fix: match ignore-paths against a symlink's own name

[Sanjays2402]

Closes #608

Description

make_exclusion_filter called path.resolve() before matching the ignore
patterns, which dereferences symlinks. As a result a symlink could only be
excluded by naming its target, never by the link name the user actually sees
in the tree. The filter now matches against both the path as given and its
resolved target (each made relative to the workdir where applicable).

#608 — "[BUG] ignore-paths/patterns do not work with symbolic link names"

Motivation and Context

Adding a symlink's name to ignore-paths or ignore-patterns silently did
nothing, so the linted file set included directories the user had explicitly
excluded. Matching the link name is what the configuration reads as, and the
target is still matched too, so existing configurations keep working.

How Has This Been Tested?

Added test_symlinked_ignore_path to tests/config/test_config.py. It creates
a directory, a symlink to it, and a profile with ignore-paths: [link], then
asserts the filter excludes the symlink and a file under it. The test fails on
the unpatched filter (AssertionError: assert False) and passes with the fix.
tests/config and tests/finder pass (30 passed); ruff check and
ruff format are unchanged from baseline on the touched files.
