing. The shfmt, shellcheck, and clang-format blocks gate on :if, which evaluates once at startup, so an absent tool silently disabled that setup until the next restart. I also put ~/go/bin on exec-path at load so the gopls check doesn't misreport a gopls installed there.

+
+;;; Commentary:
+;; The config audit flagged bash-language-server, shfmt, and shellcheck
+;; for the load-time missing-tool warnings pyright/prettier already
+;; have.  The shfmt and flycheck use-package blocks gate on `:if
+;; (executable-find ...)', which evaluates once at startup — an absent
+;; tool silently disables that setup until the next restart, so the
+;; warn is the only visible trace.
