[config-dir-clarify] docs(readme): fix config dir to ~/.code; clarify ~/.codex precedence

[just-every-code]

Fixes #181

This PR corrects misleading configuration directory references in the README and clarifies precedence between legacy and fork paths.

What changed

• Replace ~/.coder with ~/.code in two spots:
  • Backwards-compat note now reads: "Supports ~/.codex/* (if present) or defaults to ~/.code/*".
  • Auth storage path now references ~/.code/auth.json (still reads legacy ~/.codex/auth.json).

Why

• The code resolves the config home via CODE_HOME/CODEX_HOME, then falls back to:
  • ~/.codex if it exists (backward compatibility), otherwise
  • ~/.code (fork default).
• README incorrectly mentioned ~/.coder, which is unrelated to config resolution.

References

• Implementation: codex-rs/core/src/config.rs (find_codex_home) uses ~/.codex if present, else ~/.code.

Validation

• Ran ./build-fast.sh from repo root; build completed successfully with no warnings or errors.

Impact

• Documentation now matches actual behavior; users won’t be misled about where configuration and auth are stored.

Still doesn't clarify what happens when both of ~/.code and ~/.codex are present, are configurations merged together? Which one wins conflicts?
