[Bug]: GitHub Enterprise host is ignored — auth resolution and sync are hardcoded to github.com

Preflight

• I searched existing issues and this isn't a duplicate
• I'm on the latest version (or I've noted my version below)

What happened?

I have gh logged into two hosts: github.com (personal) and a GitHub Enterprise Server instance. When working with OpenKnowledge, ok uses my public github.com identity even when the workspace's git remote points at the enterprise host. I expected ok to resolve credentials/identity for the host the repo actually lives on, and I couldn't find any config key or env var to change the default host.

Digging into the source, the --host flag on the ok auth subcommands is host-aware, but several core paths are hardcoded to github.com:

• packages/cli/src/auth/resolve-auth.ts:42 — resolveAuth calls detectGh() with no host, so gh auth token returns the default (github.com) token and Tier A wins even when the repo's remote is a GHES host.
• packages/server/src/sync-engine.ts:68 — SYNC_GH_TOKEN_HOST = 'github.com'; the gh token relayed into every sync git subprocess (OK_GH_TOKEN/OK_GH_TOKEN_HOST) is always the github.com one.
• packages/server/src/sync-engine.ts:865,876 — the push-permission probe passes host: 'github.com' unconditionally.
• packages/server/src/share/git-context.ts:168-191 — parseGitHubOriginUrl only matches github.com remotes; enterprise remotes classify as non-github, downgrading the push-permission check to unknown.
• packages/app/src/lib/transports/auth-query-transport.ts:25 — the app UI always queries auth status/repos for github.com, so it displays the public profile regardless of the workspace's remote.

Suggested direction (happy to open a PR):

1. Thread the host parsed from the workspace's origin remote into resolveAuth/detectGh instead of defaulting to github.com.
2. Derive SYNC_GH_TOKEN_HOST and the push-permission probe host from the repo's origin host.
3. Widen parseGitHubOriginUrl to recognize GHES hostnames.

Steps to reproduce

1. gh auth login on both github.com and a GitHub Enterprise Server host.
2. Open (or sync) an OpenKnowledge workspace whose git origin points at the enterprise host.
3. Observe that auth/identity (sync token relay, push-permission check, profile shown in the app) resolves to the github.com account instead of the enterprise one.

Platform
