fix(layering): parse static imports from OXC AST

[thymikee]

Summary

• Closes Architecture WS8: parse static imports on the existing OXC AST (fix the nine missed type-import pairs) #3293; umbrella Architecture quality: replace custom graph/layering code with maintained tools, close guardrail gaps, fix collocation (umbrella) #3276; stacked on refactor(graph): use shared engine for gate traversals #3316. Four files touched; no runtime dependency added.
• Static imports, re-exports and TSImportType share the existing OXC AST. Source-side qualifier symbols make named type dependencies visible to R75. Mixed type/dynamic edges stay distinct; malformed parses now fail closed.
• Nine recorded shapes retain isolated fixtures plus live production dependency assertions, including shutdown’s current operations-module declaration. Eight file pairs are newly resolved on the rebased tree. All 104 added occurrences are permitted type dependencies; there are no new layering findings. The test dependency into Apple internals uses its exported subpath.
• Removed the redundant ordering counter. Comment/template text produces no phantom edges. Evaluated value/dynamic edges and eager budgets remain unchanged; ownership includes type edges but its sets do not grow.

Validation

• Head 5f411172f460e2d16eabf97e94ca749f565ca554: pnpm check:affected --run passed every runnable check; pnpm check:fallow --base origin/main also passed. CI pending.
• Against parent 8ed2225f0: all 10,182 prior resolved edges retain identical symbols/kinds/lines/residue. No edges removed. Layering stdout, 22 cycle paths/kinds and all seven ownership sets (3,813 assignments) match exactly; R75 remains 13 shape / 22 authority files.
• Malformed-parse and template-text regressions fail before their fixes and pass afterward. The named import-type/R75 regression passes; the production-edge test also fails with TSImportType extraction disabled.

This PR is ready at 1c517f3, and the code looks good. All 14 checks pass on this head, including the jobs behind check:layering, package boundaries and mutation ownership. I did not run those checks myself, so the identical layering output and the unchanged ownership and R75 counts rest on that green CI and your description. I also did not confirm that the old regex scanner never made edges from import-like text inside template literals in production sources. No conflicts.

Not blocking: parseImports in scripts/layering/model.ts ignores parsed.errors, so a file OXC fails to parse would silently lose edges instead of failing the gate (typecheck makes this unreachable today), and the nine-pair test in scripts/layering/model.test.ts pins the live repository, so it breaks when one of those imports moves even if the parser is right. Take or leave both.

The cubic-dev-ai thread on the importTypeSourceName qualifier is fixed at this head, so you can resolve it: #3317 (comment)

This PR merges after its stacked base #3316 lands.

Addressed both broader review suggestions and rebased onto the corrected #3316 head. Final head: 65c5b4041f583d08278bf9acf33371ae8d18cf1f.

• parseImports now throws on OXC parse errors instead of returning an incomplete graph. The malformed-import regression failed with “Missing expected exception” before the fix and passes afterward.
• The nine recorded import-type shapes now use isolated source/export-map fixtures. They retain the real relative/workspace/typeof import forms and assert source-side symbols, without reading live declaration files. This matters on the new base: the contracts shutdown declaration moved upstream, so eight of the original nine pairs are newly missing from the regex scanner now.
• Removed the redundant ordering counter; the comparator preserves line, dynamic-before-static, and source-offset order with the language’s stable sort.
• Added a comments/template-text regression: the old scanner invented three edges from the fixture; the AST scanner returns none.

Explicit production comparison against parent 98b6e832c42edfa9a9a2c31efacf8bca0c3a1d82:

Measurement	Result
Previously resolved edges	All 10,182 retained byte-identically, including symbols, kinds, lines and residue
Added edges	104 type-only occurrences; eight new file pairs; zero value/dynamic additions
Removed edges	Zero — no production template-text phantom edges were lost
Layering stdout, including R75 counts	Byte-identical; 13 shape / 22 authority files
Cycle paths/kinds	All 22 identical
Mutation ownership sets	All seven identical, 3,813 assignments

Every new edge is a type dependency permitted by the existing rules; there are no new findings to suppress or repair. R6/R75 still inspect type edges under their existing semantics; eager closure/R4 use evaluated value edges, so their budgets do not grow. Ownership includes type edges but these do not add owners.

The eight new pairs are runner-provider → runner-artifact; interaction/index → gesture-runtime and touch-runtime; interaction/internal/interaction → contracts/android-observation; snapshot-runtime-binding → contracts/focus-runtime, interactor-types and type-text-runtime; sdk/artifacts → platform-android/mechanics. Other added occurrences are type references between file pairs already represented by existing imports.

The qualifier-symbol/R75 inline thread remains resolved. pnpm check:affected --run passed every runnable check on the exact pushed head. CI is running.
