* perf(producer): extract distributed video frames in each chunk
Plan v2 no longer extracts long constant-frame-rate videos. It ships
each source once and every chunk extracts only the frames it shows, so
Plan time stops growing with video length (#5260).

* test(producer): pin deferred compiled sources to every chunk
Each chunk's page loads every <video> src during session init and a
missing file fails the chunk, so a deferred source under compiled/ must
keep reaching every chunk, as it does on main.

* fix(engine): extract long video ranges in segments and keep plan uploads flowing
A distributed render's plan step extracted a whole video in one ffmpeg process,
so a long clip hit ffmpegProcessTimeout (300 s) however much of Lambda's
15-minute limit was left, and every frame then uploaded in batches of 16 that
each waited for their slowest blob.
Ranges longer than two minutes now extract as two-minute segments that run side
by side, each numbered after the last. They sample the same absolute times as a
single pass, so the frames are byte-identical (checked on a 26-minute, 37,440
frame clip). Plan v2 publishing keeps 32 uploads in flight instead of batching.
On a 10 GB Lambda the 26-minute clip's plan step fell from 395 s to 200 s.
The Lambda docs now state the plan-step length bound.

* fix(engine): split extraction on an integer frame count
The split compared and subtracted float seconds, so 200.3 - 80.3 became
120.00000000000001 s: a second segment got `-t 1.42e-14`, which ffmpeg
rejects, failing an ordinary two-minute range. The frame count now comes from
extractionFrameCountForDuration, the rule a single pass follows, and every
segment takes an exact frame count.

* test(aws-lambda): compare every CDK Lambda payload against the SAM template
#5259 shipped because CDK drops null-valued payload fields when it renders the
state machine, so the construct's source and its deployed definition disagreed
with nothing to notice. This test reads all six Lambda task payloads from the
synthesized definition and requires each to equal the SAM template's, reading
`States.StringToJson('null')` as the null it sends. A field dropped or renamed
on either side now fails CI, not just AssembleV2's audio.

* test(aws-lambda): discover Lambda tasks for the payload parity check
The parity test took its tasks from helpers that name six states, so a seventh
Lambda task on either side would be skipped and the check would stay green.
It now walks both definitions, Map and Parallel processors included, collects
every lambda:invoke task by name, requires the two name sets to match, then
compares each payload.

* test(aws-lambda): key discovered Lambda tasks by their nested state path
Keying tasks by state name let two branches that each hold a RenderChunk
collapse into one entry, so the other's payload went unchecked. Tasks are now
keyed by path (a Map processor as `Map/`, a Parallel branch as `Parallel/<i>/`),
and a regression test keeps two same-named branch tasks apart.

* fix(studio): serve files whose name has a bare percent sign
A browser sends src="100%.png" with the % unescaped, and decoding the whole path threw, so Studio answered 500. Only well-formed escapes are decoded now.
* fix(cli): serve files with a bare percent sign from the check and snapshot server
One shared decode rule for request paths; the image thumbnail route's malformed-escape 400 could no longer fire, so a name that is not a file is a 404.
* fix(cli): name a failed file with a bare percent sign in check
* fix(studio): keep apostrophes and dollar signs in file names when editing attributes
An attribute value is matched by its own quote kind, so src="it's.png" is replaced instead of duplicated, and every insert uses a function replacer, so $1 or $& in a file name is written as is.
* fix(studio): rename references spelled with %20 or & and read quoted media sources
WIP: not yet tested; see the resume note.
* fix(studio): match whole attribute names when editing media sources
* fix(studio): compare decoded names and escape replacement references
* fix(studio): preserve file references across URL and string consumers
* docs: clarify raw file references and URL fields
* fix(studio): keep raw path identity distinct from URL spelling
* fix: share attribute grammar and decode media URLs at their readers
* fix: preserve local filename identity in HTML URL output
* fix: decode entity references before rename candidate matching
* style: format rename entity handling and regressions
* fix: preserve platform file identity when renaming references
* fix(core): decode CSS escapes before rebasing asset URLs
* fix(core): consume CSS continuations before URL encoding
* fix(core): preserve CSS URL identity and escape rebased suffixes
* fix(core): express CSS suffix controls with Unicode categories
* fix(core): preserve URL backslash identity while rebasing
* test(core): respect platform backslash filename semantics
* fix(studio): a dropped file with %, # or ? in its name loads, and an encoded reference renames
* fix(studio): read an authored src as a URL so dropped files with spaces, %, # or ? load
* fix(studio): media routes find files named with ? or #, and the probe reads a src as a URL
* fix(studio-server): one rule for request file paths, so loudness finds files named with %, # or ?
* chore: drop the design note from the change
* fix(core): rename replaced clips whose src is URL-encoded
