feat: Add Promotion-Time Attestations for Stella Ops

- Introduced a new document for promotion-time attestations, detailing the purpose, predicate schema, producer workflow, verification flow, APIs, and security considerations.
- Implemented the `stella.ops/promotion@v1` predicate schema to capture promotion evidence including image digest, SBOM/VEX artifacts, and Rekor proof.
- Defined producer responsibilities and workflows for CLI orchestration, signer responsibilities, and Export Center integration.
- Added verification steps for auditors to validate promotion attestations offline.

feat: Create Symbol Manifest v1 Specification

- Developed a specification for Symbol Manifest v1 to provide a deterministic format for publishing debug symbols and source maps.
- Defined the manifest structure, including schema, entries, source maps, toolchain, and provenance.
- Outlined upload and verification processes, resolve APIs, runtime proxy, caching, and offline bundle generation.
- Included security considerations and related tasks for implementation.

chore: Add Ruby Analyzer with Git Sources

- Created a Gemfile and Gemfile.lock for Ruby analyzer with dependencies on git-gem, httparty, and path-gem.
- Implemented main application logic to utilize the defined gems and output their versions.
- Added expected JSON output for the Ruby analyzer to validate the integration of the new gems and their functionalities.
- Developed internal observation classes for Ruby packages, runtime edges, and capabilities, including serialization logic for observations.

test: Add tests for Ruby Analyzer

- Created test fixtures for Ruby analyzer, including Gemfile, Gemfile.lock, main application, and expected JSON output.
- Ensured that the tests validate the correct integration and functionality of the Ruby analyzer with the specified gems.

 - `SCANNER-CLI-0001`: Completed Spectre table wrapping fix for runtime/lockfile columns, expanded Ruby resolve JSON assertions, removed ad-hoc debug artifacts, and drafted CLI docs covering `stellaops-cli ruby inspect|resolve`. Pending: final verification + handoff once docs/tests merge.
 - `SCANNER-CLI-0001`: Wired `stellaops-cli ruby inspect|resolve` into `CommandFactory` so the verbs are available via `System.CommandLine` with the expected `--root`, `--image/--scan-id`, and `--format` options; `dotnet test ... --filter Ruby` passes.
 - `SCANNER-CLI-0001`: Added CLI unit tests (`CommandFactoryTests`, Ruby inspect JSON assertions) to guard the new verbs and runtime metadata output; `dotnet test src/Cli/__Tests/StellaOps.Cli.Tests/StellaOps.Cli.Tests.csproj --filter "CommandFactoryTests|Ruby"` now covers the CLI surface.
-- `SCANNER-ENG-0016`: 2025-11-10 — resumed to finish `RubyLockCollector` + vendor cache ingestion (Codex agent) per §4.1–4.3, targeting lockfile multi-source coverage and bundler group metadata.
+- `SCANNER-ENG-0016`: 2025-11-10 — Completed Ruby lock collector and vendor ingestion work: honour `.bundle/config` overrides, fold workspace lockfiles, emit bundler groups, add Ruby analyzer fixtures/goldens (including new git/path offline kit mirror), and `dotnet test ... --filter Ruby` passes.
+- `SCANNER-ENG-0009`: Emitted observation payload + `ruby-observation` component summarising packages, runtime edges, and capability flags for Policy/Surface exports; fixtures updated for determinism and Offline Kit now ships the observation JSON.
