Martin Vogel d9adfeb688 fix(writer): open the graph DB wide-safe for non-ASCII cache paths
cbm_writer_open used a raw ANSI-CP fopen for the hand-rolled SQLite
writer - the one file-creating call on the dump chain without a
UTF-8-to-wide conversion. On a non-ASCII Windows profile
(C:\Users\Kovacs Janos) extract and resolve succeeded but the dump
failed with pipeline.err phase=dump: fopen could not create graph.db
under the profile-derived cache dir while cbm_mkdir_p (already wide)
had happily created the directory around it. Routed through cbm_fopen,
matching #700 (pass readers) and #973 (canonicalization); POSIX is
byte-transparent.

New Windows guard test_non_ascii_cache_dump.py indexes an ASCII repo
into a non-ASCII CBM_CACHE_DIR and requires a query_graph readback
with Function count > 0 - proving the DB was written to and reopened
from the non-ASCII cache, not merely that no error surfaced. The
existing non-ASCII guard only varied the repo path against an ASCII
cache, which is why this class went unseen.

The USERPROFILE-sourced env encoding question (Layer 2 - _environ is
ANSI-CP, not UTF-8) is deliberately not bundled; it needs verification
on a real Windows box and will be filed separately if the guard alone
does not settle it.

Closes #996
