docs(product): define live pilot entry criteria

[ootakazuhiko]

Summary

• Add docs/product/LIVE-PILOT-ENTRY-CRITERIA.md as the SSOT for live/external pilot entry decisions before fixture-backed Evidence Sprint material can support live claims.
• Define entry states, minimum consent/data-handling/retention criteria, required evidence artifacts, required measurement fields, and supported/unsupported claim boundaries.
• Link the criteria from README/docs navigation, Evidence Sprint measurement and pilot reports, external pilot onboarding/runbook/report, release assets, and the launch kit.

Acceptance

• Live-pilot entry criteria are documented with explicit supported/unsupported claim boundaries.
• Required evidence artifacts and measurement fields are listed.
• External repository, data-retention, and consent assumptions are explicit.
• Fixture-backed Web API/event-driven pilots and the ACP-097 report remain marked report-only/dry-run until the criteria are satisfied.

Verification

• pnpm -s run check:doc-consistency
• pnpm -s run docs:lint (0 warnings after README wording adjustment)
• pnpm install --frozen-lockfile (local worktree dependency install before schema/type verification)
• node scripts/ci/validate-json.mjs
• pnpm -s run check:schemas
• pnpm -s run types:check
• pnpm -s run verify:lite (passed; existing lint findings remain warn-only under baseline)
• git diff --check && git diff --cached --check

Context Pack conflict

• none. This is a product documentation and navigation update. spec/context-pack/boundary-map.json has no direct docs/product, docs/guides, README.md, or docs/README.md slice mapping affected by this change, and no Context Pack schema or boundary semantics are modified.

Rollback

• Revert this PR to remove the live-pilot entry criteria document and restore the prior documentation links. No runtime, schema, CI policy, or enforcement behavior is changed.

Closes #3586

Pull request overview

This PR introduces a new product SSOT document that defines live/external pilot entry criteria (consent, data handling/retention, required artifacts, required measurement fields, and supported/unsupported claim boundaries) and wires it into the existing Evidence Sprint and pilot documentation so fixture-backed/dry-run materials remain explicitly report-only until the criteria are met.

Changes:

• Add docs/product/LIVE-PILOT-ENTRY-CRITERIA.md as the SSOT for promoting fixture-backed/dry-run pilot material to live external collection and publishable claims.
• Update README/docs navigation and multiple Evidence Sprint / pilot docs to reference the entry criteria as a prerequisite for any live external claims.
• Align launch kit and measurement protocol wording with the new gate (explicitly separating report-only readiness from claim-ready evidence).
