Subject: [PATCH 1/2] fix: pin tree-sitter below 0.26.0 to fix segfault in make
 test

tree-sitter 0.26.0 reimplemented Point as a native tuple subclass
(replacing the namedtuple), and that reimplementation has a memory
safety bug that corrupts the heap when Point objects are repeatedly
constructed/discarded, as chunking.py and query/__init__.py do. The
corruption doesn't crash immediately, so `make test` segfaulted at
different, seemingly unrelated tests across runs. Pinning to
>=0.25.1,<0.26.0 (still excluding the aarch64-linux-broken 0.25.0)
eliminates the crash.

Also widen the exception handling in chunking.py's parser lookup to
catch tree_sitter_language_pack's own Error hierarchy, not just
LookupError: the currently locked tree_sitter_language_pack (1.14.3)
raises DownloadError for an unrecognized language instead of the
LookupError it used to raise, and normalize the re-raised exception
back to LookupError so callers keep the same contract.
