Add indexed pathfinding algorithms to the WASM pathfinding demo

[Zacaria]

Summary

• add pathfinding-indexed to the Rust engine and expose indexed BFS, DFS, Dijkstra, and A* through the WASM API
• update the web app to group classic vs indexed algorithms in the selector and surface the new options in the UI
• add frontend tests and test setup for the algorithm catalog and selector behavior
• refresh docs and project config to cover the new indexed-pathfinding workflow

Testing

• Not run (not requested)

Likely Future Issues (2)

Severity	Signal	Why it may show up
MEDIUM	Runtime config changes may ship without example or template updates	3 runtime config paths changed; 0 example or template config files changed
MEDIUM	User-facing UI changes may ship without browser coverage	1 user-facing UI paths changed; 0 browser or e2e coverage files changed

• Runtime config changes may ship without example or template updates: The PR changes runtime config or deployment settings but does not update any obvious example env file or config template.
• User-facing UI changes may ship without browser coverage: The PR changes components, pages, or other user-facing UI files without touching any obvious browser or end-to-end coverage.

Suggested Follow-up Work (2)

Type	Suggested title	Targets
PR	chore: sync config templates for .codex/config.toml + openspec/config.yaml	.codex/config.toml, openspec/config.yaml
PR	test: add browser coverage for web/src/components/ui/button.tsx	web/src/components/ui/button.tsx

• chore: sync config templates for .codex/config.toml + openspec/config.yaml: Backfill example env files or config templates before a fresh setup drifts from the shipped runtime surface.
• test: add browser coverage for web/src/components/ui/button.tsx: Backfill browser coverage before another user-facing UI change lands on the touched surface.

chore: sync config templates for .codex/config.toml + openspec/config.yaml

## Summary
- Update the example env files, sample configs, or deployment templates that should mirror the changed runtime configuration surface.

## Why
- Backfill example env files or config templates before a fresh setup drifts from the shipped runtime surface.

## Touched paths
- `.codex/config.toml`
- `openspec/config.yaml`

## Validation
- Update the repo example env file or config template that should reflect the new runtime settings.
- Run the setup, boot, or deployment validation flow that depends on the changed config surface.

test: add browser coverage for web/src/components/ui/button.tsx

## Summary
- Add browser or end-to-end coverage for the recently changed user-facing surface.

## Why
- Backfill browser coverage before another user-facing UI change lands on the touched surface.

## Touched paths
- `web/src/components/ui/button.tsx`

## Validation
- Add or extend browser / e2e coverage for the changed component, page, or flow.
- Exercise the visible user journey that depends on the touched UI surface.
