refactor(javascript): consume normalized feature seeds

Require parsed seed facts in the pure trace projection and leave raw request defaults at the shared workflow boundary. Remove the redundant seed parse, unused raw-seed alias and duplicate seed-match binding.

Move omitted-versus-explicit defaults and full Evidence identity checks to compiled CLI/MCP acceptance. Reuse the owned MCP fixture and request files in the tests. Matching, native handoff, empty-literal, coverage and immutability checks remain covered; public schemas and successful outputs are unchanged.
