feat(input): action maps + deterministic record/replay (#7)
The two ideas the input revamp leads with, built in Ludic over the
single-key poll every target already provides:

- Action maps: gameplay reads named actions, not physical keys, so keys
  are rebindable and a scheme is data. Input.bind(action, key),
  Input.down/pressed(action), Input.rebind(action, from, to).
- Deterministic record/replay: Input.poll() is the one per-frame input
  read; Input.record() captures the key each frame and Input.replay()
  feeds the tape back, so a run reproduces exactly — the seed of lockstep
  netcode. "Read input" and "read a recorded snapshot" are the same call.

runtime/native/input.ludic (spliced when the new Input.* methods are used;
pulls in core.ludic for rt_poll). emit_ns_call routes the methods to the
@fn_input_* runtime; parse.ludic gates the splice. Seven docs/language
pages; worked example + regression examples/library/input_actions.ludic
(1 0 1 1 0 1 0). Full suite 75 passed, self-host fixpoint intact, no golden
drift. The device layer (multi-key held, gamepads, touch, analog) needs a
platform key-state backend and is tracked separately.

Changesets

A changeset is one small Markdown file describing a single user-facing change, dropped in this directory. x release consumes every changeset here into a new CHANGELOG.md section, bumps VERSION, and deletes the consumed files.

Format

bump: minor
type: feat
One or more lines describing the change, in the past-agnostic imperative used in
the changelog. Markdown is fine.
  • bump: — major, minor, or patch (SemVer). The release version is bumped by the highest level among the pending changesets (unless x release <level> overrides it).
  • type: — the Conventional Commit type (feat, fix, perf, docs, …); it becomes the bold prefix of the changelog bullet.

Adding one

Create a file with a short, unique name, e.g. changes/regex-namespace.md. Any filename works except this README.md, which the release step always skips.
