fix(#2545): use word boundary in Copilot/Antigravity path replacement to catch ~/.claude without trailing slash

The post-install scan used \.claude\b but the replacement functions used
\/\.claude\/ (requiring a trailing slash). Patterns like "configDir = ~/.claude"
(newline follows) and "~/.claude," (comma follows) passed the scan but were
never replaced. Switching to \b ensures all occurrences are replaced.
Also fixes the same gap in convertClaudeToAntigravityContent.

+ * "configDir = ~/.claude" (newline follows) or "~/.claude," (comma follows)
