fix(qwik-vite): readable names for split segment chunks - #9386
Since #9263 and #9309, debug builds name each split segment chunk segment_<hash>.js. They now use the segment's canonical filename again, e.g. counter98.tsx_counter98_component_Fragment_button_q_e_click_ppvuTaDoEGk.js. An entry chunk whose code lives in another chunk ends in -entry, and debug file names stay under 200 bytes.
Summary by CodeRabbit
New Features
Debug builds now use readable names for event-handler and visible-task chunks, making generated files easier to identify.
Bug Fixes
Event-only chunks now use their canonical filenames instead of generated hash-based names, while manually configured names retain precedence.
Long debug chunk filenames are shortened to avoid exceeding filesystem limits, while preserving distinguishing information. Additional entry chunks receive an -entry suffix where needed.
Debug builds named these chunks `segment_<hash>.js`. The `segment_` prefix
stays: Rolldown renames a group that takes the segment module's own name
(`app2.tsx_...`).
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Event-only segment entries and smart client-only chunk names now use canonical filenames instead of hashes. Long chunk names are shortened to a 200-byte limit. Tests cover the naming behavior and filename limits.
QwikDev/qwik#9309: Assigns hash-based entries to event-only QRLs in smart mode; this PR changes those entries to use canonical filenames.
QwikDev/qwik#9263: Groups smart client-only segments under hash-based names; this PR changes those names to use canonical filenames.

Assert the parent entry for render-used callbacks.
When render uses alias, the test only checks that the callback is not named with the canonical filename. A stale segment_${hash} entry can also pass this assertion. Assert test.tsx_entry_App for the false cases.

Strengthen the callback entry assertion in the event-QRL test so render-used
callbacks in the false cases must have the parent entry test.tsx_entry_App,
rather than merely not matching the canonical-filename segment. Preserve the
canonical-filename segment expectation for separated callbacks.

limit the readable portion so generated filenames stay within filesystem limits,
while retaining a unique suffix. Apply the same naming behavior in both
optimizers and the smart client-only path.

A long segment or entry name could pass the 255-byte file name limit and
fail the build. Long names keep their start and end around a hash of the
full name.

A segment's emitted entry chunk takes the segment's name too, so Rolldown
renamed the split chunk (`app2.tsx_...`). Debug builds now add `-entry` to
an entry chunk whose module lives in another chunk.
