Wrap ConfigParse.jsonc() and ConfigParse.effectSchema() calls in
loadConfig with Effect.catchCause to prevent sync-thrown JsonError
and InvalidError from becoming Effect defects. On parse/schema
failure, the bad file is skipped with a log.error and {} fallback
instead of crashing, matching the existing tui.jsonc error handling
pattern in tui.ts.
Without this, any invalid JSONC syntax or schema violation in
opencode.json/opencode.jsonc causes "4 of 6 requests failed:
Unexpected server error" on startup. Now the server starts with
default values and logs the config error details.
Fixes anomalyco#29200

Code Review
This pull request introduces a significant architectural shift and UI overhaul across the OpenCode platform. Key updates include migrating the desktop application from Tauri to Electron, implementing a new tab-based navigation and composer design for non-production environments, and adding a referral reward system to the console. The codebase underwent a major refactoring to rename global SDK and sync providers to server-specific contexts, alongside infrastructure updates to monitoring and deployment regions. Review feedback highlights a critical accessibility concern regarding hidden streaming content, warns against breaking changes in custom provider configurations due to consolidated placeholders, and recommends using reactive state over direct DOM access in the prompt input component.

- When config parsing/schema decoding fails,
datafalls back to an empty decodedInfo, but the function still proceeds to the$schemaauto-injection block. This can overwrite an invalid config file (or duplicate an existing$schemakey) even though the file couldn't be parsed/validated, which is potentially destructive and can further corrupt the user's config.
Consider short-circuiting on parse/validation failure (e.g., return early for path sources) or tracking a parsedSuccessfully flag so plugin resolution and $schema auto-write only run when parsing/validation succeeded.

const parsed = ConfigParse.jsonc(expanded, source)

log.error("invalid config", { path: source, cause })
return Schema.decodeSync(Info)({})
}),
