Replace the footer's placeholder usage with a real observation ledger
The footer showed invented percentages. It now shows what two harnesses actually report, or says it does not know. lumbridge-core gains an append-only per-profile UsageLedger and a projection that labels every derived value estimated, withholds a burn rate from a single sample, withholds a window fraction with no reported ceiling, withholds an exhaustion estimate that lands after the reset, and reports an expired window as rolled over rather than freezing its last percentage. A missing fact renders as missing, never as zero. (0012) lumbridge-harness is the impure side: processes, clocks, and untrusted wire text in, observations out. Three adapters: - Codex's account/rateLimits/read over the app-server's JSON-RPC stdio. The client cannot express a request outside a two-variant enum and answers every server-to-client request with -32601, so a harness asking Lumbridge for a credential is refused by construction. (0013) - Claude Code's session transcripts, as a byte-offset tail follower that reports nothing until the backlog is read to EOF — a partially-read backlog is indistinguishable from a burst of spend, and the first run against 20 MB reported forty-six billion tokens an hour. The parser models four counters, so the conversations in those files are not representable. (0014) - Claude Code's five-hour and seven-day subscription windows, via a bridge installed as its statusLine command. 0014 had claimed no such surface existed; it does, and the record is corrected in place rather than quietly edited. Lumbridge does not read the OAuth credential to call the account usage endpoint, which is what comparable tools do — AGENTS.md forbids it, and 0015 says so rather than leaving the gap unexplained. Also in here: a capability-check ordering fix in the workspace reducer, where the applied-request replay table was consulted before the capability check and so answered questions the caller had no right to ask; the GPUI spike wired to the live probes with per-harness gauges and provenance chips; and a launcher that matches its own window by PID, because GPUI sets WM_NAME but not _NET_WM_NAME and a title match never succeeded.
