## libforge changelog

Commits brought in
([`f0706e1...7fc3b2c`](fil-forge/libforge@f0706e1...7fc3b2c),
newest first):

-
[`7fc3b2c`](fil-forge/libforge@7fc3b2c)
Fix DID verification method ID encoding and add controller (#48) — stops
the `#key-0` fragment from being double-encoded to `#%23key-0`, and sets
the verification method `controller` to the document DID.
-
[`f06be16`](fil-forge/libforge@f06be16)
fix: correct DID verification method fragment and set controller — the
underlying fix landed in #48.
-
[`aba2bd2`](fil-forge/libforge@aba2bd2)
feat: add `/ucan/revoke` command (#47).
-
[`aac837a`](fil-forge/libforge@aac837a)
add space to blob remove, abort, and reject — makes `/blob/abort` carry
a required `Cause`, adds `/blob/reject` (upload service → storage node)
as the mutually-exclusive counterpart to `/blob/accept` for unwinding a
parked blob.
-
[`a3aa293`](fil-forge/libforge@a3aa293)
fix: make bucket optional.

## Changes

- `go.mod` / `go.sum`: only the `libforge` require line and its
checksums changed — no transitive dependency changes.

## Verification

- `go build ./...` — passes
- `go vet ./...` — passes
- `go test ./...` — all packages pass
