Release v5.2.8 (#3375)

Upgrades to Better Auth 1.7, expands Custom Styles coverage of item headers, and adds a human-approval step to the AI agent's resume edits.

Breaking for self-hosters using a custom OAuth provider: the callback path changes from /api/auth/oauth2/callback/custom to /api/auth/callback/custom, and installs using OAUTH_DISCOVERY_URL need one additional UPDATE after upgrading. Both are documented in docs/self-hosting/sso.mdx.

- Better Auth 1.7, with the account issuer migration and the jwks alg/crv columns the 1.7 jwt plugin requires
- Agent edits gated behind an approval step, with crash-safe runs and context pruning
- item-header now covers every section header row on every template; adds the item-header-row part
- Fixes provider unlinking, auth error messages, and version conflicts on freshly created resumes
- New /auth/error page, translated across all 53 target locales
- DeepSeek Harness plugin moved into packages/dsh-plugin
- Dependency bumps across the workspace
