sdivi-rust v0.2.16 — TS/JS/Python/Go/Java edges actually count

This release lands the three-milestone fix for cross-file edge detection in
non-Rust languages. Before v0.2.14, adapters for Python, TypeScript,
JavaScript, Go, and Java pushed whole import-statement text into
FeatureRecord::imports, which dependency_graph::resolve_import silently
dropped. modularity, community_count, and boundary_violation_rate
were therefore computed against a graph with almost no edges and reported
near-zero divergence regardless of what the code did.

After this release, the import graph reflects the actual import graph for
all six supported languages.

snapshot_version stays at "1.0". No CLI flag, exit code, or
.sdivi/config.toml key changed.

Highlights

• M25 — Adapter extract_imports rewrite. Python, TypeScript,
  JavaScript, Go, and Java adapters now emit bare module specifiers
  (e.g. "./utils", "foo.bar", "github.com/acme/lib") rather than
  whole-statement text. truncate_to_256_bytes and string_content
  consolidated into sdivi-parsing::text (eliminates five-way
  duplication previously flagged in the drift log).
• M26 — Resolver parent navigation + per-language module conventions.
  dependency_graph::resolve_import now walks parent directories for
  ../ and super:: instead of stripping prefix characters; gained
  per-language dispatch:
  • Python bare dotted specifiers (foo.bar) resolve as path lookups.
  • Go module-path imports resolve via the go.mod module prefix
    (auto-detected by the pipeline).
  • Java dotted imports resolve via standard Maven source roots plus
    auto-discovered module roots; wildcards (com.acme.lib.*) emit one
    edge per class file.
  • New API: build_dependency_graph_with_go_module(records, go_module)
    so WASM / non-pipeline callers can supply the Go module prefix
    without filesystem access.
• M27 — tsconfig path alias support. TypeScript and JavaScript
  adapters resolve compilerOptions.paths aliases declared in
  tsconfig.json / jsconfig.json. Aliases that point to non-existent
  targets are dropped without warning; standard relative and bare imports
  are unaffected.
• Non-blocking-note sweep. Six open items in
  .tekhton/NON_BLOCKING_LOG.md resolved or dispositioned: dynamic-import
  docstring softened in crates/sdivi-lang-javascript/src/extract.rs:32
  to match the test's grammar-version-dependent intent; remaining notes
  closed with carry-forward justifications.

Impact on existing baselines

The first snapshot taken on a Python, TypeScript, JavaScript, Go, or Java
project after upgrading from ≤ v0.2.13 will show a large coupling_delta
and community_count_delta against the prior baseline. This is a
correctness fix, not a schema change.

Recommended actions:

• Re-baseline at the M25+M26 boundary, or
• Apply a one-time per-category threshold override with expires set
  1–2 weeks out to absorb the cutover. See MIGRATION_NOTES.md for the
  exact override block.

Rust-only projects are unaffected; Rust import resolution did not change.

What did not change

• snapshot_version is still "1.0". v0.2.13 snapshots load and diff
  cleanly under v0.2.16.
• Public API additions only: build_dependency_graph_with_go_module is
  additive; the existing build_dependency_graph(records) continues to
  work and dispatches with go_module = None.
• WASM TypeScript types remain tsify-derived from the same Rust types.
  Existing JS/TS callers using WasmAssembleSnapshotInput need no
  changes.
• Snapshot atomic-write, retention, and exit-code contracts unchanged.
