deps(bf-3mull): add serde_yaml dependency to fuzz/Cargo.toml

Adds serde_yaml = { version = "0.9" } to fuzz/Cargo.toml to support the profile_yaml fuzz target. Version matches pdftract-core's serde_yaml dependency (0.9).

Closes bf-3mull

+# Unmapped Glyph Test Module Isolation Results
+
+**Task:** Run each unmapped glyph assertion test module individually to isolate failures/hangs.
+
+**Run Date:** 2026-07-06
+
+## Summary
+
+All 4 test modules completed without hanging. No test modules froze or timed out.
+
+## Module Results
+
+### Module 1: unmapped_glyph_names_config
+**Status:** ✅ PASS
+**Tests:** 4/4 passed
+**Duration:** ~0.00s
+**Tests:**
+- `test_unmapped_glyph_names_defaults_to_empty` - PASS
+- `test_unmapped_glyph_names_specified` - PASS
+- `test_unmapped_glyph_names_empty_array` - PASS
+- `test_unmapped_glyph_names_minimal_config` - PASS
+
+### Module 2: encoding_recovery
+**Status:** ❌ FAIL
+**Tests:** 1/6 passed, 5/6 failed
+**Duration:** ~0.00s
+**Tests:**
+- `test_all_encoding_fixtures_exist` - PASS
+- `test_agl_only_fixture` - FAIL: "No /Root reference in trailer"
+- `test_fingerprint_match_fixture` - FAIL: "No /Root reference in trailer"
+- `test_corpus_recovery_rate` - FAIL: "Page index 0 out of bounds (document has 0 pages)"
+- `test_shape_match_fixture` - FAIL: "No /Root reference in trailer"
+- `test_no_mapping_fixture` - FAIL: "Page index 0 out of bounds (document has 0 pages)"
+
+**Issue:** Test fixtures appear to be corrupted or improperly generated (missing /Root reference, 0 pages).
+
+### Module 3: cjk_encoding
+**Status:** ❌ FAIL
+**Tests:** 0/5 passed, 5/5 failed
+**Duration:** ~0.00s
+**Tests:**
+- `test_all_cjk_fixtures_exist` - FAIL: Fixture file does not exist (`../../../tests/fixtures/cjk/cjk-chinese-gb18030.pdf`)
+- `test_cjk_big5_traditional_chinese` - FAIL: "Failed to open PDF: Failed to open PDF file"
+- `test_cjk_euckr_korean` - FAIL: "Failed to open PDF: Failed to open PDF file"
+- `test_cjk_gb18030_chinese` - FAIL: "Failed to open PDF: Failed to open PDF file"
+- `test_cjk_shiftjis_japanese` - FAIL: "Failed to open PDF: Failed to open PDF file"
+
+**Issue:** CJK fixture files are missing from the test fixtures directory.
+
+### Module 4: cmap_unmapped_glyphs
+**Status:** ✅ PASS
+**Tests:** 7/7 passed
+**Duration:** ~0.00s
+**Tests:**
+- `test_cmap_multiple_mappings_with_unmapped_check` - PASS
+- `test_cmap_range_mapping_with_unmapped_awareness` - PASS
+- `test_differences_overlay_consecutive_with_unmapped_filtering` - PASS
+- `test_differences_overlay_filters_all_g_series_unmapped` - PASS
+- `test_cmap_unmapped_glyph_skip` - PASS
+- `test_differences_overlay_filters_null_glyph` - PASS
+- `test_differences_overlay_filters_unmapped_glyphs` - PASS
+
+## Conclusion
+
+**No test hangs detected.** All 4 modules completed quickly (all under 1 second). The failures in `encoding_recovery` and `cjk_encoding` are due to missing or corrupted test fixtures, not test logic hangs.
+
+## Next Steps
+
+The parent bead `bf-60vlq` should focus on:
+1. Fixing the test fixtures for `encoding_recovery` (regenerate fixtures with proper /Root trailers)
+2. Ensuring CJK fixture files exist in `tests/fixtures/cjk/` directory
+3. The actual test logic (unmapped glyph assertions) is working correctly in modules 1 and 4
