Proxy: Modernize internal packages on stdlib and add unit tests. v7.0.145 (#4667)
Modernizes several `internal/*` packages under the Go proxy, replaces
third-party forks with standard-library primitives, and brings the
test suite from near-zero to high coverage across the touched packages.

Package changes

- **`internal/errors`** — Rewrites the `pkg/errors` fork as a thin
wrapper
  over stdlib `errors`. A single `withStack` struct captures stack
  traces via `runtime.Callers`; `fmt.Errorf("%w", ...)` handles all
  message wrapping. Restores `errors.Is`/`As`/`Unwrap` chain traversal
  (silently broken in the fork) and deletes ~190 lines of stack/frame
  formatting. `Is`, `As`, `Unwrap`, and `Join` are re-exported so
  callers need a single import.
- **`internal/logger`** — Swaps stdlib `log.Logger` for `log/slog` JSON
  handlers with UTC timestamps and custom level labels (`verb`, `debug`,
  `warn`, `error`). Hides `withContextID` (no external callers).
- **`internal/sync`** — Converts `Map[K, V]` from a concrete struct to
  an interface with a `NewMap` constructor for testability.
- **`internal/signal`** — Adds `signalNotify` / `osExit` indirections so
  `InstallSignals` and `InstallForceQuit` can be exercised without real
  OS signals or process termination.
- **`internal/utils`** — Drops deprecated `io/ioutil` and the stdlib
  `errors` alias (the internal `errors` package re-exports what's
  needed).
- **`internal/version`** — No code changes; fully covered by new tests.
