Add HelioAI to the project list

[erdoganfurkan]

This PR adds HelioAI to the PyHC project list.

HelioAI is an AI agent for heliophysics and space plasma physics. It resolves natural-language descriptions to parameter identifiers across 70+ missions using hybrid semantic and lexical retrieval over the speasy catalogue, downloads the data, runs the analysis in a sandboxed Python environment with PlasmaPy-based tools and cited method recipes, and exports each session as a self-contained, re-runnable Jupyter notebook.

Self-review against the six standards — five "Good", one "Partially met":

Standard	Grade	Basis
Community	Good	Public development, Contributor Covenant 2.1, contribution guidelines that state in advance what will not be accepted
Documentation	Partially met	Live MkDocs site built in --strict mode, guides and developer docs, 99% of public objects documented — but docstring Args:/examples reach only 35%/23% of the public surface, short of standard 8
Testing	Good	797 tests, 79.7% measured coverage with no exclusion list and a 70% enforced floor, CI on Linux/macOS/Windows across Python 3.12–3.14
Software Maturity	Good	Installable package released to PyPI via trusted publishing, semantic versioning, ruff for style and static analysis
PHEP 3	Good	Python 3.12/3.13/3.14 tested, core dependency floors within the 24-month window, heliophysicsPy/pyhc-actions/phep3-compliance green in CI
License	Good	MIT, OSI-approved

The Documentation grade is deliberately orange: an evaluation run against the PyHC standards found docstring examples covering 23% of the public API, which does not meet standard 8's requirement for all functions and classes. Completing the Args:/Returns:/Example: sections is the next documentation task, tracked for a 0.2.x release.

Happy to adjust the entry — keywords, description, or grades — if anything looks off.

Thank you for your submission, @erdoganfurkan! Sounds like a cool project. Just wanted to let you know I've seen this, but I may not get around to reviewing it for another week or so.

Thanks again, @erdoganfurkan!

 I reviewed this package and I think it’ll make a great addition to PyHC. I agree with your self evaluation so I’m merging this PR as-is.

HelioAI will now be included in PyHC’s Projects page, our shared PyHC Environment, and our PyHC-Chat AI repo.

Additionally, I wonder if you’d be interested in presenting this at one of our upcoming biweekly telecons? (See the calendar on pyhc.org) I know I’d like to hear more about HelioAI and see it in action, personally, and I’m sure our community members would be interested too. If that appeals to you, our PI Julie could reach out.

Thank you, @sapols ! Glad it fits, and thanks for the review.

Yes, I'd be very happy to present HelioAI at one of the upcoming telecons. A live demo is exactly the format I'd want for it: the interesting part is watching an actual session resolve a natural-language question to real mission data and come out as a re-runnable notebook, which doesn't come across in a slide deck.

Please do have Julie reach out. I'm flexible on the date. I'm currently working on 0.3.0, so a slot a few weeks out would let me present it with what's new in it.
