docs(conductor): clarify runtime support boundary

[Steel-tech]

README-only follow-up to #8. Clarifies the supported 0.7.5 release, unsupported 0.8.2 server, and isolated 0.9.3 development candidate. Verification: npm run check:docs passed; git diff --check passed. No release pin or runtime changes.

Summary by CodeRabbit

• Documentation
  • Clarified supported Herdr versions and compatibility requirements, including the need for a matching, healthy client and server.
  • Clarified that Herdr 0.8.2 is unsupported with the 0.7.5 CLI, and that the 0.9.3 candidate is limited to isolated synthetic testing—not production support or release certification.

📝 Walkthrough

Walkthrough

The README clarifies the client and server requirements for the pinned Herdr 0.7.5 release, marks 0.8.2 unsupported, and limits the 0.9.3 candidate to an isolated synthetic smoke.

Changes

Herdr support contract

Layer / File(s)	Summary
Version and health requirements README.md	The README requires a matching, healthy client and server for the pinned 0.7.5 release. It marks 0.8.2 unsupported, even with a 0.7.5 CLI, and limits the 0.9.3 development candidate to a synthetic smoke.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Change: Other

Merge Risk: 🔵 Low · up to 76cb8

The smoke description may leave readers unsure whether seven refers to invocations or action types. Clarifying that it covers seven action types across eleven invocations would make the documented validation scope precise; this does not affect runtime behavior.

Architecture Summary

Architecture risk: 🔵 Low · up to 76cb8

The change affects 1 system.

• observed — README.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

• observed — Modified behavior in README.md: The pinned requirements now explicitly require selecting a matching, healthy Herdr client and running server, noting that checking only the client version is insufficient.
• observed — Modified behavior in README.md: The contract table now distinguishes the pinned 0.7.5 release, explicitly marks 0.8.2 unsupported even when the selected CLI is 0.7.5, and states that 0.9.3 is a development candidate only when its client API shapes and running server identity are compatible and healthy.
• observed — Modified behavior in README.md: The 0.9.3 candidate is explicitly limited to the isolated synthetic seven-action smoke; the text reiterates that it is not a support promotion, release certification, production installation, or reason to change an existing 0.7.5 deployment.

Full details: Description check

Explanation

The description states the scope, key support clarifications, verification results, and absence of runtime changes. It does not follow the required template and omits the Scope, Contract and claim review, and Residual risks sections.

Resolution

Add the required template sections. State the change type, exact runtime behavior boundary, and destructive surfaces. Record applicable evidence checks and exact commands with results. Confirm contract and claim alignment, canonical documentation impact, evidence limits, and vendoring impact. Document residual risks or state that none apply.
