chore: bump tinybus to v0.3.6 and tinystoragedrivers to v2.1.1 - #95

This is a dependency-version bump in the root `Cargo.toml`: TinyBus moves from `>=0.1.3, <0.2` to `>=0.3.6, <0.4` (still a caret-style range, still `default-features = false` with the same two features), and four git dependencies are repinned from one commit to another on the same repository. No new dependency is introduced, no feature is widened, no permissions or CI configuration change, and nothing here parses untrusted input. The new revisions point at the same owner/repo as before, so this is a routine pin update. I could not read `vendor/tinybus` from this deployment, so I cannot confirm the 0.3.x API still matches the crate's usage — that is left to the build, which would fail loudly rather than silently. _The code index is behind this pull request (indexed at `f96fcdb08bb6`), so retrieved context may be out of date._

No findings.
