v0.0.5 to v0.0.10: limits sized for applications, not snippets

Six releases in one day, each raising a ceiling a real embedder had hit: a 32 MiB ArrayBuffer, a renewable instruction budget, byte-scheduled collections, a 512 MB heap.

The tag messages read like a bug tracker for a product that had just met its users. v0.0.7 (d69c7b7b) raised the hardened ArrayBuffer ceiling from 1 MB to 32 MiB: "an 8 MB Game Boy cartridge and a single 8.5 s frame of 48 kHz audio were both impossible." v0.0.8 (32680f06) added renewInstructionBudget, because a 50-million-instruction lifetime budget "was a fuse on every long-running embedder." v0.0.9 (d0c783b1) schedules collections on bytes, not only allocation count: "An emulator encoding a 23 KB framebuffer per frame died ninety seconds into a game." v0.0.10 (ddbf7cd9) sized the instance ceiling at 1 GB and the heap budget at 512 MB.
