chore(skills): sync builtin officecli skills from upstream OfficeCli (c764bb7d) (#522)

## Summary

Sync the builtin officecli skills under
`crates/aionui-app/assets/builtin-skills/` with the latest upstream
OfficeCli `main` (`54d7b0e6` → `c764bb7d`), applied as upstream
**deltas** so the AionUi-local Windows platform-note blocks (#489) are
preserved.

9 SKILL.md files refreshed:
- `morph-ppt`
- `officecli-academic-paper`
- `officecli-data-dashboard`
- `officecli-docx`
- `officecli-financial-model`
- `officecli-pitch-deck`
- `officecli-pptx`
- `officecli-word-form`
- `officecli-xlsx`

No file adds/removes and no non-SKILL.md (reference/asset) changes
upstream this round.

## Verification

Each changed file was diffed line-for-line against upstream `c764bb7d`,
in both directions:
- **Nothing missing** — every upstream line is present.
- **Only addition** — the AionUi-local Windows platform-note block.

No code changes; assets only.

## Test plan

- [ ] CI build (`cargo build -p aionui-app`) — corpus is embedded via
`include_dir!`
- [ ] Skills hub renders the refreshed SKILL.md content for each changed
skill
