feat: wavelength/connector enrichment schema + enricher robot
- sql/110: add wavelength_tx_nm, wavelength_rx_nm, connector_type,
data_completeness, enrichment_needed columns + trigger
- sql/111: IEEE/MSA standards wavelength lookup table (SFP→OSFP)
- sql/112: migrate existing wavelengths TEXT → integer columns
- robots/wavelength-enricher.ts: fills missing wavelengths from IEEE
lookup (deterministic) then product-name regex, runs every 4h
- scheduler: register enrich:wavelength job (4h schedule)
Fixes over-broad matching where 1G SFPs match 500+ competitors
due to missing wavelength discrimination.
