Keystore is decoded into /dev/shm (tmpfs, RAM-only) during the build
and cleaned up on exit — never written to physical disk. ANDROID_KEYSTORE_PATH
is now required with no fallback; missing it fails loudly. Dagger CI path
updated to write to /tmp and set ANDROID_KEYSTORE_PATH accordingly.
Also fix check_ci_images.sh: filter out incomplete image tags ending in ':'
that arise from dynamic From("image:"+variable) concatenations.

## Summary
- Downgrades `.fvmrc` from Flutter `3.44.1` back to `3.44.0` — `ghcr.io/cirruslabs/flutter:3.44.1` does not exist on GHCR so every Dagger-based deploy job fails with "not found"
- Extends `scripts/check_ci_images.sh` to also validate the Flutter image derived from `.fvmrc` (previously only literal `From("...")` calls in `ci/main.go` were checked, so Renovate bumps to non-existent images went undetected)
- Updates `.pre-commit-config.yaml` to trigger the `ci-image-exists` hook on `.fvmrc` changes as well as `ci/main.go`
## Root cause
Recent run logs showed:
```
! ghcr.io/cirruslabs/flutter:3.44.1: not found
Error: failed to resolve image "ghcr.io/cirruslabs/flutter:3.44.1"
```
Renovate bumped Flutter to 3.44.1 (#411) but cirruslabs has not published that image — the latest available is `3.44.0`. Same root cause as #409, but the pre-commit guard only watched `ci/main.go`, not `.fvmrc`.
Closes#427

## Summary
- Adds `scripts/check_ci_images.sh`: extracts every `From("...")` image reference from `ci/main.go` and runs `skopeo inspect --no-creds` on each one (manifest-only, no layer pull, no daemon required)
- Adds `task check-ci-images` task in `Taskfile.yml` that runs the script
- Adds `ci-image-exists` hook to `.pre-commit-config.yaml` that fires only when `ci/main.go` is staged (using `files: ^ci/main\.go$` rather than `always_run`, to avoid a network round-trip on every unrelated commit)
- Adds `skopeo` to the Nix devShell so the tool is on PATH when the hook runs via `nix develop --command`
This catches a bad image tag (like `ghcr.io/cirruslabs/flutter:3.44.1` not yet published) at commit time, before the push reaches CI.
## Test plan
- Stage a change to `ci/main.go` bumping a `From("...")` tag to a non-existent version → hook rejects commit with NOT FOUND
- Stage a change with valid image tags → hook prints OK for each image and allows the commit
- Stage a change to any other file → `ci-image-exists` hook is skipped entirely
Closes#407
