Add bounded component-property inspection

[bjdodson-openai]

Description

Adds bounded read-only component-property inspection for exact web targets.

• Reads only own enumerable data descriptors and never invokes getters.
• Shares a 64 KiB emitted-value budget with bounded depth, keys, strings, and entries.
• Fails closed on hostile or revoked Proxies while preserving the hierarchy fallback.

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

• Incremental branch: Focused registry/panel/server 149/149 and full CLI 398/398 passed; web-renderer Bazel and query passed, with the broad suite matching its exact baseline.
• Assembled debugger stack: npm test passed 436/436; the CLI production build passed.
• Focused //src/valdi_modules/src/valdi/web_renderer:test passed.
• bazel query //... passed.
• The broad Valdi suite reproduced the established 12 unrelated failures; all new debugger specs passed.

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 component-property inspection. The bounds and fail-closed handling of hostile/revoked Proxies look solid. One low-severity performance note:

• 🟢 Low — captureObject in DebuggerValueSnapshot.ts only counts enumerable descriptors against the entry/byte caps; non-enumerable own keys are skipped (continue) without consuming budget or incrementing the entry count. A hostile object/Proxy with millions of non-enumerable own keys therefore forces one getOwnPropertyDescriptor (trap) call per key, with work bounded only by total own-key count rather than the 50-entry / 64 KiB caps → CPU stall on the snapshot path. Suggested fix: count every own key inspected against a hard iteration cap (or decrement the entry budget for skipped non-enumerable keys too) so traversal cost is bounded by the caps, not by the object's key count.

Note for the squash: please carry this feedback into the squashed PR that contains component-property 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Superseded by #180, which consolidates this patch into the reviewed debugger capabilities landing unit.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.
