Subject: [PATCH] perf: replace grep -q here-string with ZSH built-in pattern
 matching

Replace `grep -q "literal" <<< "\$var"` with `[[ "\$var" == *pattern* ]]`
in macos-notvscode.zsh (4 occurrences) and aliases/go.zsh (1 occurrence).

ZSH built-in string matching requires no subshell or external process,
making these checks faster and more portable.

Affected functions:
- is-at-home (macos-notvscode.zsh): 2 occurrences
- is-displaylink-connected (macos-notvscode.zsh): 2 occurrences
- golangci-lint-with-retry (aliases/go.zsh): 1 occurrence
