fix(reader): harden the reader against malformed/short-read input (never panic)

Honor the crate's "return an error, never panic" contract on adversarial or
truncated input reaching the browser-facing path:

- facet.rs: bounds- and overflow-check FacetIndex::open — checked size
  arithmetic (usize overflow on wasm32), validate name/category ranges before
  slicing, derive posting-region bounds with checked math
- wasm.rs: WasmFetch::read enforces the exact-length RangeFetch contract
  (rejects an origin that ignores Range) and guards offset+len overflow
- records.rs: RecordStore::get errors on a corrupt end<start offset pair
  instead of silently returning a zero-length record
- index.rs: replace the search() debug_assert (debug-build panic on a
  malformed tail) with a filter; saturating_add for untrusted tail offsets;
  add IndexError::Malformed
- tests: malformed-RRSF header and corrupt record-offset-pair cases
