fix(symfony-finder): make Glob::to_regex regex-crate compatible

Glob::toRegex emits PCRE-only constructs — the (?=[^\.]) look-ahead for
the strict-leading-dot rule, the possessive [^/]++ in /**/ segments,
and, via BaseExcludeFilter, the (?=$|/) dir-boundary look-ahead — which
the regex crate cannot compile, so `archive` and every
ArchivableFilesFinder path panicked. Rewrite the port to tokenize the
glob (mirroring the PHP loop's dispatch) and resolve every no-dot
constraint by recursive union expansion. The dir boundary must take
part in that expansion (a trailing `*` matching zero characters drops
the constraint onto the boundary itself), so BaseExcludeFilter now uses
the new Glob::to_regex_dir_boundary instead of string surgery.

Equivalence was verified against PHP 8.5.8 (vendored Glob.php +
preg_match) over 66,176 glob x flag x subject combinations with zero
divergence. Un-ignores the five archiver tests blocked on this and
updates GitExcludeFilterTest's expected pattern text, an explicitly
authorized exception to the no-test-modification rule.
