Update Skill Tree for 0.5

[jay9297]

Confirm scope

• This is a single, well-scoped task (not a broad refactor or multi-feature request)
• I've checked there are no open PRs already addressing this

What needs to be fixed or done?

Need to pull the latest Skill Tree JSON and implement the nodes missing from the current tree as well as update all existing nodes with the new data. Tree JSON can be found here: https://github.com/grindinggear/poe2-skilltree-export/releases/tag/0.5.0

Acceptance criteria

• No regressions
• New tree nodes properly added and present
• New Ascendencies properly added and present (create follow up AI Fix issues to implement new skills from these ascendencies if complex and in need of new calculations)

PoB build code (if relevant)

⚠️ AI Fix Failed

The apply-fix job failed after exhausting all agent tiers and retry cycles.
This likely indicates an API outage or expired credentials.

What to check:

• CLAUDE_CODE_OAUTH_TOKEN — is the Pro subscription active?
• OPENCODE_API_KEY — is the key valid?
• EMERGENCY_ANTHROPIC_API_KEY — set this secret for last-resort fallback.

Re-add the ai-fix label once credentials are restored to retry.
