v1 seed parser: let/return/for initializers cannot continue onto the next line (missing skip_newlines)

[gunbai-bot]

Summary

The v1 seed parser did not call skip_newlines before reading required expressions after =, return, and in, so a newline before the value caused parse failure. This PR adds skip_newlines at those four sites in src/v1/02_parse.dag (typed/untyped let, return, for-in) without widening generic parse_expr entry, keeps the generated seed parser in sync, and enrolls durable floor coverage via src/v1/tests/claim/required_expr_newline_continuation_test.dag plus a seed-side oracle in pipeline.rs.

Test plan

• cargo test -p v1-compiler-tests let_return_for_initializer_allows_newline_before_expr — ok
• target/release/regen_stage0 --verify — regen_divergence_count=0
• CI: build, regen, heal, floor (pending on latest auto-heal commit)

Review 46080 (REQUEST_CHANGES — missing regen output): addressed

The finding was correct on ac6cc55: stage0_emit_model.dag registered v1_tests_claim_required_expr_newline_continuation_test.rs but the emitted .rs and lib.rs pub mod were not committed.

Fixed in 7a19c77 (CI auto-heal): emits src/v1/stage0/src/v1_tests_claim_required_expr_newline_continuation_test.rs, adds pub mod v1_tests_claim_required_expr_newline_continuation_test to lib.rs, and syncs the seed parser delta in v1_compiler_parse.rs. Verified locally: regen_stage0 --verify → regen_divergence_count=0.

Review 46166 (REQUEST_CHANGES — duplicate hand-Rust oracle): addressed in ab3960e

Verified: src/v1/tests/claim/required_expr_newline_continuation_test.dag already exercises all eight accept/refuse rows (untyped/typed let, return, for-in, statement boundary, and the three missing-expression refusals). The pipeline.rs test duplicated that parse surface without a ROADMAP row or shrink receipt on its DeleteWith comment, so it is removed rather than scaffolded.

Review 46209 (REQUEST_CHANGES — stale dissolve-on scaffold): addressed

The trigger was already satisfied at four sites. Introduced parse_required_expression_after_separator (fn-body =, typed/untyped let, return) and parse_required_expression_no_brace_after_separator (for … in collection); updated the carrier note to name both authorities; regen verified (regen_divergence_count=0).
