ci(gitignore): ignore generated/* artefacts (Refs standards#93) (#45)

Apply the prepared .gitignore stanza from
hyperpolymath/standards#93 so that future
regenerated outputs from boj-server -mcp cartridges (k9iser, tlaiser,
wokelangiser, alloyiser) and hand-generated abi/* don't get accidentally
committed.

Existing tracked `generated/*` files are intentionally NOT removed:
that step waits on the http-capability-gateway tier-2 production
wiring (standards#91 Phase E / standards#100, ~8-12 wk). Until the
regen path is wired, consumers depend on the committed copies.

Refs hyperpolymath/standards#93.
