feat(framework): v1 polish — helpers, 405+Allow, HEAD, Logging, set_header

- App.get/post/put/delete_(pattern, take h: Handler) — the take-interface
  shape probe-proven release + ASan before landing; retires plan-16
  deviation 1; delete_ because delete is the query keyword
- dispatch matches path-first: wrong method on a known path answers 405
  with Allow in registration order; unknown path stays 404
- HEAD routed as GET, body suppressed, Content-Length names the body a
  GET would carry (serialize gains head_only)
- Logging middleware (request line to stderr) ships in router/
- set_header(mut r, name, value) — the builder escape hatch
- web-app registers through the helpers (dogfood); README documents all
- gate grows 14 -> 16: 405+Allow, HEAD-vs-GET content-length equality
- all gates green: web-app 16/0, woc-test 540/0, oop-e2e 89/0,
  deps-accept 8/0, log-watcher 7/0, employee 8/0
- board/story: iteration 17 parked (spec+plan ready on library-internal),
  16 carries the v1-polish landing, order list updated

 ## ▶ NEXT PLAN
 
-**The web framework becomes a first-class library — iteration 17.** The goal
-shifted 2026-08-20: the previous NEXT PLAN ("make log-watcher executable —
-nothing else") was met in full 2026-08-15 (milestone record below), and the
-driving workload is now `docs/examples/writeonce-framework` consumed by
-`docs/examples/web-app` through `[deps]`. Iteration 17's forks are settled
-(decisions + framework/compiler/VM/GC impact in
-[the iteration](stories/language-runtime-database/17-library-projects-internal.md));
-what remains, in order:
+**Framework v1 — a polished micro-framework (routing, middleware,
+`Req`/`Resp`), nothing MVC-scale.** Directive 2026-08-20: iteration 17
+(library kind + `internal/`) is **parked** — spec + plan approved and ready
+on branch `library-internal` — and the framework itself is the work. The
+v1-polish slice landed the same day (branch `framework-v1`): registration
+helpers `get/post/put/delete_` (the take-Handler shape, probe-proven),
+405 + `Allow` on wrong-method hits, HEAD served as GET with the body
+suppressed, a `Logging` middleware, `set_header`; `just web-app` grew to
+16/0. En route it exposed and fixed a real emitter bug: a Text-typed
+single-segment interpolation of a place (`"${r.method}"`, `r` a loop
+borrow) crossed `let`/assignment boundaries uncopied — aliased the field,
+crashed the release build; `copy_place_text` now sees through `Interp`
+exactly as `drop_fresh_text` does, pinned by
+`tests/corpus/run/interp-borrowed-field`.
 
-1. Merge the `web-framework` branch to master (iterations 15–17 docs + code,
-   local only). Why first: everything iteration 17 edits exists ONLY on that
-   branch — the framework and web-app sources, the `[deps]` resolution code
-   in `compiler/bin/main.ml` (17's `internal/` rule lands in that exact
-   code), and the `just web-app` regression gate. Starting 17 unmerged means
-   stacking a branch on an unreviewed branch; merged, 17 is a small clean
-   diff off master.
-2. Spec + plan from the settled decisions (prose only, per convention).
-3. `kind = "library"` in `wo.toml` (default `"program"`): `woc <dir>` on a
-   library runs the FULL pipeline as a check — parse, typecheck, borrow
-   check, GC inference — with no entry required; an explicit build still
-   works when a `main` exists (dual lib+bin).
-4. The `internal/` rule at the `[deps]` boundary: a consumer `use` of a dep
-   path containing the segment `internal` is a new WO-E1xx at the `use`,
-   naming the dependency; inside the dep it stays legal.
-5. Framework reorg: request-parser and serve-loop plumbing move under
-   `internal/`; the public surface (`Handler`, `Middleware`, `App`,
-   `Req`/`Resp`, builders) does not move.
-6. Gate: `just web-app` stays 14/0, plus new checks — library check without
-   an entry succeeds, a consumer `internal` import is refused, and the
-   iteration-16 `--emit` verification workaround is deleted.
-
-The VM and GC are untouched by design — visibility is compile-time name
-resolution, libraries compile whole-program into the consumer's image, and
-GC inference stays whole-program (app usage may promote dep classes; that is
-intended).
+Next per the implementation order (17 parked): finish the half-done
+database branches — 9c (ipc-attach: manifest + binding) and 9d
+(keypair-auth: manifest) — both need their forks brainstormed before
+planning.
