9ac8ff28ec Correct release-blocking README and startup-warning inaccuracies (closes #151)
All checks were successful
check / check (push) Successful in 3m10s
The empty-TRUSTED_PROXIES warning was gated on IsProd(), but
WEBHOOKER_ENVIRONMENT defaults to dev, so an internet-exposed
deployment whose operator never set it got no warning at all — the
exact operator error the warning exists to catch. It now fires whenever
the list is empty, in any environment, and its text is accurate both
behind a reverse proxy (shared buckets, remotely deniable admin login)
and with nothing in front of the process (harmless). The startup
configuration summary also now logs sessionIdleTimeout, the one value
where a valid setting silently disables a security control.

The README documented a two-stage Docker build on golang:1.24 running
"make check" (the tree has three stages: a golangci-lint lint stage
running fmt-check and lint, a golang:1.26.1-bookworm builder running
test and build, then the Alpine runtime), advertised the public
receiver as accepting all methods (it answers 405 to everything but
POST), claimed unqualified per-IP login rate limiting, and left the
session-expiry prose orphaned inside the trusted-proxy subsection.

The rest of the README was swept against the code rather than only the
reported lines: every documented route checked method-by-method against
internal/server/routes.go (adding the password-change, entrypoint and
target routes that were missing), every environment variable checked
against internal/config/config.go (MAINTENANCE_MODE serves no
maintenance page — it only sets a healthcheck field), the fx wiring,
package tree, prerequisites and dev commands brought back in line with
the tree, and two statements known false from other reviews corrected:
the body-size limit does not reject before "any other middleware" (the
eight global ones run first), and a retention value at or above the
retain-forever sentinel is accepted rather than 400ed.

TODO.md drops the unsupported half of its CI claim, keeping the
cache-defeated container runs, and splits the landed password change
away from the unimplemented reset flow.

## Third-party browser assets
The web UI serves one third-party script, Alpine.js. It is **not** committed:
a minified bundle in the tree is unreviewable, and `REPO_POLICIES.md` bars
both committed build artifacts and unpinned external references.
Instead `script/fetch-assets` downloads it from a pinned URL, checks the
download against a hardcoded sha256, and installs it under `static/`. The
sha256 of every installed asset is recorded in `static/vendor.sha256`, and
`static/vendor_test.go` re-hashes the bytes `go:embed` put in the binary
against that manifest — so the pin is enforced on what actually ships, not
merely written down. Any mismatch fails the build.
`make bootstrap` runs the fetch for local development, and the Dockerfile
runs it in the build stage; `.gitignore` and `.dockerignore` keep the
artifact out of both the repo and the build context.
To move to a new version: update the version, URL, and tarball sha256 in
`script/fetch-assets` and the asset sha256 in `static/vendor.sha256`, then
run `make assets && make check`.
