Pull request overview

This PR refreshes the azure-mgmt-alertprocessingrules management library after its migration to TypeSpec (API version 2021-08-08, beta release). It introduces a brand-new package under sdk/alertsmanagement/ that splits Alert Processing Rules CRUD operations into their own client, and wires the package into the service CI.

Changes:

• Adds the new azure-mgmt-alertprocessingrules package (client, config, models, operations, types) generated from TypeSpec, versioned 1.0.0b1.
• Adds packaging/config scaffolding (pyproject.toml, README, CHANGELOG, LICENSE, MANIFEST.in, dev_requirements, tsp-location, api/metadata files).
• Registers the new artifact in sdk/alertsmanagement/ci.yml.

File	Description
ci.yml	Adds azure-mgmt-alertprocessingrules artifact; format matches existing entry
_version.py	Sets VERSION = "1.0.0b1", consistent with CHANGELOG
CHANGELOG.md	Initial 1.0.0b1 (2026-07-09) entry; date matches current date
pyproject.toml	Preview flags correct: is_stable=false, Beta classifier, title=AlertProcessingRulesMgmtClient
_client.py (sync/aio)	Client signature order credential, subscription_id, base_url; name consistent with README/pyproject
README.md	Sample code matches client signature
tsp-location.yaml / _metadata.json	Spec source/commit references for regeneration
apiview-properties.json / api.md / api.metadata.yml	Generated API surface snapshots
MANIFEST.in / LICENSE / dev_requirements.txt	Standard packaging scaffolding
Generated source/samples/tests	Emitted by TypeSpec generator (excluded from detailed mgmt review)

All applicable mgmt review checklist items pass: version consistency, changelog date, stability flags, client __init__ parameter order, subscription_id present (so no_sub not required), and client-name consistency across _client.py, README.md, and pyproject title. I found no objective issues within the reviewable scope, so I have no line comments.
