Fix main CI: repoint emit-directive manual test import to relocated rust_test module

[briansrls]

Problem

Main CI is red (run 29127250131 at 54e4c19 / #6451): the discovery corpus fails with

src/v2/test/claim/manual/emit_directive_rust_test.dag:7:3: error: name 'rust_emit_directive_emitted_call' not found in module 'v2.extdeps.languages.rust'
src/v2/test/claim/manual/emit_directive_rust_test.dag:8:3: error: name 'rust_emit_directive_target_model' not found in module 'v2.extdeps.languages.rust'

Root cause

#6409 relocated the emit-host test scaffolding (including rust_emit_directive_emitted_call and rust_emit_directive_target_model) from v2.extdeps.languages.rust to the new v2.extdeps.languages.rust_test module. Its move criterion was "consumed only by *_test.dag files" — which correctly included this manual test as a consumer — but the manual test's import block was never repointed.

The break was latent because the manual discovery corpus (src/v2/test/claim/manual) wasn't CI-enrolled until the #6438 discovery flip, and after the flip the affected-set selection skipped the file on intervening PRs. #6451's broad diff pulled it into the selected set and it failed on main.

Fix

One-line: repoint the import to v2.extdeps.languages.rust_test. Both names exist there (defined at rust_test.dag:3327 / :3371); a test importing test scaffolding is exactly the consumer class #6409's criterion sorted into that module.

Swept all other importers of v2.extdeps.languages.rust for names missing from rust.dag — the remaining flags are enum variants (Bits32, PanicOnOverflow, TwoComplementWrap, RustGramBuild1State*), all still defined in rust.dag. This is the only broken import.

Note: the affected-set-falsifier failure at 434f1d3 is a separate infra issue (release-bin build timed out at 45 min), not this resolve error.

Verification

• RED: main CI run 29127250131 (the exact resolve failure above).
• GREEN: local claim_batch --entry src/v2/test/claim/manual/emit_directive_rust_test.dag receipt to follow in a comment.

RED control (pre-fix file from origin/main, same binary, same command):

claim_batch: resolve failed for src/v2/test/claim/manual/emit_directive_rust_test.dag:
src/v2/test/claim/manual/emit_directive_rust_test.dag:7:3: error: name 'rust_emit_directive_emitted_call' not found in module 'v2.extdeps.languages.rust' (imported by 'v2.test.manual.emit_directive_rust')

Identical to the main CI failure (run 29127250131). The one-line repoint is the discriminating variable.
