Codified machine-readable 14-tag capability vocabulary and per-host concurrency budgets, created canonical fleet_host_tags.zsh engine, integrated tyrell host tags and tyrell fleet hosts subcommands into Tyrell CLI, deployed ~/.tyrell/host.json and ~/.agent-coordination/host-tags.env to all reachable hosts, and resolved ticket FEAT-20260905-20 on canonical hub.

Verification Evidence

fleet_host_tags.zsh verify passed rc=0 on rdmbair15m5 and rdmsm4x.
tyrell host tags output verified on rdmbair15m5: canary-tyrell canary-replicantdb build-arm64 laptop-interactive notes-publisher.
tyrell host tags --has canary-tyrell returned rc=0; --has nonexistent returned rc=1.
tyrell fleet hosts --tag linux-compute returned rdmpw3265m rdmpw3275m.
Dynamic probing verified: notes-publisher tag is dynamically evaluated and excluded in headless/non-Aqua environments.
