Migrate three pure-function modules from Elixir to Gleam: - polling_offset: deterministic hash-based polling offset (pure Gleam, no FFI) - changelog_parser: text parsing logic in Gleam, thin Elixir wrapper for File I/O - user_agent_parser: regex-based UA parsing in Gleam with Erlang FFI for atom-keyed map conversion Add gleam_regexp dependency for regex support in Gleam modules. Update all call sites and tests to use Gleam module atoms. Reviewed-on: graham/towerops-web#103
