state-spaces/mamba#771 GitHub Actions CI using EC2 GPU nodes

This PR adds 4 GitHub Actions workflows that install or test mamba_ssm on EC2 GPU nodes (using [Open-Athena/ec2-gha]):

install.yaml: install mamba_ssm on an EC2 GPU instance (default: [g4dn.xlarge])
installs.yaml: run install.yaml on 6 recent versions of Mamba (2.2.{0,1,2,3post2,4,5})
test.yaml: run mamba_ssm tests on an EC2 GPU instance ([g5] or [g6] series)
tests.yaml: run test.yaml on HEAD, on a g5.2xlarge and g6.2xlarge

.vimium-rc

[Vimium] configs

Import vimium-options.json into the extension's settings page.

For reference, here's the extracted keyMappings section:

$ cat vimium-options.json | jq -r .keyMappings
# Insert your preferred key mappings here.

⌘ (Command): Place of Interest Sign
⌥ (Option): Option Key
⌃ (Control): Up Arrowhead
⇧ (Shift): Upwards White Arrow

I can never remember how to get the "command" emoji ⌘ in the cmd-ctrl-space unicode picker:

This UX was always bad, but some recent (2024?) macOS update made it even worse 😵‍💫.

`hash-files.py`

Standalone script that mimics [GitHub Actions' hashFiles helper][hashFiles docs] ([used by actions/setup-python][PipCache], and frequently with [actions/cache])

Upstream hashFiles source is [here][hashFiles source], this script was written while debugging [setup-python#919].

Examples

git clone https://gist.github.com/ryan-williams/2e616363c68072bf67cad675fcb18f3b hashfiles-gist
export PATH=$PATH:$(pwd)/hashfiles-gist

`watchman` basic example

I found the watchman docs hard to follow / bereft of useful examples. Below is my attempt at a quickstart guide; see ryan-williams/watchman-helpers for some aliases and other scripts.

0. Install watchman
1. Configure a "watch" on the current directory
- 1b. List currently watched directories
- 1c. Remove a watched directory
2. Set up a "trigger": continuously run a command in response to changes
- 2a. rsync a directory to a remote host
Is there a simpler way to trigger on all files?
