test: reorganize flat test files into purpose-based subdirectories (phase 6)
Group 245 flat integration tests and 25 loose unit tests into
discoverable subdirectories per spec section 6:
integration/tools/{image,video,audio,document,data}/ (156 files)
integration/platform/ (64 files)
integration/generated/ (14 files)
integration/security/ (10 files)
unit/security/ (8 files, new subdir)
unit/api/ (7 files moved in)
unit/web/ (3 files moved in)
unit/shared/ (6 files moved in)
unit/image-engine/ (1 file moved in)
All moves via git mv (history preserved). Relative imports repaired
for both depth levels (platform/generated/security = +1, tools/ = +2):
static from-imports, dynamic import() calls, vi.mock() paths,
import.meta.dirname joins, and __dirname joins.
Vitest discovery unchanged (no test.include in config, recursive glob
matches subdirs, shard-by-hash unaffected). test-server.ts and
tool-route-drift.test.ts stay at integration root. fixtures/ untouched.
Parity gate: 13189 passing test names before = 13189 after (0 dropped).
