* feat: add PostHog usage analytics to CLI

Add anonymous command-level analytics to browseros-cli using the PostHog
Go SDK. Tracks which commands are executed, their success/failure status,
and duration — no PII or person profiles.

- New analytics package with Init/Track/Close singleton
- Distinct ID resolves from server's browseros_id (server.json), falls
  back to CLI-generated UUID (~/.config/browseros-cli/install_id)
- API key injected at build time via ldflags (dev builds = silent no-op)
- Server now writes browseros_id into server.json for cross-surface
  identity correlation

* fix: address PR review feedback for #603

- Return "unknown" for unrecognized args in commandName to avoid
  sending arbitrary user input to PostHog
- Revert goreleaser to {{ .Env.POSTHOG_API_KEY }} (intentional hard
  fail — release builds must have the key set)
- go mod tidy to fix posthog-go direct/indirect marker
- Add POSTHOG_API_KEY to .env.production.example
