What does this PR do?

This PR adds the ability to use regex patterns to whitelist/blacklist provider models in the config.

Before:

  "provider": {
    "opencode": {
      "blacklist": [
        "claude-3-5-haiku",
        "claude-haiku-4-5",
        "claude-opus-4-1",
        "claude-opus-4-5",
        "claude-opus-4-6",
        "claude-sonnet-4",
        "claude-sonnet-4-5",
        "claude-sonnet-4-6",
        "glm-4.6",
        "glm-4.7",
        "glm-4.7-free",
      ],
    },

Now:

  "provider": {
    "opencode": {
      "blacklist": [
        "/claude/", // all claude models
        "/glm-4(\\..*)?$/", // all glm 4.x models
      ],
    },

How did you verify your code works?

I updated my config, ran the code in my local using bun dev and verified that the regex patterns in blacklist/whitelist in opencode.json file are getting picked up.

Based on my search results, I found one potentially related PR:

Related PR:

• feat: add configuration field to enable and disable models for standartisation #18899: "feat: add configuration field to enable and disable models for standartisation"
  • This PR appears to address model filtering/selection configuration, which is related to the whitelist/blacklist functionality being added in PR feat(opencode): use regex to whitelist/blacklist provider models #23283.

However, this is not an exact duplicate as PR #23283 specifically adds regex pattern support to the existing whitelist/blacklist functionality, while #18899 focuses on an enable/disable configuration field.

No other duplicate PRs were found that directly address the same regex whitelist/blacklist feature.
