Adds the attribute keys the Apple and Android clients need to record
startup, network, auth, and playback behavior in diagnostics reports.
The four playback keys were already being emitted by the Apple client
but were never registered here, so they were silently dropped by this
collector and hard-rejected by the hosted one. Registering them makes
the canonical registry the superset it was always meant to be.
position_seconds is deliberately registered as position_ms (integer):
attrValueType has only string and integer, and a millisecond ordinal
avoids adding a float type for a single key. launch_type is a string
for the same reason, rather than a bool.
New keys:
playback: session_id, play_method, reason, position_ms
lifecycle: phase, duration_ms, outcome, reason, launch_type
network: outcome, error_code, attempt
Purely additive; no existing key changes type or is removed.
TestAttrRegistryStaysInSync keeps the Go map and the JSON in lockstep.
