For article #45967: Rollout rings with Fleet labels.
Adds three drop-in label YAML files under docs/solutions/all/labels/:
rollout-rings.labels.yml — five cumulative dynamic labels (1%, 5%, 25%,
75%, 100%) for gradual software rollouts via labels_include_any. Each
ring is a superset of the previous.
rollout-waves.labels.yml — five disjoint dynamic labels covering the
same percentage breakpoints, for A/B experiments and per-wave reporting.
pinned-canaries.labels.yml — manual label for pinning specific hosts
(dev Macs, QA machines) into the first wave regardless of their natural
UUID shard.
All three use the same deterministic UUID-based shard expression
(positions 10 and 25, avoiding RFC 4122's fixed version/variant digits
at positions 15 and 20) so a host's ring assignment never changes across
reboots or agent reinstalls.
New folder docs/solutions/all/labels/ follows the existing pattern of
docs/solutions/all/policies/ and docs/solutions/all/queries/.
The companion article is in draft and will follow in a separate PR; it
references these files via
https://github.com/fleetdm/fleet/blob/main/docs/solutions/all/labels/...
URLs.

## Summary by CodeRabbit
## Release Notes
* **Documentation**
* Added comprehensive labeling solutions for managing staged rollouts:
manual pinned canaries for selecting priority hosts, cumulative rollout
rings covering multiple deployment phases (1%, 5%, 25%, 75%, 100%), and
partitioned rollout waves for balanced phased distribution strategies.
