Comments and strings: the passes' leftovers, and a region's template matched as one name (#391)

The comment and string passes' last leftovers, and one lookup made to match the reference.

**Comments that stated a wrong reference fact**, now stating the right one:
- A cast failure clears the GCD, and a failed cooldown-on-event spell also drops its parked record (`0x6e73cc`).
- `SetUnit` is `0x505d70`; `0x476cb0` is the component clone it reaches.
- Interior sound follows the character, where the listener sits, not the camera.
- Template inheritance re-runs `LoadXML` on the one object against each template (`0x76985c`), and reads `name` and `id` from the instance alone (`0x769770`).
- On the ghost-to-alive edge the reference clears its corpse cache and sends nothing (`0x5ee990`, `0x491f50`).
- The name cache has no high-bit miss. An empty-name answer evicts the record in the reference (`0x55f6f0`).
- The combat-log deferred queue (`0xc4e208`) waits only on an item name. A unit name never waits.
- A flying spline's segments are paced by curve length (`0x454320`, `0x453760`), not by chord length.
- A stop within 3 yd of its stop point keeps the arrow nocked (`0x6019e4`).
- A missile's sound id is at `CMissile+0x40`.
- A nil or unresolved `AssistUnit` token is a gap against `0xb8` ERR_GENERIC_NO_TARGET, not a deviation.

**Strings:**
- Test, log and tool messages lose leftover history wording and placeholder labels.
- The extractor's scan summaries describe the current tint and sequence-clock paths.
- The smoke script's failure text carries no private numbers.

**Line continuations:** twelve log, panic and assert strings get back the `\` continuations they had lost. Each printed a run of spaces mid-message. Fixes #106.

**One lookup:** a region's `inherits=` is looked up as one verbatim name, matched case-insensitively (`0x6ee6f0`, `_strnicmp` at `0x6ee747`), as `framexml::expand` already did for frames. The gate before it split on commas and matched case-sensitively, so a texture or font string whose `inherits=` spelled its template in another case never received the template. `a_region_takes_a_mis_cased_template` fails before this change and passes after.

**Tests:** the quest tests stop loading three FrameXML files that no quest file uses.

**In game:** nothing changes for the stock UI. Log lines read as one sentence, and an addon texture that names its template in another case now gets it.

Verified with `scripts/check.sh` on the changed crates, plus the loader and quest tests with the install present.
