chore(deps): update Azure commitments module

[cristim]

Why

The MCP server still resolves the older Azure commitments module. This PR changes only the direct Azure module version and Go-generated checksums so the registered Azure compute purchase tool can use the reviewed reservation cost semantics. AWS, GCP and the effective shared pkg module remain at their prior selected versions.

Evidence

• Published Azure module v0.0.0-20261004143708-56555e1be095 was authenticated through Go's public module proxy and checksum database.
• A scratch overlay exercised the registered MCP Azure compute tool through in-memory MCP transport, a concrete Azure client, a fake credential and strict synthetic HTTP. The actual handler supplies a zero commitment estimate, not an arbitrary nonzero input. With the old module, monthly was a nondiscriminating positive control; upfront failed two intended omission assertions because both first purchase and matching-order re-drive returned cost: 0. With the new module, monthly and upfront both passed: monthly response retained cost: 0, while upfront omitted cost on both attempts. The fixture checked the purchase request, stable idempotency token, response and audit records.
• Five selected existing mock-backed tests produced eight passing test leaves under -race -short. Offline module-graph inspection selected the intended Azure version and unchanged AWS, GCP and shared pkg versions. The MCP command built to a scratch output. Go-generated checksum updates left go mod tidy -diff clean.
• Ordinary commit hooks passed, including tidy, file checks, git-secrets and Trivy. Nonmatching hooks were skipped normally.
• An independent gpt-6-astra review of exact commit 2cdce51c19ac05ef7a142141421a4dc9ea61bc07 found no actionable issue in the complete manifest diff or affected old/new Azure source. The reviewer independently reran the registered CallTool through the concrete Azure client: monthly and upfront passed, including matching-order retries. Its retained local run log is /tmp/claude/go76-mcp-azure-astra-committed-treatment-v1.log (SHA256 35319fcc8ca09ddaf909ca9838e2b2824acc08c1fd3f45d408c9d5b9b7cebe35).

CI has not been observed for this branch yet. These tests use synthetic transports and do not establish live Azure catalog availability, a real reservation purchase or end-user acceptance.

Dependency and scope

This PR depends on the still-open Azure pricing stack PR #187 and its ancestors. Do not merge it ahead of that stack or treat fixture-backed evidence as the remaining real-scenario acceptance. This is one MCP dependency pin, not the full fix for cloud-commitments-go #76 or #132; both remain open. Refs LeanerCloud/cloud-commitments-go#76 and LeanerCloud/cloud-commitments-go#132.

Merge Risk: 🔵 Low · up to 2cdce

This change depends on the open provider stack, so merging it now would violate the stated order. Hold it until #185–#187 merge, then recheck their status.

Exact head 2cdce51: pre-commit and CI - Build & Test both completed successfully; all nine build/test workflow jobs succeeded. The upstream Azure stack and live reservation acceptance remain open gates. No merge is implied.
