fix(javascript)!: avoid endpoint payload copies in graph metadata (#1423)

Keep exact endpoint observations and request properties while using compact display labels and collision-safe canonical value digests for long artifact-local endpoint keys. Verify real CLI/stdio MCP tracing and version comparison without truncating evidence.

BREAKING CHANGE: New analyses use compact endpoint labels and digest-based IDs for long or reserved-prefix endpoint keys. Select IDs from the parent graph and read full values from endpoint properties. Previously stored graphs retain their original identities and remain valid workflow inputs.
