v0.1.0 — hello, world 🪄

Many sources, one read-only view, no copies. Your AI capabilities are scattered across repositories — personal, work, one per project — and every tool wants a single folder. Copy them together and each copy starts drifting from the day you made it. airfs gives you the folder without the copies.

You write down which repositories a workspace is made of, in order. airfs shows them to you as one directory 📂. Nothing moves, nothing is duplicated, and editing a skill in the repository that owns it changes what every workspace layering it sees — right away, with no sync step to remember. 🔄

• 🥇 Order decides. sources.txt is one path per line, most general first. Two layers both shipping a commit skill? The one declared last wins — and it wins whole, never half of yours stitched onto half of theirs.
• 🕵️ Nothing gets shadowed behind your back. airfs sources prints the resolved list and names every entry that lost, right next to the one that beat it. A workspace you cannot explain is a workspace you cannot trust.
• 🚪 One mount per kind. airfs mount serves agents/, skills/, commands/, and scripts/ together — in the foreground, or with --detach when you want your terminal back. airfs status says what is being served, and airfs umount takes it down, stale leftovers included.
• 🛡️ Read-only, with the kernel enforcing it. No tool, no agent, and no stray mv can write back into one of your source repositories through the view.
• 🐹 Pure Go, so installing is one command. It speaks FUSE over /dev/fuse by itself: no C library, no mergerfs to hunt down, nothing to unpack by hand.
• 🩺 airfs doctor before you file a bug. Mounting needs /dev/fuse and a setuid fusermount3, which no unprivileged process can conjure up. doctor checks both and names the package that provides the missing one.
• 📦 A Go library first, a CLI second. sdk/layerfs is an fs.FS, so your own program can read the merged view in process — no mount, no subprocess, nothing to parse — and fs.WalkDir and friends just work on it.

It is a first release, so: Linux for the mount 🐧 — mounting is Linux-only for now; the Go SDK is plain fs.FS and runs anywhere. Best next step is Get started — about five minutes, ending with a workspace you can keep. 🚀
