refactor: rename project uatu -> sanderling (#24)

* refactor: rename Go module path uatu -> sanderling

Module path github.com/priyanshujain/uatu -> github.com/priyanshujain/sanderling,
including all imports and the proto go_package option. Generated .pb.go files
rewritten in-place; safe to regenerate with protoc later.

* chore(proto): regenerate driverpb after module path rename

The previous sed-based module rename corrupted the embedded descriptor
byte lengths. buf generate rewrites them cleanly.

* refactor: rename CLI binary uatu -> sanderling

Updates Makefile target + UATU_BIN var, .goreleaser project/build IDs,
.gitignore comment, and all user-facing strings in the CLI help text,
error messages, and tests. Binary is now bin/sanderling.

* refactor(sdk): rename Kotlin package dev.uatu.sdk -> dev.sanderling.sdk

Moves sdk/android/src/{main,test}/kotlin/dev/uatu -> dev/sanderling and
rewrites package declarations, imports, and the Gradle namespace. Class
names (Uatu, UatuRuntime) are renamed in a follow-up commit.

* refactor(sidecar): rename Kotlin package dev.uatu.sidecar -> dev.sanderling.sidecar

Moves sidecar/src/{main,test}/kotlin/dev/uatu -> dev/sanderling and
rewrites package declarations, imports, and the application mainClass.

* refactor: rename Uatu API surface -> Sanderling

- Kotlin: Uatu -> Sanderling, UatuRuntime -> SanderlingRuntime (+ files).
- JS host binding: globalThis.__uatu__ -> __sanderling__ (Go verifier,
  spec-api, tests).
- TS interface: UatuRuntime -> SanderlingRuntime; internal tags
  __uatuFormula / __uatuActionGenerator -> __sanderling* variants.
- Go trace: UatuVersion field + uatu_version JSON tag renamed.
- Socket naming: uatu-agent / uatu-agent-reader -> sanderling-agent*.
- Sample app, docs, inline-JS test strings updated to match.

* refactor(examples): rename examples/folio/uatu -> examples/folio/sanderling

Renames the example spec directory; updates justfile paths + gitignore
entries accordingly. Package.json name/description and @uatu/spec
dependency are renamed in the npm + docs commits.

* chore(build): rename gradle property + rootProject.name uatu -> sanderling

- Renames the uatu.version gradle property and all its -P references in
  Makefile, build.gradle.kts files, and .github/workflows/release.yml.
- settings.gradle.kts rootProject.name = "sanderling".
- Renames .env.local.example header + release-cli workflow job name.

* refactor(proto): rename proto package uatu.driver.v1 -> sanderling.driver.v1

Updates the proto package and java_package, regenerates driver.pb.go +
driver_grpc.pb.go, rewrites Kotlin imports and the gRPC ServiceName
assertion in driver_test.go.

* refactor: rename npm package @uatu/spec -> @sanderling/spec

Renames package name in pkg/spec-api/package.json + lockfile, all
consumer imports (examples/folio spec, testdata, verifier tests), the
esbuild alias in cmd/sanderling/test_run.go, and related doc references.

* docs: rename uatu -> sanderling in README, docs, and URLs

- README + docs/{manual,development}/*: narrative + GitHub + Pages URLs.
- POM + npm package.json repo/homepage/bugs URLs.
- .gitignore + embed_stub + Makefile-comment references updated to
  'make sanderling'.
- Minor narrative comments in cmd/sanderling/test_run.go and
  internal/inspect/server.go.

* refactor: rename remaining internal uatu strings -> sanderling

- SANDERLING_TEST_PHONE/OTP env vars (cmd + bundler tests).
- sanderling-sidecar runtime tmp dir + extracted JAR filename.
- Inspect web UI: @sanderling/inspect-web package, title, theme
  localStorage key, RunList empty-state copy, uatu_version TS field.
- Sample app storage key sanderling.ledger.v1.
- Test data: sanderling_test AVD name + com.example.sanderling_test.
- Release docs tarball name template.
