Add renameGear() function to rename fishing gears in MizerParams

[Copilot]

Adds renameGear() function to rename fishing gears, mirroring the existing renameSpecies() functionality.

Implementation

• New function renameGear(params, replace) in R/manipulate_species.R

  • Updates gear names in gear_params data frame
  • Updates gear dimension names in selectivity and catchability arrays
  • Updates gear names in initial_effort vector
  • Validates gear names exist before renaming
  • Validates resulting params object

• Tests in tests/testthat/test-manipulate_species.R

  • Verifies all gear-related slots update correctly
  • Verifies effort values preserved
  • Tests error handling for non-existent gears

• Documentation following existing patterns

  • Roxygen2 documentation with experimental lifecycle badge
  • Updated NEWS.md

Usage

replace <- c(Industrial = "Trawl", Otter = "Beam_Trawl")
params <- renameGear(NS_params, replace)
gear_params(params)$gear

Note: NAMESPACE and man files will be regenerated by devtools::document() during the package build process.
