I did the market research last, but I’ll present it first! I didn’t find any ready made lens that would satisfy me: 90 or more degrees wide, 0.1 or more numerical aperture when focused closer than 1:1. I found many systems almost suitable, most typically in the form of a probe lens: a small objective mounted on top of a long relay system. Some of which allow very close focus and wide angle of view.
A common small wide angle objective is mounted on Endoscopes and Borescopes, there are many types and qualities; typically are expensive items, and I couldn’t find many data about objective specifications, like aperture, focal length, close focus and resolution. From brochures, appear that the resolution is usually below FHD. An optical scheme is illustrated in the fantastic lectures by Gross, slide 14: https://www.iap.uni-jena.de/iapmedia/DCS17_Design+and+Correction+Lecture+11+Correction+principles+II-p-20002675.pdf
Chip On the Tip probes and small digital microscope have a small sensor with the objective mounted directly on the tip of the borescope; this substitutes the probe lens design while keeping the same form factor. This design is interesting and allow high magnification with a very economic system. A common application is found on mobile phone cameras, a very small objectives with entrance pupil placed on the front; wide angles are common and the image quality is good. They don’t really reach macro magnifications, but thanks to the small size of the sensor, the resulting image can be a strong close-up. There are many phone lens attachments; the wide-angle ones expand the view, but with no improvement in close focus, and more or less noticeable image quality degradation. Macro lens attachments allow very close focus and can be sharp while keeping the wide angle.
There are several models and manufacturers of surveillance and inspection pinhole probe lenses; some of which may allow close focus. However the image resolution seems more or less capped at 1 Megapixel. Among the many, Marshall Electronics has a wide range of pinhole models, and even a Pinhole wide angle attachment lens, that screws in front of a camcorder lens. http://www.marshall-usa.com/optical/lenses/#pinhole
There are also M12 lenses with pinhole design; they allow narrower profile and closer focus, but not so wide or corrected as the fisheye. Using those objective as tip objectives has been explored extensively by amateurs. One “pro” (paid) application is by Attenborough and Dohrn to shoot a BBC documentary about ants. For filming in macro from inside the ants nest, they put together this “Frankencam” probe https://www.bbc.co.uk/programmes/p05rgmbt/p05rglmw
The front objective is a humble M12 wide angle pinhole lens, with virtual forward pupil, followed by a couple of larger lenses for relay. The sensor used had 4K resolution, but the pinhole objective most likely did not actually filled it. The footage presented in the documentary came out nice though.
For cine production, there are at least three companies providing probe lenses with high image quality; usually those consist on a relay and rotatable system, on top of which different objectives can be mounted; macro included. The systems are professional grade, very expensive. Panavision has the original name of Frazier lens, one of the pioneers in using probe lens for documentaries. https://www.panavision.com/products/macro-and-specialty-lenses. Innovision manufactures its probe system, http://www.innovision-optics.com/lenses.shtml. Vantagefilm distributes at least three different probe systems, the T-Rex Superscope, a CPT snorkel and an ISCO Specimage macro system. They have also a 2mm mini macro, likely an industrial probe lens adapted for large sensor format. https://www.vantagefilm.com/file/edee/2016/01/t-rex-superscope-and-mini-t-rex.pdf
Even more choice for filmaking:

None of the listed cine systems has a dedicated super-macro lens attachment; if this lens is to be found, it will be simple to adapt it to each of the probe systems.
For more custom applications, I’m sure that a large variety of wide angle, close focus systems have been realized. I didn’t search too extensively; look for example at the broad range of Opto Engineering https://www.opto-e.com/products/optics. They may have one interesting close focus, high resolution borescope.
I report here a nice example of probe lens from a young and then unknown Al Nagler: http://cs.astronomy.com/asy/b/astronomy/archive/2015/10/13/the-evolution-of-eyepiece-developments-at-tele-vue.aspx
Apart from the prisms and the voluptuous relay lenses, the main objective design is a nice example of wide angle, almost-forward pupil. The T-Rex cine system linked above has likely a nearly identical system, derotator prism included; but misses the sapphire scanning unit.
Probe lenses have been developed for use with SLR cameras; here an example of peep-through-hole objective from the DDR. Note the forward-pupil objective at the end, and the physical aperture in the middle of the 1:1 relay lens. The objective and the relay are designed together, so ray fans coupling and aberrations are optimized. http://www.marcocavina.com/articoli_fotografici/Zeiss_cute_DFR_DDR_lenses/00_pag_English.htm
The only probe lens available commercially for consumer cameras today is the Laowa 24mm f/14 probe lens, launched in 2018 https://www.venuslens.net/product/laowa-24mm-f-14-2x-macro-probe/. It is a ready-made solution that fits the bill. It is constituted by a short focus, wide angle lens at the end, followed by a Hopkins borescope light guide and double relay system. It allows up to 2:1 macro with a wide angle of 85 degrees; this feat comes by placing the entrance pupil almost at the front end of the lens. This design is like a scaled-up borescope. Has a very modest nominal aperture of f/14, but when at 2:1 macro, the front objective likely works at 2:1 aperture, f/7 (NA~0,07) thus it is capable of providing high resolution. The objective keeps the wide angle constant also at such close focus. I have found no technical test of this lens, and don’t own one either, so I just guess that it works properly. Focus and Iris are manual.
And at the end, when I was thinking to know everything, I got tired of Google and set DuckDuck as search engine. A simple search returned me the INON amazing range of products, included a bug’s eye objective released in 2011. I was terrified! Oh no, they’ve done that before! I’ve wasted all this time! Luckily not; the probe system they make is really nice, but the claimed bug’s eye objective is more a wide angle attachment with no strong macro capability (they seem to state max magnification 0.15; or is it the wide-angle adapter de-magnification?); while their similar relay lens does not seem too different from the M12-over-macro DIY system, apart for waterproofness!
A further update, the probe lenses made by H Jay Margolis at Infinity optics of Colorado, US. The systems were developed for use as microscopes, and have been extended to a longer focus. It may be the best modular probe system on the market today. They do not offer wide angle lenses, but have a very interesting “spherical aberration compensation”, like the one seen in modern macro lenses. The Robusto probes even have an Exclusive, Innovative and Revolutionary… Variable Iris! Well, just as all photographic lenses since 200 years.
The name is Infinity optics, but the objectives are not infinity-corrected! Actually the opposite, they seem to be accurately compensated for various focusing distances. I coudn’t find any optical scheme, here below one of their nice modular setup
