fix: support quoted structure names in structure command diagnostics (#456)

Quoted structure names in commands (e.g. `structure load
"mystructure:house" ~ ~ ~`) triggered false "missing structure" errors
because the diagnoser compared the raw token—including surrounding
quotes—against stored unquoted IDs.

## Changes

- **`diagnose_structure_implementation`** — call `Text.UnQuote()` on the
resolved ID string before all lookup checks, consistent with how other
diagnosers (tickingarea, fake-entity, mcfunction, etc.) handle quoted
tokens.
- **Structure diagnoser test** — add a case asserting that a quoted
token resolves cleanly when the unquoted ID exists in the pack.

```
# Before — false positive error
structure load "mystructure:house" ~ ~ ~
#              ^^^^^^^^^^^^^^^^^^^  → looked up as `"mystructure:house"`, not found

# After — no error
structure load "mystructure:house" ~ ~ ~
#                                  → stripped to `mystructure:house`, found ✓
```
