docs(plans): mark post-fix remainders as Done — all 18 fixes shipped, 4/4 evals pass

Status: In Progress → Done. All 18 fixes (A.1-A.3, B.1-B.6, C.1-C.2, D.1-D.2,
E.1-E.2, F.1-F.3) shipped in commits 337d577 + 3de359b + dd3076a, deployed
to oikos-nomos-1 (v0.5.3). The golden eval harness (cmd/nomos/eval/) passes
4/4 conversations, validating the structural gates + the SOUL.md
consolidation. Also fixed a pre-existing tool-call doubling bug found by
the eval harness.

Only remaining open item: the OIDC token-refresh fix (PM addition, web/src/
lib/{config,oidc,events}.ts) — implemented, not yet committed/deployed.
