fix(#3245): resolve broken intra-doc links in hive-c0re

Remove or fix broken documentation links that accumulate silently:
- container_view.rs: HiveEnv reference
- forge/mod.rs: READY_TIMEOUT and webhook handler links
- workers/knowledge.rs: webhook handler link
- job_queue/model.rs: Claim::deps and WireNode::data references
- stats/hive_stats.rs: read_skill_breakdown reference
- stores/audit_log.rs: global() reference
- workers/agent_sockets.rs: ambiguous agent_sockets::write reference
- coordinator.rs: systemd.services.<harness> formatting
- resource_limits.rs: ambiguous write/read references

Some broken links were to deleted functions/types; these are replaced
with prose descriptions. Others referenced items outside this crate or
were private; these are replaced with plain text references or qualified
paths as appropriate.

Fixes: #3245
