docs: remove expired and contradictory blocks from CLAUDE.md (R-229)

Surgical corrections only; the file is deliberately NOT restructured (deferred).

Deleted the expired TEMPORARY block. It read "felhom-pve is at a remote site
(until ~2026-08-02) ... Delete this block on return" and was still being read as
current fact on 2026-08-06, four days past its own deadline, while
felhom-controller/CLAUDE.md asserted the opposite. The location-independence fact
worth keeping (localapi binds 169.254.253.1:8443 on vmbr9 since the R-50 island
migration) moved to an HTML comment.

Every component version literal is gone from effective text, including the
--version reading and the go.mod Go directive. Versions change several times a
day; ask the hub's /hosts + /configs or the box.

The drill-VM claim and the host addresses now point at
documentation/operations/nodes.md, which already stated both correctly. This
file's drill-VM claim was the correct one -- confirmed by qm list on demo-hp.

The R-115/R-188/R-186 release narratives moved to an HTML comment and to the
felhom-build-deploy skill; the directives stayed (never hand-roll the build; the
build -> tag -> publish -> push order; reproducible -trimpath -buildvcs=false).

The health-check block-I/O rule became .claude/rules/health-checks.md, scoped to
the five packages where health checks are written. It had been duplicated from
felhom.eu/CLAUDE.md with a note explaining that that file does not load in an
agent-only session -- correct reasoning, made obsolete by path-scoped rules.

agent_gates.py registers the shared instructions gate.

Docs only -- no Go, no version bump, nothing built or deployed.
