The one-shot request/response complement to the never-returning
`tail --events` stream — what an agent poll loop wants. The IPC server now
keeps a single global, arrival-ordered event log keyed by a monotonic
cursor (alongside the per-subsystem replay ring), bounded by eventLogDepth
with drop-oldest back-pressure (D-85: producer never blocks).
`clide events [--since <cursor>] [--filter X]` returns events after the
cursor, a high-water `cursor` to poll from next, and `gap: true` (+
oldestCursor) when the requested cursor predates the retained window so a
caller detects loss instead of silently missing dropped events. Repeated
polls neither drop nor duplicate. No on-disk persistence.
`events` is handled in the IPC server like `tail` (not the dispatcher);
added to the argv umbrella set. bindingWhen/CommandContribution untouched.

Parity guarantees a verb exists for every UI action, but a verb is
unreachable if nothing advertises it. Add `clide capabilities` — it
reflects the live dispatcher registry to JSON (subsystem, verb, arg
schema) so the surface is discoverable and can't drift from what
dispatches. A thin /clide skill points Claude at it rather than
hard-coding a verb list, so new panels become reachable the moment
they register.

Second slice of T-99. Pure Dart function that takes the argv tail of
a `clide ...` invocation and returns either an IpcRequest ready to
dispatch or an ArgvError carrying a pre-built userError response.
The grammar — `SUBSYSTEM VERB [pos...] [--flag value] [--flag=val]
[-- passthrough...]` plus the umbrella commands `status`, `tail`,
`version`, `ping` — sits here so the C client (T-126) is a dumb
pipe: it sends argv as JSON and the server runs the translator
before dispatch.
Wire envelope: cmd is `subsystem.verb` (or just `subsystem` for
umbrella commands). Args is a generic envelope —
`positional: [...]`, `flags: {...}`, `passthrough: [...]` — none
required, all omitted when empty so the dispatch surface stays
minimal. Per-command typed schemas land later as each CLI verb
gets wired end-to-end.
