 * Regression tests for issue #983 — Trae and Windsurf converters leak
 * unreplaced bare `~/.claude` / `$HOME/.claude` references.
 *
 * Both converters rewrote only trailing-slash `.claude/` forms, so bare
 * home-path references (configDir = ~/.claude, $HOME/.claude) survived
 * conversion and pointed users at the wrong config dir.
 *
 * Fix: add bare word-boundary replacements mirroring Cline (#782) and
 * Codex (#570) precedent, with a negative lookahead to preserve `.claude-plugin`.

// ─── _applyRuntimeRewrites install-path tests (windsurf) ────────────────────
//
// These tests exercise the ACTUAL install path that causes the user-facing leak.
// The converter functions are called at stage time to produce a Windsurf-branded
// copy, but _applyRuntimeRewrites is the path that runs at INSTALL time and
// rewrites any surviving ~/.claude / $HOME/.claude refs in the staged files.
//
// FAIL-BEFORE proof: prior to this PR, windsurf used /~\/\.claude\b/ which
// fires on "~/.claude-plugin" because \b matches between 'e' and '-'.  Running
// the test below against the old regex (`\b`) would:
//   - let bare $HOME/.claude survive (it used only /~\/\.claude\b/, missing $HOME form), AND
//   - corrupt "~/.claude-plugin" → "~/.windsurf-plugin".
// Both assertions in the test below would fail on the old code.
//
// PASS-AFTER: the fix changes to (?![\w-]) so:
//   - bare ~/.claude / $HOME/.claude (not followed by word-char or hyphen) → rewritten
//   - ~/.claude-plugin preserved (the '-' after 'e' is in [\w-])
//
// NOTE on pathPrefix choice: we use '~/.windsurf/' (a simple home-relative
// prefix) rather than '$HOME/.codeium/windsurf/' so that the corruption of
// '~/.claude-plugin' → '~/.windsurf-plugin' is directly detectable via
// result.includes('.windsurf-plugin').
