Real-time code feedback for pi — LSP, linters, formatters, type-checking, structural analysis & booboo

# LSP server capability inventory

Advertised capabilities of every LSP server pi-lens supports, read from each
server's `initialize` handshake. Generated by `node scripts/server-capabilities.mjs
[--install]` (requires `npm run build:dist`). Servers whose toolchain/binary is
absent on the generating host are listed under *Unavailable* — run in a
provisioned environment (the nightly) to capture those rows.

_Last generated: 2026-07-14 on linux; 30 servers captured, 11 unavailable._

## Diagnostic mode + navigation/edit operations

Legend: ✓ advertised, · not. **mode** = document diagnostics (`pull` = `textDocument/diagnostic`, else push-only); **ws-pull** = advertises `workspace/diagnostic` (one project-wide pull — the #387 Item 2 fast path). **def**=definition, **tDef**=typeDefinition, **decl**=declaration, **ref**=references, **hov**=hover, **sig**=signatureHelp, **dSym**=documentSymbol, **wSym**=workspaceSymbol, **cAct**=codeAction, **rnm**=rename, **impl**=implementation, **cHir**=callHierarchy; **cmds** = executeCommand allowlist size.
