`mcp doctor --format` and `--format=` reported VALIDATION_ERROR
"Invalid output format: missing", although docs/cli.md documents
MISSING_OUTPUT_VALUE for valued output flags without a value and
`capabilities` already returns it. Classify absent and empty values as
missing, share the existing missing-value message, and keep
VALIDATION_ERROR for a present but unsupported format.
Fixes#6455

Deliver complete Evidence directly through MCP with required nullable analysis profiles and immutable per-server delivery settings. Bind selected environments at construction and require typed cleanup outcomes with retained retry ownership.
Remove test-only routing, duplicate session and snapshot metadata, producer-field repairs, and ambiguous provider arguments. Separate artifact byte identity from occurrence classification and retain typed source-map and partial native facts across CLI, MCP, and verifier consumers.
BREAKING CHANGE: obsolete Evidence envelopes, session aliases, incomplete snapshots, and missing normalized producer facts are no longer accepted.
Parses rea mcp doctor arguments against one zod option schema that is also the help renderer's source of truth, answering --help/-h in any position without starting a diagnostic session and keeping actionable errors for unknown options and invalid formats. Updates the landed help assertion to the schema-rendered format list and adds boundary coverage for help positioning and --format edge cases.
