fix: repair responsive container contracts

[Foscat]

What changed

• make personality enhancements respond to the nearest inline-size container
• defer three- and four-track app-shell signatures until their local allocation reaches 64rem
• preserve safe two-track thresholds and existing medium-width rhythms
• give Docs a distinct wide two-column geometry while retaining Dashboard's three-column shell
• update authored CSS, generated distributions, package/version surfaces, changelog, documentation, and release contracts for 2.1.1
• add root-wide/local-container browser coverage at 47rem, 49rem, 63rem, and 65rem across every personality

Root cause

Personality queries were bound to the full ly-personality root, so narrow nested allocations activated wide shell tracks. Dashboard and Docs also shared their wide geometry, making the two recipes visually indistinguishable.

Compatibility

This is a behavioral patch. It removes no selectors, tokens, data hooks, or structural APIs, and preserves DOM and keyboard order.

Verification

• npm.cmd run release:verify
• Stylelint and static documentation contracts
• Chromium, Firefox, and WebKit rendered suites
• package audit with zero vulnerabilities
• npm pack and publish dry-runs
• exact package candidate exercised by Interface Systems Lab across seven viewport widths

Pull request overview

This PR delivers a 2.1.1 behavioral patch to ensure personality/container-query-driven responsive layouts react to the nearest inline-size container (fixing nested allocation breakpoints), while preserving established two-track thresholds and differentiating Docs vs Dashboard wide shells.

Changes:

• Re-scopes personality container queries from @container ly-personality … to unnamed @container (min-width: …) queries, and gates 3-/4-track app-shell signatures behind a safe 64rem local allocation.
• Updates the Docs recipe to a distinct wide (64rem) two-column navigation + stacked content shell (Dashboard remains three-column).
• Bumps release surface to 2.1.1 (package versions, docs, workflows, changelog) and extends static + Playwright smoke contracts for the new responsive behavior.
