ci(seedgo-audit): install memory extra so pyright resolves chromadb/numpy (DPLAN-0195)

Final straggler: memory scored 98% (diagnostics 55% = 9 pyright errors) in CI
while 100% locally. Proven cause: the diagnostics standard runs pyright over
every branch; memory's handlers import chromadb/numpy at module level. These
are declared in the 'memory' optional-dependencies group, NOT 'dev' — and the
audit job installed only '.[dev]', so pyright flagged them unresolved
(reportMissingImports=error) → 9 false errors. My local .venv happens to have
chromadb, which is why local audits read 100%.

Fix: audit job installs '.[dev,memory]'. pyright now resolves memory's real,
declared deps and the standard measures actual type-correctness (and matches a
local audit). api imports openai (llm extra) but guards it lazily, so it stays
100% without that extra — only memory needed this.

12/13 were already green after the readme check-ignore fix; this clears the
13th.
