refactor: remove dead code and consolidate tests (#1335)

Removes dead code and redundant logic and consolidates tests, so there is less to read and maintain. No behavior change.

1. **act/runner**: inline single-use wrappers, compile regexes once instead of per call, embed the trampoline as a string, drop the unused legacy result of `parseActionCommand`
2. **act/container**: `sanitizeConfig` and `mergeContainerConfigs` stop returning the configs they already mutate in place, drop never-set option fields and the unused `user` parameter of `ExecWithCmdLine`
3. **act/common and cache server**: drop the unused `Trace`/`Tracef` loggers and the short SHA of `FindGitRevision`, `RegisterJob` releases through `RevokeJob`
4. **daemon, poller and reporter**: one shutdown wait for both poll modes, drop an unreachable fetch timeout branch, guard the reporter's last report time with its existing lock instead of an atomic
5. **build**: drop unused Makefile and release workflow variables, collapse the goreleaser ignore list to the same build targets
6. **tests**: fold near-duplicate tests into tables with shared setup

Throughout, hand-rolled logic gives way to `cmp.Or`, `strings.Cut`, `slices` and `min`/`max`.
