Thank you! https://www.amazon.com/dp/B06XXZW951/ref=cm_sw_r_other_apa_08S8Bb0N8T08K?th=1&psc=1
Thanks for making my life more difficult. I was gearing up to get the ThruNite Neutron 2C after all the earlier recommendations, but that UltraTac K18 scratches my EDC itch and can handle alkaline batteries until I get some 10440s and a charger. Now I've got choices to make...
I find twisty switches always turn on in my pockets, but those are always the smallest options. The narrowest lights that can do 100 lumens are listed here. Some highlights that meet your brightness and runtime requirements:

I recommend the UltraTac K18.
How loose/tight-fitting is your clothing, and how much do your pockets show beneath your shirt? That's going to affect how large the light can be before you or others notice it. For some people and their style of dress, a light that runs on an 18650 battery wouldn't be noticeable, while others would need a AA or even AAA sized light.
AAA/10440 Lights
If you're interested in not having the light visibly print in your pocket at all, like I was in choosing an EDC, and your clothes are relatively slim fitting, you're probably going to want a AAA/10440 sized light (10440 is the lithium ion version of a AAA sized battery, and produces brighter output but less runtime than a typical AAA alkaline, NiMH, or lithium primary battery).
I went with the Folomov EDC C1. It's got a coated brass body, warm light, and very high CRI (meaning it helps show colors better than low CRI lights). It clips tightly inside the front pocket or coin pocket and takes up very little space. I've been very much enjoying mine without issue, though others have had quality control issues where the emitter burnt out or developed a dead spot, so unless those issues are sorted out, your mileage may vary.
If you want something in the AAA size specifically from Amazon, the Ultratac K18 would probably serve you quite well.
AA/14500 Lights
If you're willing to go up to AA/14500 sized light, the Thrunite Archer 1A V3 might be a good choice. Runs on either AA or 14500 battery. Has a sub-lumen firefly mode for preserving night vision, and goes up to 200 lumens with a AA battery. I don't know how much brighter it would be with a 14500 battery, but you can typically expect two to three times brighter, though with shorter run times. 200 lumens is typically enough for most tasks, though you might appreciate the extra brightness if you were looking around outdoors.
18650 Lights
If you're willing to go up to an 18650 sized light, the Thrunite TC15 would likely be a great choice. It gets incredibly bright for a 1x 18650 light, at up to 2300 lumens, but has well spaced lower modes for everyday use as well. It looks like currently only the cool white version is available on Amazon it. Most people, myself included, prefer neutral to warm white because it looks better, and produces less backscatter in particulates in the air.
I think a little more information about your intended use of the light and how you'd like to carry it would help us make good recommendations. Good luck on the search!
EDIT: Also, another user asked a good question about what you mean by "rechargeable." Do you mean that you just plug the light in without taking the battery out, or do you mean the battery is rechargeable and you can put it in a charger? There are plenty of excellent chargers at places like illumn.com that will open up a whole new realm of possibilities for flashlights, so the small up-front investment is usually worth it.
Thanks man! https://www.amazon.com/dp/B06XXZW951/ref=cm_sw_r_other_apa_08S8Bb0N8T08K?th=1&psc=1
