docs: consolidate runner-aware changelog entries (#463)

## Motivation

The runner-aware tooling work has landed as a stack of focused PRs, but the changelog had accumulated one release-note item per implementation slice. This PR keeps the stack reviewable while presenting the feature as one coherent runner-aware caching update in release notes.

 # Changelog
 
-- **Added** Runner-aware tools can now call `ignoreInput(path)` to exclude non-semantic reads from auto-inferred task cache inputs.
-- **Added** Runner-aware tools can now call `ignoreOutput(path)` to exclude non-semantic writes from read/write overlap checks.
-- **Added** Cached tasks can opt into automatic output restoration with `output: [{ auto: true }]`.
-- **Changed** Cached tasks now automatically restore written output files when `output` is omitted; use `output: []` to disable output restoration.
-- **Changed** Tracked environment values in task cache fingerprints are now stored only as SHA-256 digests, and env-related cache miss details report names without values.
-- **Added** Runner-aware `getEnvs` match sets can now participate in task cache fingerprints, so changing, adding, or removing a matching env var invalidates the cache ([#450](https://github.com/voidzero-dev/vite-task/pull/450)).
-- **Added** Runner-aware `getEnvs` calls now return env values served by the runner for matching env glob patterns ([#449](https://github.com/voidzero-dev/vite-task/pull/449)).
-- **Fixed** Runner-aware `getEnv` reads now affect task cache fingerprints, so changing a tool-served env value invalidates cached output and names the env var in the miss message ([#454](https://github.com/voidzero-dev/vite-task/pull/454)).
-- **Added** Runner-aware tools can now opt the current task run out of caching through the new IPC channel; Vite dev server integration uses this automatically ([#441](https://github.com/voidzero-dev/vite-task/pull/441))
+- **Added** First-party support for caching `vite build` with zero cache config, giving Vite projects correct cache hits out of the box ([vitejs/vite#22453](https://github.com/vitejs/vite/pull/22453)).
+- **Added** [`@voidzero-dev/vite-task-client`](https://npmx.dev/package/@voidzero-dev/vite-task-client), allowing tools to report cache information to Vite Task at runtime so users do not need to configure it manually ([#441](https://github.com/voidzero-dev/vite-task/pull/441), [#454](https://github.com/voidzero-dev/vite-task/pull/454), [#449](https://github.com/voidzero-dev/vite-task/pull/449), [#450](https://github.com/voidzero-dev/vite-task/pull/450), [#458](https://github.com/voidzero-dev/vite-task/pull/458), [#431](https://github.com/voidzero-dev/vite-task/pull/431), [#459](https://github.com/voidzero-dev/vite-task/pull/459)).
+- **Changed** Cached tasks now restore automatically tracked output files by default; use `output: []` to disable restoration ([#460](https://github.com/voidzero-dev/vite-task/pull/460), [#461](https://github.com/voidzero-dev/vite-task/pull/461)).
+- **Changed** Environment values in task cache fingerprints are now stored only as SHA-256 digests, and env-related cache miss details report names without values ([#455](https://github.com/voidzero-dev/vite-task/pull/455)).
 - **Fixed** Prefix environment assignments like `PATH=... command` now affect executable lookup during task planning, so tools provided only by the prefixed `PATH` can be resolved correctly ([#440](https://github.com/voidzero-dev/vite-task/pull/440))
 - **Changed** Cache misses caused by a tracked env var now name the env var inline, for example `cache miss: env 'NODE_ENV' changed`, instead of the generic `envs changed` message ([#438](https://github.com/voidzero-dev/vite-task/pull/438))
 - **Fixed** The task cache is now stored in a per-schema-version subdirectory (e.g. `node_modules/.vite/task-cache/v13/`), so switching between branches that pin different Vite+ versions no longer fails with `Unrecognized database version`. Each version keeps its own cache directory; a cache from a different version is ignored rather than aborting the run ([#433](https://github.com/voidzero-dev/vite-task/pull/433))
