Fix matchesWildcard to safely handle regex metacharacters in feature filter

[Copilot]

matchesWildcard in RepositoryTreeContentProvider only escaped . before calling String.matches(), leaving metacharacters like [, (, \, ?, + unescaped and causing PatternSyntaxException that would break the repository tree UI filter.

Changes

• Safe pattern construction: Split wildcard pattern on *, apply Pattern.quote() to each literal segment, rejoin with .* — fully isolating user input from regex interpretation
• Compiled Pattern with CASE_INSENSITIVE flag: Replaces ad-hoc .toLowerCase() calls with a proper case-insensitive Pattern.compile(..., Pattern.CASE_INSENSITIVE).matcher(str).matches()
• Added java.util.regex.Pattern import

// Before — throws PatternSyntaxException for input like "[eclipse"
String regex = wildcardPattern.replace(".", "\\.").replace("*", ".*");
return str.toLowerCase().matches(regex.toLowerCase());

// After — all metacharacters safely quoted
String[] segments = wildcardPattern.split("\\*", -1);
StringBuilder regex = new StringBuilder();
for (int i = 0; i < segments.length; i++) {
    if (i > 0) regex.append(".*");
    regex.append(Pattern.quote(segments[i]));
}
return Pattern.compile(regex.toString(), Pattern.CASE_INSENSITIVE)
    .matcher(str).matches();

Just as a heads up, I was blocked by some firewall rules while working on your feedback. Expand below for details.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Maybe we should reuse theaQute.libg.glob.Glob class which is used in lots of other places for wildcard filtering: e.g.

aQute.bnd.osgi.repository.BridgeRepository.list(String)
