docs(spec): presets record themselves in exdata.meta; job-labels backlog item

- no preset field on the server: the client puts preset name + hash into
  the job's exdata JSON under 'meta', passed through uninterpreted; the
  worker skips 'meta' silently; 'preset report' filters jobs client-side
- drop the local submission log idea
- job-labels: independent backlog item (general server-side labels)
- bug-1970: note the dropped REST 'tags' field

 - [ ] project-delegated-membership — NEW 2026-10-10 (from project-config requirements, user decision: future). Project managers edit their project's (and subtree's) members at runtime without an admin config push; needs a durable store that coexists with `xceadmin` config pushes (e.g. a separate delegated member list) and audit. Dependencies: project-config, rbac-persistence.
 - [ ] job-modify — NEW 2026-10-12 (from application-profile discussion, user decision; backlog, no brief yet). Modify a pending job (LSF `bmod`): apiserver action (today `"modify"` is commented out, `controllers/jobs.go:2446`; `JOB_MODIFY` only an enum), controller opcode, WAL fact with snapshot field-completeness, scheduler re-merge, xcecli. First attributes: `--app` (owner with `app:use` on the new profile; admins in bulk, e.g. `--app-from <old>`), `-R`, `-n`, queue; later begin/end time (`job-time-window`), dependencies. Dependencies: application-profile, job-config-merge.
 - [ ] config-history-audit — NEW 2026-10-12 (from application-profile discussion, user decision: needed, roadmap). Keep past cluster-config versions (including `applications.yaml` profiles) with who changed what and when: `xceadmin config history` / `diff`, look up a profile by its content hash (the application-profile hash recorded on dispatch records), audit trail of live upgrades. Per-job display of the values a run used is already covered by the application-profile dispatch record; this adds admin history and audit. Covers the whole cluster config, not only profiles (the controller already tracks `configVersion`/`configChecksum`). Dependencies: application-profile, admin-config-tool.
+- [ ] job-labels — NEW 2026-10-12 (from application-profile discussion; backlog, no brief yet). General Kubernetes-style job labels: `--label key=value` (repeatable, limited charset and size), an additive submit-data field through WAL and snapshot (field completeness), server-side filtering (`jobs list -l k=v`) and summaries grouped by label (runtime, peak memory, efficiency); metadata only, never used for placement. Reuses or replaces the REST `tags` field that is silently dropped today (bug-1970). Not needed for presets (those use `exdata.meta`); candidates: team-wide comparison, services labelling replicas. Dependencies: none.
 - [ ] job-requeue — NEW 2026-10-12 (from application-profile discussion, user decision; backlog, no brief yet). Automatic requeue on given exit values (LSF `REQUEUE_EXIT_VALUES`) and success exit values (`SUCCESS_EXIT_VALUES`), with a requeue loop limit; wires the commented-out `requeue` job action (`apiserver/controllers/jobs.go`) and the REST `requeue_error_values` / `rerunable` options that are silently dropped today (bug-1970). Adds the matching application-profile attributes (a profile attribute ships with its job feature). Later, same principle: checkpoint settings and warning-before-kill each get their own spec. Dependencies: application-profile.
-- [ ] xcecli-presets — NEW 2026-10-12 (from application-profile discussion, user decisions). Client-side presets replace convenience defaults in profiles: a preset is a set of job options (`--app`, `--queue`, `-R`, `-n`, env, limits) expanded by the client, a flag replacing the preset's value for that option; one file per preset (`~/.config/xce/presets/<ns>/<name>.yaml`, same layout in the apiserver's presets dir), env capture by name (`pass:`; `XCE_*` and secret-looking names excluded); the apiserver only shares admin-deployed presets read-only (`GET /xce/v1/presets[/{ns}/{name}]`, files in `<TopDir>/config/presets/` or `presets.dir`, re-read on change; not in ClusterConfig), and `preset pull` copies one locally so server-side removal never affects users; on a name collision pull refuses unless it is an update of the same server preset (`--as` / `--force` with `.bak`); submit uses local presets only (`preset diff`, `pull --force` user-initiated); user-to-user sharing by `preset export`/`import`; presets carry no privilege and are not a configuration level; optional preset-name job label; the portal does the same expansion. Brief: `.kiro/specs/xcecli-presets/brief.md`. Dependencies: application-profile.

 - [ ] profile-usage-insight — NEW 2026-10-12 (from application-profile discussion, backlog; no brief yet). Per-profile report over recent jobs comparing the profile's defaults with actual use (requested vs. peak memory, CPU efficiency, OOM kills, pend time, runtime by variant) and suggesting better values for site presets (or a profile essential), e.g. "preset openfoam rusage mem 4000, p95 peak 1600 → suggest 2000" (Kubernetes VPA recommender precedent). **Advisory only** (user decision): the admin applies changes to site presets or `applications.yaml`; nothing tunes itself. Optional user hint ("used 1.4G of 4G requested"). Dependencies: application-profile, run usage in job records.
 - [ ] lsf-config-migration — NEW 2026-10-09 (user idea, backlog; no brief yet). A tool (likely an `xceadmin` subcommand) that converts LSF configuration (`lsb.queues`, `lsb.applications`, `lsb.resources` Limit sections, `lsb.users`/`lsb.hosts` groups, `lsb.params` defaults, project settings) into XCE `configs/*.yaml`, with a report of what does not map: queue `RES_REQ` (XCE queues are policy only; move into a profile or drop), LSF's full per-section merge rules vs XCE's simplified ones, compound/alternative resreqs, unsupported parameters. Dependencies: job-config-merge, application-profile, project-config, parjob-placement (span), admin-config-tool. Promote via `/kiro-discovery` when those land.
