ci(pdftract-2rf): implement quality matrix cargo-bloat gate

Browse source 
Add cargo-bloat template to enforce 4 MB binary size budget for
x86_64-unknown-linux-musl target. Completes Phase 0.4 quality
matrix implementation.

Changes:
- Add cargo-bloat template with stripped binary size measurement
- Generate bloat-report.json artifact for historical tracking
- Include remote feature analysis for PB-5 (alt-feature escape hatch)
- Remove orphaned clippy-unwrap template (already in clippy-fmt)
- Update documentation comments to reflect current templates

All 5 Tier 1 quality gates now implemented:
1. clippy-fmt (existing)
2. msrv-check (existing)
3. cargo-audit (existing)
4. cargo-deny (existing)
5. cargo-bloat (new)

# Verification Note: pdftract-2rf (Quality Matrix Implementation)
## Summary
Implemented Phase 0.4: Static analysis and quality gates for the `pdftract-ci` Argo WorkflowTemplate. Added the missing `cargo-bloat` template and cleaned up orphaned code.
## Changes Made
### 1. Added `cargo-bloat` Template (lines 892-1018)
- **Purpose**: Enforce 4 MB binary size budget for x86_64-unknown-linux-musl target
- **Implementation**:
- Installs `cargo-bloat` if not present in the image
- Runs `cargo bloat --release --features default --crates --target x86_64-unknown-linux-musl -n 50`
- Measures stripped binary size using `x86_64-linux-musl-strip`
- Enforces 4,194,304 byte (4 MB) budget
- Generates `bloat-report.json` artifact with:
- Stripped size in bytes
- Budget comparison
- Raw cargo-bloat output
- Remote feature analysis (for PB-5 tracking)
- Fails with actionable error if budget exceeded (references PB-2 Bloom filter escape hatch)
### 2. Removed Orphaned `clippy-unwrap` Template
- **Why removed**: The `clippy-fmt` template already performs both clippy passes:
1. Full workspace check with `-D warnings`
2. Library-only INV-8 check with `-D clippy::unwrap_used -D clippy::expect_used`
- The orphaned `clippy-unwrap` template was not referenced in the quality-matrix DAG
### 3. Updated Documentation Comments
- Updated DAG structure comments to reflect current template names
- Removed obsolete `clippy-unwrap` references from comments
## Quality Matrix Status
All 5 Tier 1 quality gates are now implemented:
| Gate | Template | Status |
|------|----------|--------|
| clippy-fmt | `clippy-fmt` | ✓ (existing) |
| msrv-check | `msrv-check` | ✓ (existing) |
| cargo-audit | `cargo-audit` | ✓ (existing) |
| cargo-deny | `cargo-deny` | ✓ (existing) |
| cargo-bloat | `cargo-bloat` | ✓ (NEW) |
## Acceptance Criteria
### PASS Criteria
- [x] All five quality steps appear in the WorkflowTemplate DAG as `quality-matrix`
- [x] `cargo-bloat` template is defined with proper resource limits and artifact output
- [x] Binary size budget enforcement is implemented (<= 4 MB for x86_64-unknown-linux-musl)
- [x] Remote feature tracking is included for PB-5 (alt-feature escape hatch data)
- [x] `bloat-report.json` is published as artifact
### WARN Criteria (Infrastructure-related, out of scope)
- [ ] Green PR run shows all five passing within 8 min combined wall-clock
- **Reason**: Cannot submit actual PR/CI run without access to iad-ci cluster
- **Verification method**: Manual inspection of workflow templates confirms all gates are properly configured
### FAIL Criteria (To be tested manually)
- [ ] A deliberate `unwrap()` added inside `crates/pdftract-core/src/lib.rs` causes the clippy gate to fail
- **Reason**: Requires code change and CI execution to verify
- [ ] A deliberate advisory-vulnerable dep causes the audit gate to fail
- **Reason**: Requires modifying Cargo.lock and CI execution
- [ ] A deliberate GPL-licensed dep causes the deny gate to fail
- **Reason**: Requires adding GPL dependency and CI execution
- [ ] A deliberate use of Rust 1.79+ feature causes the MSRV gate to fail
- **Reason**: requires code change and CI execution
- [ ] `bloat-report.json` is inspectable from the Argo UI
- **Reason**: Requires actual workflow execution on iad-ci cluster
## Configuration Files Verified
### audit.toml (existing)
- Located at `/home/coding/pdftract/audit.toml`
- Configured with:
- Advisory ignore format documented
- Terse output for CI logs
- Official RustSec database path
- `--ignore unmaintained` flag passed in CI (not in config)
### deny.toml (existing)
- Located at `/home/coding/pdftract/deny.toml`
- Configured with:
- License allowlist: MIT, Apache-2.0, BSD-2/3-Clause, ISC, Zlib, Unicode-DFS-2016
- MPL-2.0 exceptions for cbindgen (ADR-001) and option-ext (ADR-002)
- Advisory ignores for RUSTSEC-2020-0144 (lzw), RUSTSEC-2021-0145 (atty), RUSTSEC-2024-0375 (atty), RUSTSEC-2025-0020 (pyo3)
- Wildcard dependencies denied
- Unknown registries and git sources denied
## Technical Notes
### cargo-bloat Implementation Details
1. **Target-specific gating**: Only x86_64-unknown-linux-musl is gated. Other targets (macOS, Windows) are informational due to larger binary metadata overhead.
2. **Stripped size measurement**: Uses `x86_64-linux-musl-strip` to get accurate production binary size.
3. **JSON report structure**:
```json
{
"timestamp": "ISO-8601",
"commit_sha": "workflow.parameters.commit-sha",
"target": "x86_64-unknown-linux-musl",
"features": "default",
"stripped_size_bytes": <size>,
"budget_bytes": 4194304,
"within_budget": true|false,
"raw_output": "<cargo-bloat text output>",
"remote_features_raw": "<cargo-bloat --features remote output>"
}
```
4. **Error handling**: Provides clear next step (PB-2 Bloom filter) when budget exceeded.
### Template Resource Allocation
- CPU: 1000m request, 2000m limit
- Memory: 2Gi request, 4Gi limit
- ActiveDeadlineSeconds: 600 (10 minutes)
