feat: finish interpreter (#595)

# Description

Finish Ipld <=> Wit interpreter across all available Val/Types. 

fix: handle ints as floats in the interpreter (when given a float Wit
type).

Includes
  - skip notifications when there are no receivers
  - add logging in wasm/guest-fn test to web server integration test
- update Homestar-function(s) to use cargo-component 0.9 and update for
breaking changes
  - readme updates around cargo-component
  - const recursion/grow-only defaults for stacker
- remove most pattern-matching guards and move to nested matches in the
interpreter
  - newly generated test wasms (= cid updates)
  - move to location/module-path in logs (from updated tracing-logfmt)

## Closes

- Closes fission-codes/stack#155.
- Closes #61 and "finishes" our WIT <=> IPLD interpreter.
