docs(pi): unify split package trees; move live OMP pages to core

Two directories documented one concept (pi npm packages): top-level
packages/ (browser-use, permission-system) and pi/packages/ (peon,
web-access, subagents). Merged into pi/packages/ — one row per package
in a single index, detail pages kept as archive records. The root
index's 'OMP packages and skills' section was doubly wrong (packages/
was pi, not OMP); it becomes a Skills tooling section pointing at the
consolidated /skills/ tree.

Moved the two LIVE omp pages out of the retired-harness banner:
pi/statusline.md -> core/statusline.md, pi/subagent-limits.md ->
core/subagent-limits.md (both document omp behavior against
agent/config.yml + the installed bundle; pi/index.md itself admitted
the mis-shelf). Retargeted every inbound link (core/index, system/
dankserver, log x2, pi/index, settings x2, moved files' own xrefs).

 ## 2026-10-18 — Status line docs truth audit (full-source re-verification)
 
-Exhaustive claim-by-claim re-audit of [OMP Status Line Customization](/pi/statusline.md) against the minified `dist/cli.js` bundle plus a live screenshot matrix (band × {off, percentage, embedded}, claude × off). Page carries an **Audit log** section; four first-pass claims were false and are corrected (see there): claude's rule is *not* the context meter (meter is `box`/`band` only; the "red rule" was the session-accent filler), the "Tern-only" composer-bar claim was bogus (the readout is `composer.tokenRate`, default off), `segmentOptions` are **not** gated to `preset: custom` (only the segment arrays are), and the `mode` segment's states are Plan/Prewalk/Goal/Vibe/Loop (no yolo). Page expanded with: the 7-preset defaults table, per-shape `statusAttachment`/`bottomBar` model (8 built-ins + plugin shape registry), `contextLine` per-value behavior, the 27-segment catalog with triggers/options, `segmentOptions` schema, and the full `statusLine.*`/`composer.*` knob registry. The bundle's own "(box composer only)" knob description for `contextLine` is upstream-wrong — band honors it.

 ## 2026-10-18 — Status line rebuilt on custom segments; frank-archon display name slimmed
 
-Interactive tune-up of the omp status bar (grilling session, live loop: config edit → watcher repaint → niri screenshot verify). New knowledge page: [OMP Status Line Customization](/pi/statusline.md).

 * **Mechanics discovered:** `leftSegments`/`rightSegments` are inert unless `preset: custom` (fleet was on `nerd` with dead arrays; `segmentOptions` *do* merge under named presets); `composer.shape` routes them — `band` merges both arrays into one row above the editor (title rides the working row), `claude` splits them into top chip + bottom strip. The context meter exists **only in `box`/`band`** — `contextLine`: `off` plain rule, `embedded` hoists the context segment into the labeled inline meter (`60% ——— × 200K`), `percentage`/`annotated` paint an unlabeled proportional rule meter (all four live-verified); every other shape's rule is a constant session-accent filler. Working row (session title + tok/s readout gated by `composer.tokenRate`, default off) is composer chrome — model/thinking can never join it. Eight composer shapes ship in the bundle; plugins can register more.
 * **Final bar (`band`, after a `claude` sojourn):** left = `session_name · vim · mode · hostname · path · git(no branch text) · pr`; right cluster in array order = `model · cost · time_spent` (`context_pct` hoists out of the run to paint the labeled inline meter `60% ——— × 200K` as a flexible spacer between the groups). Cut: tok/s duplicate, clock, cache trio, `context_total`, `subagents`, `session` hash, and `token_in`/`token_out` (cumulative totals live in `/session`). `path`: logical `project/worktree` label (`stripWorkPrefix: true`, kept after a live `false` trial of the full cwd); branch text dropped (worktree branches are autogenerated), dirty badges kept.
