chore: add Renovate, refresh deps and test the Gleam floor and latest

[nao1215]

Summary

Nothing updated this repository's dependencies automatically, so manifest.toml fell behind and CI stayed on Gleam 1.15.2. This adds the shared Renovate preset, refreshes the manifest, lowers the declared compiler floor to what the package needs, and runs CI on that floor and the latest Gleam 1.x.

Changes

• renovate.json: extends github>nao1215/renovate-config (rangeStrategy: widen, weekly lock file maintenance). Renovate updates gleam.toml ranges, manifest.toml, .mise.toml and GitHub Actions.
• manifest.toml: gleam update within the existing ranges (gleam_stdlib 1.0.5, gleeunit 1.11.0, glinter 2.19.2 and transitive packages). No range needed widening.
• gleam.toml: the floor goes from >= 1.15.0 to >= 1.14.0. 1.14.0 builds and tests the package unchanged on both targets, and gleam_stdlib 1.0 already requires 1.14.
• src/: reformatted with Gleam 1.18 (line wrapping only).
• .github/workflows/ci.yml: new floor job (Gleam 1.14.0, OTP 27, Node 22, Erlang and JavaScript tests). check and build-and-test move to Gleam 1.x and OTP 29; Node uses lts/*. actions/checkout and actions/setup-node go to v7.
• .github/workflows/release.yml: uses the latest lane, since the build job runs just format-check.
• .mise.toml: Gleam 1.18.1 and Erlang 29.0 so local formatting matches CI.
• CONTRIBUTING.md, CHANGELOG.md: Gleam 1.14 requirement, changelog entry.

Design Decisions

The latest lane floats on 1.x because Renovate does not update gleam-version, and the floor lane is pinned to the patch so it proves the declared >= 1.14.0 itself.

Verified locally: Gleam 1.18.1 / OTP 29 passes format, glinter, build with warnings as errors on both targets and 101 tests on each target; Gleam 1.14.0 passes the same tests on both targets.

Summary by CodeRabbit
