feat(cli): capture ios_package_manager in telemetry

[alexgerardojacinto]

Description

Adds ios_package_manager to the Capacitor CLI's telemetry payload so every command emitted from a project with an iOS platform reports the dependency manager in use (Cocoapods | bundler | SPM | unknown). Detection reuses the existing memoized config.ios.packageManager promise and is guarded so non-iOS projects or detection failures yield 'unknown' and never throw out of telemetryAction. The existing app_id continues to be sent unchanged and remains the dedup key — no new identifier, no paths, no bundle IDs.

Rationale / Problems Fixed

Need real-world data to prioritize SPM tooling work and plan CocoaPods deprecation; the CLI is the only signal source. Because cap sync runs many times per day, raw event counts would overstate adoption — emitting the new field alongside the existing app_id lets downstream consumers dedup per project. Dashboard and metrics-backend work to consume this signal is intentionally out of scope and will be tracked in a separate follow-up.

Tests or Reproductions

Unit tests in cli/test/telemetry.spec.ts cover the three behavioral branches of getIOSPackageManager:

• iOS platform dir missing → 'unknown'
• iOS present, packageManager resolves → returns the value
• iOS present, packageManager rejects → 'unknown'

Manually verified against four fixture apps with DEBUG=capacitor:telemetry npx cap sync <platform>:

Also, and more importantly, checked that the new ios_package_manager field is getting to our endpoint and then being sent to Snowflake.

Fixture	Setup	ios_package_manager
SPM app	CapApp-SPM/ (default iOS template)	'SPM'
CocoaPods app	Podfile, no Gemfile	'Cocoapods'
Bundler app	Podfile + Gemfile with gem 'cocoapods' + bundle on PATH	'bundler'
Android-only app	no iOS platform dir	'unknown'

Each fixture emits a distinct app_id, confirming the dedup key still works per project. AC coverage for sync, update, copy, build, run, open is automatic: the new field is added inside telemetryAction itself, so every wrapped command picks it up.

Notes / Comments

Includes a debug('metric payload: %O', data) line in telemetry.ts to make local inspection cheap (silent unless DEBUG=capacitor:telemetry is set). Happy to drop it before merge if reviewers prefer to keep the diff strictly scoped to the AC.
