feat: add dependency-aware bundle ordering

[vycdev2]

Summary

• derive cross-file bundle dependencies from resolver-owned definition/reference data, including E0205 forward-reference labels
• topologically order whole files with deterministic lexical tie-breaking while preserving declarations inside each file
• return structured ordering diagnostics for cycles and namespace-boundary leaks, preserve existing outputs on failure, and keep source-to-output manifests aligned with the selected order
• archive the implemented bundle-ordering contract under docs/completed/, add it to the completed-record inventory, and update all backlinks
• preserve the FFI, math-helper, random, encoding, and UUID documentation/code changes added to main since this branch was opened

Verification

• cargo test -q -p jett_driver bundle_project_ — passed: 11 bundle tests
• cargo fmt --check — passed
• cargo build — passed
• cargo test -q — passed: full Rust workspace suite
• git diff --check — passed

Risk

• Medium: this changes bundle file ordering and failure classification, but retains validation-before-write, limits reordering to whole files, and adds focused dependency-order, cycle, namespace-boundary, parse-priority, manifest, output-preservation, and agent-output coverage.

The implementation and test coverage look coherent, but the documentation status conflicts with this repository's taxonomy. This PR changes docs/open_design/bundle_ordering_contract.md to Status: implemented and calls it a completed contract, while AGENTS.md reserves docs/open_design/ for unresolved design and docs/completed/ for historical handoff material. Please move this record to docs/completed/, add it to the Completed Records inventory in docs/README.md, and update the references in docs/design.md (and any other backlinks) before merging.

In addition to the requested documentation-taxonomy change in my review, this branch now conflicts with the updated main after the approved PR batch was merged. Please rebase when moving the bundle-ordering record to docs/completed/ and preserve the intervening documentation/code changes.

[vycdev2]

Rebased this branch onto current main and addressed the requested documentation taxonomy updates:

• moved the implemented contract to docs/completed/bundle_ordering_contract.md;
• added it to the Completed Records inventory;
• updated the design and architecture backlinks while preserving intervening main changes.

During re-verification I also found and fixed a file-boundary case where concatenation could leak a preceding namespace into later root declarations. The bundler now rejects that unrepresentable order with a structured diagnostic and preserves existing output; two regression tests cover rejected and safe boundary orders.

cargo fmt --check, cargo build, cargo test -q, and git diff --check all pass.
