feat(analytics): add Google Analytics and Google Search Console commands

[haresh-seenivasagan]

Motivation

I wanted to give my companies Claw🦞 access to Google Analytics and Search Console data for SEO audits and traffic analysis.

Summary

Command	What it does
gog analytics accounts	List GA4 account summaries (--all for pagination)
gog analytics report <property>	Run a GA4 report (dimensions, metrics, date ranges)
gog searchconsole sites	List Search Console properties
gog searchconsole query <siteUrl>	Run Search Analytics queries

Both read-only. Aliases: ga, gsc.

gog analytics accounts --all --json
gog analytics report 123456789 --from 7daysAgo --to today --dimensions date,country --metrics activeUsers,sessions
gog searchconsole sites
gog searchconsole query sc-domain:example.com --from 2026-02-01 --to 2026-02-07 --dimensions query,page --type WEB

Follows existing patterns (collectAllPages, tableWriter, failEmptyExit, same flag names). Property IDs normalized so 123456789 and properties/123456789 both work.

Tests

16 integration tests covering JSON + text output for all 4 subcommands, --all pagination, --fail-empty, input validation before API calls, and service init failures.

go test ./...  # full suite passes
