v0.14.1

- `ANDROID_LAB_EMULATOR_MEMORY_LIMIT` overrides the emulator memory cap. `start` accepts a whole number followed by `m` or `g` and rejects anything else.

- The emulator container's memory cap is 12g instead of 8g. A 4 GiB guest with software rendering holds about 7.4 GiB, so long test runs hit the 8g cap and the kernel killed the emulator mid-run.

- A running lab keeps its old cap until `android-lab restart` recreates the emulator with this release.

- The README and the installer's usage comment write `<version>` and show how to pick a release from the tags, as the `android-lab` skill already does. A release now changes only `VERSION`.
