feat(conscience): Aster reset commands, subagent thread chunking, conscience wiring

[IN TESTING — production on ani@wiuf.net, treat as experimental]

bot.ts — !reset aster cycles only Aster's conversation (leaves Ani's alone),
patches the systemd service file in place so restarts also use the new conv ID.
Full !reset now co-cycles Aster's conversation alongside Ani's so failure
notifications target the active context. Both commands write through to
lettabot-agent.json and daemon-reload immediately.

bot.ts — subagent thread results are now chunked at 16KB before posting to
Matrix threads. Previously truncated at 800 chars, cutting results mid-sentence.

store.ts / letta-api.ts — createConversationForAgent exposed for use by reset
commands. Store gains setAgentField for targeted JSON updates without clobbering.

config/types.ts, channels/factory.ts — conscience env var plumbing (CONSCIENCE_AGENT_ID,
CONSCIENCE_CONVERSATION_ID) wired through the config surface.

memfs-server.py — git sidecar for local memfs serving (port 8285). Serves bare
repos from ~/.letta/memfs/repository/ over HTTP. Required by letta-code memfs
in self-hosted mode.
