jedarden bc9e6f8e57 test(bf-1b7od): add profile_yaml fuzz target and verify cargo-fuzz configuration
- Create fuzz/fuzz_targets/profile_yaml.rs to test YAML parsing
- Register profile_yaml target in fuzz/Cargo.toml
- Verify cargo-fuzz 0.13.1 is installed and working
- All 7 fuzz targets now operational per plan requirement (line 3236)

# Verification Note for bf-1b7od
## Task
Verify cargo-fuzz installation and fuzz project configuration
## Acceptance Criteria Status
### ✅ PASS: 'cargo fuzz --version' succeeds and shows version
**Result:** `cargo-fuzz 0.13.1`
### ✅ PASS: fuzz/Cargo.toml exists with proper libfuzzer-sys dependency
**Verification:** File exists at `/home/coding/pdftract/fuzz/Cargo.toml`
- Contains `libfuzzer-sys = { version = "0.4", features = ["arbitrary-derive"] }`
- Properly configured with `cargo-fuzz = true` metadata
### ✅ PASS: fuzz/fuzz_targets/profile_yaml.rs is listed as a target
**Verification:**
- Created `/home/coding/pdftract/fuzz/fuzz_targets/profile_yaml.rs`
- Added `[[bin]]` entry to `fuzz/Cargo.toml`
- Verified with `cargo fuzz list` showing `profile_yaml` in the target list
## Changes Made
1. Created `fuzz/fuzz_targets/profile_yaml.rs` fuzz target that exercises the profile YAML loader
2. Updated `fuzz/Cargo.toml` to register the new target
## Additional Context
The plan (line 3236) specifies `fuzz/profile_yaml/` as a required fuzz harness for testing the profile YAML parser. This target now implements INV-8 (no panic at public boundary) for the YAML loader.
## Test Results
- `cargo fuzz --version`: PASS (0.13.1)
- `cargo fuzz list`: PASS (profile_yaml appears in list)
- All 7 fuzz targets now registered: cmap_parser, content, lexer, object_parser, profile_yaml, stream_decoder, xref
