v1.4.0 - Per-Run Environment Injection

This minor release adds per-run environment variables to RunOptions, so callers can set environment for a single claude child process without mutating the parent process environment.

Highlights

  • Adds RunOptions.Env map[string]string. Entries are merged over the inherited parent process environment, and a per-run key supersedes an inherited value so the child sees exactly one value per key.
  • A nil or empty map leaves the child environment untouched, identical to prior behavior.
  • Applies the override at every exec site that launches the CLI: RunPromptCtx, RunFromStdinCtx, the stream-json path, and the dangerous subpackage.
  • Unions DefaultOptions.Env with a per-run Env, with the per-run map winning on conflict.
  • Adds ApplyEnv, an exported helper the dangerous subpackage reuses for identical merge semantics.

Compatibility Notes

  • The public API is additive. Existing callers that never set Env keep the current behavior of inheriting the parent environment wholesale.
  • The parent process environment is never modified.

Verification

  • just release check
  • go test ./...
  • go test -race ./pkg/claude/...
