feat(go): port FIM/pkgdb/rootcheck integrity engines and add go-sidecar dashboard consumer

Browse source 
Adds sidecar-only, --state-dir-gated FIM, package-DB-anchor, and rootcheck
engines to the Go migration sidecar, wired into agent.Sweep/Initialize
behind the existing baseline lifecycle. Adds a read-only, schema-checked
Python dashboard consumer (go_sidecar_state_dir, /api/go-sidecar/*, Sidecar
tab) that never starts, stops, or mutates the Go sidecar's state.

Also fixes drift found while reconciling this work: enodia_sentinel/web.py
had reinvented local schema constants instead of using the canonical
enodia_sentinel/schemas.py catalog (now registers enodia.go.sidecar.v1
there and reuses ALERT_SNAPSHOT_V1/INCIDENT_V1); docs/RULES.md had drifted
from what `rules docs` actually generates for SIDs 100069-100078 (ruleops.py
was missing metadata for four SIDs and had stale drill text for four more),
now back in sync with a regression test pinning them together.

Updates CLAUDE.md, README.md, go-agent/README.md, and docs/{ROADMAP,
GO_PORT_HANDOFF,SURICATA_ASSIMILATION,THREAT_MODEL,OPERATIONS,SCHEMAS,
COMMAND_REFERENCE}.md to reflect the landed work.
