shoney.arickathil ffd791d05b refactor(porch): name the web framework porch, fix the wo.toml identifier claim
- docs/examples/writeonce-serve -> docs/examples/porch (git mv, history kept);
  `[deps]` key and import are now `porch` / `porch/http` / `porch/router`
- name history preserved on the library README, not rewritten into dated
  records: writeonce-framework -> writeonce-serve (08-25) -> porch (08-26).
  Stories, specs, plans and the audit reports keep the older name by the
  repo's own convention; only live docs and every path link were rewritten
- left alone deliberately: `internal/serve.wo`, `pub fn serve`, `serve_conn`,
  `app.serve(...)` — those are functions, not the module name
- web-app/wo.toml comment corrected: it claimed hyphens are not identifier
  characters and named a key this file never used. lexer.ml's `is_ident_cont`
  DOES accept `-` (an internal dash is part of the identifier, which is why
  binary minus needs spaces), so a hyphenated key would be legal too
- site now teaches the name: package card, the two-deps chapter and the
  handlers-are-classes chapter say `porch`; site-accept asserted the old
  /packages/serve route and caught the rename, as a gate should
- gates: web-app 46/0, site 21/0, deps-accept 8/0, oop-e2e 116/0,
  linkcheck 0 broken / 0 anchors; porch typechecks entry-less as kind=library

-- site — writeonce.de: the language tutorial, served BY the language.
-- Full stack in one binary: porch ([deps]) for HTTP/routing/
-- auth, writeonce-view ([deps]) for server-rendered pages with Tailwind-style
-- utilities, @table + WAL for the chapters themselves. The site is its own
-- final chapter: /ch/serving shows this file's shape.
--
-- SITE_TOKEN=... WO_DATA=./data ./site 8080
-- SITE_HOST=0.0.0.0 ... ./site 8080 (reachable from the network)
-- WO_DIST=/srv/dist ... (where /dl serves tarballs from)
--
-- Behind nginx/caddy for writeonce.de: the proxy terminates TLS and
-- forwards to 127.0.0.1:8080 (the framework speaks HTTP/1.1 keep-alive).
--
-- This file is the BOOTSTRAP and nothing else: seed, routes, serve. The
-- model is types.wo; every feature is a directory holding its view and
-- its controller.
