release: v1.2.2 — pi 0.80.2 + mempalace 3.5.0, drop anyOf workaround

- Bump mempalace pin 3.4.0 -> 3.5.0: 3.5.0 carries the upstream fix for the
  top-level-anyOf diary_write schema (issue #1728 / PR #1717, merged
  2026-06-14). Verified against the published 3.5.0 wheel that mcp_server.py
  now advertises 'required: [agent_name]' with no root-level anyOf.
- Remove the Dockerfile.base perl workaround that stripped the anyOf from the
  installed mcp_server.py — obsolete now the fix is upstream.
- pi auto-resolves to npm latest (0.79.10 -> 0.80.2) at build.
- CHANGELOG v1.2.2.

-# ── workaround: strip top-level anyOf from mempalace_diary_write schema ──
-# Mempalace 3.3.x/3.4.0 advertise diary_write's input_schema with a
-# top-level `anyOf: [{required:[entry]}, {required:[content]}]` to express
-# "either entry or content must be supplied". Anthropic's tools API rejects
-# top-level anyOf/oneOf/allOf, so pi/Claude fail at session start with
-# `tools.<n>.custom.input_schema: input_schema does not support oneOf,
-# allOf, or anyOf at the top level`.
-#
-# Patch the advertised schema to require ["agent_name", "entry"] and remove
-# the anyOf block. The handler keeps accepting `content` server-side as a
-# kwarg alias so existing callers still work.
-#
-# Idempotent and self-deactivating: once upstream releases the fix the
-# regex no longer matches (and the WARN below fires) — that's the signal
-# to delete this RUN.
