Fix WebMCP repository-first workflow

[erinepshovel-code]

What changed

• Move repository selection to step 1 and agent-work/skill selection to step 2.
• Keep skill search and selection disabled until a repository establishes context.
• Invalidate the prior skill, automatic refresh request, and handoff when the repository changes.
• Restore URL state in repository-first order and present repository identity first in the handoff.
• Add focused source-contract and browser-path regression coverage.

Verification

• git diff --check
• node --check src/assets/js/webmcp.js
• node --check tests/site.spec.mjs
• node --test tests/webmcp.test.mjs — 7/7 passed

Usage

Open /webmcp/, choose the target repository, then choose how the agent should work, state the outcome, and press Send. Changing the repository requires choosing the skill again.

hmmm

The new browser-path test is committed for the repository's authoritative CI/browser gate; focused local checks pass.

Clear stale output when changing repositories

After a skill has been selected or a handoff has been sent, changing the repository clears selectedName and invalidates the tool but leaves [data-webmcp-output] displaying the previous repository, skill, or full handoff. The page can therefore show the new repository alongside an obsolete SELECTED REPOSITORY → SKILL or HUMAN → AGENT HANDOFF record; reset or replace that output as part of this invalidation.
