No linked issue.

Update the host workload to 4.1054.200, the second-latest stable release reported by GitHub releases for Azure/azure-functions-host, and align worker payloads with that release's dependency manifests.

Payload	Previous	Updated
Host	4.1048.200	4.1054.200
Java	2.19.4	2.19.5
Node.js	3.13.0	3.16.0
Python	4.43.0	4.46.0
PowerShell 7.4	4.0.4759	4.0.5361
PowerShell 7.6	4.0.4778	4.0.5362

Keep central package pins synchronized and add release notes for each updated workload. Existing preview suffixes are preserved. Go remains unchanged because the host release does not include a Go worker.

Add Azure.Functions.Rpc.Server source mappings to the Azure Functions release and prerelease feeds. Without these mappings, restore selects 4.1054.250 from upstream instead of the matching 4.1054.200 dependency, causing package downgrade errors.

Additional information

Upstream release: https://github.com/Azure/azure-functions-host/releases/tag/v4.1054.200

User-visible change: installing these workload versions provides the updated host and worker payloads. No CLI command or option changes.

Validation:

• dotnet restore --verbosity quiet — passed.
• dotnet build --no-restore -c Release --verbosity quiet — passed with zero warnings or errors.
• dotnet test --no-build --no-restore -c Release --verbosity quiet — passed; 3,069 tests.
• git diff --check — passed.
• Verified worker pins against the upstream v4.1054.200 manifests.

No new tests were needed for this dependency-only update.

Worker versions are updated directly in this PR. The legacy release-preparation command is:
pwsh ./eng/scripts/validate-worker-versions.ps1 --Update -HostVersion 4.1054.200
That script is not present on this vnext branch and was not run.
