Ships the lineage layer that ties agents back to their team template
and wires the MCP skills server to actually merge template default
skills with per-agent overrides.
Migration 0050 adds `agent_template_link` (agent_id PK, template_id,
template_version, role_slot, seeded_at, created_at + indexes for
template/role lookups). Populated at agent-materialization time by
Slice 4's mission-launch orchestrator; read here by the skills MCP
server and by future level-up (Slice 8.5).
New Rust surface:
- cm_db::repo::agent_template_link (upsert / get / mark_seeded /
agents_for_template — the last is what level-up's "prompt upgrade
on template N+1" query needs)
- cm_api::brain_seed::ingest(claw_id, seed_md, identity_prompt)
opens cm_brain::ClawBrain on spawn_blocking, sets system_prompt
on first touch, writes seed as agent_md, commits. Idempotent —
skips when agent_md already populated.
- cm_api::mcp_skills::mcp_skills tools/call now resolves the caller
agent's template + role via agent_template_link and merges
template default skills with per-agent overrides (was overrides-
only in Slice 3.5b).
- cm_api::team_template_loader now binds template_role_skills after
upserting each template — looks up each declared skill by name,
attaches with pin_in_context=true for foundation skills and the
first two role skills. Missing skills log + skip.
- Boot ordering: skills load BEFORE team templates so the binding
lookup resolves.
Follow-up (Slice 4): mission-launch orchestrator calls brain_seed::ingest
+ agent_template_link::upsert when minting a team from a template.
Until that lands, the link is populated only by manual writes; the
MCP merge is silent-no-op for agents without a link (falls through
to overrides-only), which matches the pre-3.5d behavior.

-- When a team is minted from a template we record which template +

-- - diff the agent's brain against the seeded brain_seed

-- - route "add skill to my team's template" proposals to the right

-- template row + version

|
-- - offer template-upgrade prompts when the template ships a new
|
|
-- version and the agent is still on an older one

-- Also: adds a `first_seeded_at` timestamp on agents so the brain-seed
