fix(extensions): keep optional Deno imports optional

[kojiwakayama]

Summary

Deno 2.7.7 can report an unavailable optional first-party extension as:

Import "@veryfront/ext-auth-jwt" not a dependency

The classifier accepted only the older wording, not a dependency and not in import map, so build orchestration treated an absent optional builtin as a hard error for Deno scaffolds. The missing-extension regex now accepts both exact forms while still matching only the explicitly probed first-party specifier.

PR #3541 is the independent SSG fix needed for the ai-agent case in the combined 21-case template matrix. This PR is the optional-extension classifier fix and does not depend on that change.

Regression test

• Added a focused classifier regression for Deno's shortened not a dependency wording.

Verification

• Focused RED then GREEN: 1 test, 29 steps
• src/extensions suite: 78 tests, 510 steps
• Full unit suite: 3786 tests, 28100 steps, 1 ignored
• deno fmt --check: 4980 files
• deno lint: 4905 files
• deno check src/index.ts
• 21/21 scaffold, install, and production build matrix passes when paired with PR fix(transforms): resolve server-side esm.sh modules with a server target #3541

📝 Walkthrough

Walkthrough

The missing-module parser now accepts Bun/Deno messages without an import-map clause. A test verifies that the parser recognizes a matching missing first-party package.

Changes

Missing dependency parsing

Layer / File(s)	Summary
Parser update and test coverage src/extensions/first-party-import.ts, src/extensions/first-party-import.test.ts	The parser accepts both missing-dependency message forms. A test covers the shorter Deno-style message and matching package identifier.
