Subset an intervs_mat preserving interval identity

Description

Row subset of an intervs_mat subsets attr(., "intervals") in parallel. Column-only subset leaves the intervals attribute unchanged. Single-row results with drop = TRUE return a plain numeric vector (class dropped).

Usage

## S3 method for class 'intervs_mat'
x[i, j, ..., drop = TRUE]

Arguments

`x`	an `intervs_mat`
`i`	row selector (logical, integer, or character matching rownames)
`j`	column selector
`...`	unused
`drop`	if `TRUE` and a single row is selected via `i`, collapse to a named vector and drop the class. Defaults to `TRUE` to match base matrix `[` for row selection. Column-only subsets (`i` missing) are never dropped to a vector, even if `j` selects a single column - this preserves the row-interval correspondence.
