Simplify 32 bit CI workflow & lint, test on Go 1.19-1.22 (#45)

A couple changes to simplify various workflows, plus explicitly testing
on the latest Go versions.

* Enable race on all supported platforms, explicitly set -race= flag
* Move linters-settings below linters list
* Reformat octal integers to latest gofmt style
* Fix comments to strictly follow godoc style
* Disable govet's fieldalignment memory size check on test files
* Test on Go 1.19-1.22, verify 32 bit field alignment on Linux with
latest Go

fix: fix field alignment to avoid panics on 32bit OSes (#44)

Fixes #43

To solve this:
- enabled the `fieldalignment` linter (which is a sub-linter of `govet`)
- ran the `fieldalignment -fix` command to fix misaligned structs that
were non-obvious
- switch from using e.g. `int64` + `atomic.StoreInt64` to using
`atomic.Int64` (etc) and because of this...
- drop Go 1.18 support, and require Go 1.19+ (where the new atomic types
were introduced)
- added a new CI job to test in a 32-bit container (so far just Intel
386, which should catch the same bugs as arm32/etc)
- added some new tests to cover `keyvalue/blob.Bytes`, which was what
was giving me trouble initially

indexeddb: Add tests and fix bugs (#34)

* Move JS .env file to indexeddb, should not be in root
* Update to latest wasmbrowsertest
* Remove redundant and unused code
* Test store.Get/Set, fix missing op record for sets
* Fix indexeddb Set handler not storing delete result
* Upgrade go-indexeddb to fix missing abort handling
* Fix missing parent dir error not returned

Use safejs for JS panic handling, add JS to coverage reports (#31)

Switches to https://github.com/hack-pad/safejs to
properly handle all JavaScript panic scenarios in the IndexedDB FS.

Also adds JS to coverage reports, now that wasmbrowsertest supports JS
coverage profiles: agnivade/wasmbrowsertest#41

NOTE: Drops support for Go 1.16 and 1.17 to use safejs. Requires a minor
version bump v0.x to give adopters a heads up.

* Add .env file for automatic GOOS/GOARCH editor settings
* Handle new req.Listen errors
* Add JS test coverage to report

Implement MountFS on `Sub()` fallback to support non-read operations (#…

…28)

Implements MountFS on `Sub()` fallback to support non-read operations.

Caveat: The `PathError`s returned from `File` operations use their
original `Path` values.

This is a limitation of the current MountFS design, where the returned
File from Open(), OpenFile(), and Create() are returned as-is to support
direct interface checks in client code.

Wrappers would break this behavior and therefore were avoided.

Uses `hackpadfs.Fn()` and skip helpers to detect MountFS supported
operations in `fstest`.

Unblocks #21

Also fixes 2 bugs:
* Fixes `keyvalue.Rename()` when source and destination are the same
file.
* Fixes `hackpadfs.RemoveAll()` failed to remove a file at root.

Update to Go 1.19, test on more versions in CI (#24)

- Lint on Go 1.19.
- Test on more versions of Go: 1.16 through 1.19.
- Fix incompatibilities from Go 1.18 onward, particularly around
`js.ValueOf()` and `js.Wrapper`.
