OPENCODE_CONFIG_DIR does not read custom config file.

[nitg16]

Description

Config file opencode.json stored in OPENCODE_CONFIG_DIR does not work when doing this:

export OPENCODE_CONFIG_DIR=~/data/opencode

Config file opencode.json stored in OPENCODE_CONFIG_DIR works only when exporting both:

export OPENCODE_CONFIG_DIR=~/data/opencode
export OPENCODE_CONFIG=~/data/opencode/opencode.json

Ideally OPENCODE_CONFIG_DIR env var should be enough to load custom config from a custom config directory.

OpenCode version

/oc please fix this, read config.ts update this:
if (Flag.OPENCODE_CONFIG_DIR) {
directories.push(Flag.OPENCODE_CONFIG_DIR)
log.debug("loading config from OPENCODE_CONFIG_DIR", { path: Flag.OPENCODE_CONFIG_DIR })
}

const promises: Promise<void>[] = []
for (const dir of directories) {
  await assertValid(dir)

  if (dir.endsWith(".opencode")) {
    for (const file of ["opencode.jsonc", "opencode.json"]) {
      log.debug(`loading config from ${path.join(dir, file)}`)
      result = mergeDeep(result, await loadFile(path.join(dir, file)))
      // to satisy the type checker
      result.agent ??= {}
      result.mode ??= {}
      result.plugin ??= []
    }
  }

To also read opencode.json/opencode.jsonc if the dir is the flag dir
