Summary

Implements COR-1258: generate a CycloneDX (1.7, latest) SBOM immediately after a scan, alongside the SARIF report.

New corgea scan --sbom [FILE] flag (default bom.json): after the blast scan completes and any --out-format report is written, a CycloneDX SBOM is generated locally from the project tree via the offline deps engine — no server changes, no network.
CycloneDX emitter upgraded from bare 1.4 to spec 1.7: serialNumber (urn:uuid), metadata (timestamp, tool, root component), bom-ref on every component, dependsOn grouped per ref. Output validates against the official bom-1.7.schema.json; corgea deps sbom shares the same emitter.
Maven: ${property} / ${project.version} version placeholders now resolve before purl construction, and the scanner emits root→dependency edges (the dependencies array was always empty for pure-Maven projects).
Detected-but-unsupported ecosystems (Go, Cargo) now print a stderr warning instead of silently producing an empty-looking SBOM.
deps subcommands error cleanly (exit 2) on nonexistent paths instead of succeeding with empty output.

Compliance enrichment (licenses, scope, hashes, Go/Cargo coverage) is tracked separately in COR-1733.

Test plan

cargo test — 543 passed, 0 failed (clippy clean, fmt clean)
New e2e test tests/cli_scan_sbom.rs: full stubbed scan flow → default bom.json, custom filename, no file without the flag
Maven property/edge coverage in maven_tests.rs + new java-maven-props fixture
Ecosystem-warning + nonexistent-path CLI tests in cli_deps.rs
Generated SBOMs validated against the official CycloneDX 1.7 JSON schema (npm + Maven fixtures)
5-scenario agent test sweep: 48/50 checks passing before these fixes; the 2 failures are addressed here

Add `corgea scan --sbom [FILE]` (default bom.json): after a blast scan completes, generate a CycloneDX SBOM locally from the project tree via the offline deps engine, alongside any --out-format report. - Upgrade the CycloneDX emitter from bare 1.4 to spec 1.7: serialNumber, metadata (timestamp, tool, root component), bom-refs on components, dependsOn grouped per ref. Output validates against the official bom-1.7 JSON schema. - Maven: resolve ${property} / ${project.version} version placeholders and emit root->dependency graph edges (dependencies array was always empty for pure-Maven projects). - Warn on stderr when detected ecosystems (Go, Cargo) are not included in the SBOM, instead of silently emitting an empty-looking document. - Error cleanly (exit 2) on nonexistent paths in deps subcommands. - Tests: e2e scan --sbom against the HTTP stub, Maven property/edge coverage, warning + path-error CLI tests, emitter unit tests. Scrub GIT_* env in the repo-info test so it passes inside git hooks.

…inherited-version deps - Omit component version/purl when the version is unresolved (? placeholder or ${...} Maven property) instead of emitting null versions and invalid @? purls; bom-ref keeps the internal id. - Dedup components by bom-ref and dependsOn per ref (schema uniqueItems). - Maven: project.version falls back to the parent's version for child POMs and resolves through properties (${revision} CI versioning). - scan --sbom write failures exit 1 with a clean error instead of panicking. All emitter outputs re-validated against the official bom-1.7 schema.

unsupported_ecosystem_label re-encoded which ecosystems produce graph nodes; derive it from ecosystems::is_graphed, defined beside the scanner dispatch so a future Go/Cargo scanner updates both in one place.

- dependencyManagement entries no longer emit components/edges; their versions fill versionless direct declarations in the same POM. - Property values resolve to a fixed point (bounded, cycle-safe) so chained ${...} references fully substitute. - Empty versions count as unresolved in the SBOM emitter (no bare @ purls). Parent/imported BOM resolution stays deferred to COR-1733.

…lution - to_cyclonedx filters the synthetic root by id, not display name, so a real package named 'root' keeps its component (no dangling dependsOn). - pom_project_version stops at the first nested section (dependencyManagement/build/reporting/profiles) so plugin versions can't hijack ${project.version}; parent fallback unchanged. - Property fixed-point resolution re-runs after project.version is inserted so properties aliasing ${project.version} resolve.

split_dependency_management and pom_project_version's parent handling used the same find-open/find-close/remove-section scanning; extract it into split_section. Compare the synthetic root via PackageId::root() instead of a raw string literal, matching the rest of the codebase.
