feat: implemented ps shell builtin with sorting and formatting options

- Added the `ps` shell builtin with BSD and procps selection forms, custom formatting, and sorting capabilities.
- Implemented the `sanitize_process_command` helper to clean process command names and arguments.
- Updated the bash prompt template and package changelogs to document the new builtin.

 ### Added
 
+- Added optional `timeoutMs` to `discovery` configuration in provider options (`models.yml` / `models.json`) to configure custom HTTP probe timeouts for llama.cpp, Ollama, and OpenAI-compatible discovery endpoints ([#6952](https://github.com/can1357/oh-my-pi/issues/6952)).
+- Added a cross-platform, in-process `ps` shell builtin with BSD/procps selection forms, custom output columns, sorting, process metrics, and header suppression.
 - Added a `relay` browser mode that drives the user's own Chrome tabs through a local CDP relay plus the OMP Browser Relay extension: `omp browser-relay install` writes the bundled extension to disk, and `browser.relay` / `browser.relayUrl` (or per-call `app.relay`) route the browser tool through it. The relay server auto-starts under a profile-independent global daemon broker when the browser tool needs it; every relay consumer holds a broker lease, so the fixed-port singleton stops only after its last consumer across all projects exits. `omp browser-relay` remains available for `--token`/`--no-group`/custom ports, and a relay already serving the port is adopted. It multiplexes the supervisor and per-tab worker puppeteer connections over the single `chrome.debugger` attachment Chrome allows per tab, and gathers only the tabs the agent actively drives into a per-window "omp" tab group (released when the last client lets go of the tab, dissolved on disconnect, never re-grouping tabs the user pulls out).
 - Added a scriptable desktop session with persistent `desktop`/`Win`/`El` handles, window-targeted capture and input, native accessibility trees with `[ref=eN]` actions, clipboard access, streamed screenshots, and enforced read-only runs.
 - Added broker-shared language servers: one LSP server per (server, project) is now spawned by an `omp lsp mux` daemon under the per-project daemon broker (the same broker that owns the shared Chromium and `hub start` processes) and multiplexed to every omp instance in the project over a local socket — instances share the server's index, initialize result, diagnostics, and document state instead of each paying a private cold start. The mux reference-counts `didOpen`/`didClose`, remaps request ids and document versions per client, replays cached diagnostics/registrations/progress to late joiners, routes `workspace/applyEdit` to the most recently active instance, and intercepts per-session `shutdown`/`exit` so one instance leaving never kills the server for the rest; the broker still reaps everything when the last omp process in the project exits. Controlled by the new `lsp.shared` setting (default on); any broker/mux failure falls back to a private server spawn, and an external `lspmux` wrapper keeps precedence when configured.
