Add bounded runtime-state inspection

[bjdodson-openai]

Description

Adds bounded runtime-state capture and browsing as the final core debugger-stack capability.

• Captures exact component-instance state through own data descriptors under hierarchy-wide byte, projection, and reflection budgets.
• Strictly parses escaped web JSON while keeping structurally untrusted native state escaped and raw-only.
• Uses collision-free row identities, fail-closed Inspect targeting, and focus-safe refresh deferral.

Type of Change

• Bug fix (non-breaking change that fixes an issue)
• Documentation improvement
• Performance optimization
• Test improvement
• Other (new debugger capability)

Testing

• Tests pass locally (bazel test //...)
• Added/updated tests for changes (if applicable)
• Tested on multiple platforms (iOS/Android/Web/macOS as applicable)
• Manual testing performed (describe below)

Testing Details

• Runtime State passed 21/21; integrated DevTools passed 66/66; combined coverage passed 87/87.
• Full CLI passed 436/436 and the production build passed.
• Focused //src/valdi_modules/src/valdi/web_renderer:test passed after 11,519 actions.
• bazel query //... passed.
• The broad Valdi suite reproduced the established 12 unrelated failures; all runtime-state and property-edit specs passed.
• Two final independent audits were clean at frozen patch fingerprint 9607de6e04b2d332e1573ae450488f7f1bfa5274633e4a432e00c89e96618fd0.

Checklist

• Code follows project style guidelines
• Documentation updated (if needed)
• No breaking changes (or documented in description)
• Commit messages follow conventional format
• No secrets, API keys, or internal URLs included

Review of bounded runtime-state inspection. Capture budgets and read-only semantics look consistent with the property-inspection path. One low-severity performance note:

• 🟢 Low — renderRuntimeStateSection calls parseRuntimeState(record.source) for every filtered component (including collapsed rows) on every stateFilter input keystroke. With up to the hierarchy cap of stateful components each holding up to ~64 KiB of captured state, each keystroke re-parses all of them → UI jank on large hierarchies. Suggested fix: memoize the parsed result per record (keyed by source identity/revision) and/or parse lazily only for expanded/visible rows, so filtering doesn't re-parse the whole tree on each keystroke.

Note for the squash: please carry this feedback into the squashed PR that contains runtime-state inspection.

Superseded by #180, which consolidates this patch into the reviewed debugger capabilities landing unit. The replacement carries forward the feedback and fixes discussed here. Closing this draft to reduce the active stack; this PR and its discussion remain the historical review record.
